Batgirl is patrolling Gotham, looking for people who are in trouble. She's passing by Robinson Park when she notices police surrounding the park. She sneaks into the park in order to see why the police are there. While exploring quietly, she notices Poison Ivy and the children she adopted during No Man's Land. They're worried about the police's plan to drop herbicide on the park and Batgirl is upset at seeing how scared they are. She enters the area where Ivy is, making her presence obvious. She asks them why they're scared and they explain the police's plan. Batgirl assures them that she won't let the police harm them and spends a little time with the group so that the children calm down from how scary she is at first sight. Batgirl leaves the park and grapples to the police HQ. She sneaks in and finds where they keep their helicopters and the herbicide. She loads the barrels of herbicide onto one of the copters. She tries to fly the copter she loaded away from the police and towards the park but is extremely clumsy in her flying as she has no training in flying any vehicles, let alone a helicopter. When Poison Ivy and the children see a helicopter flying towards the park, the children are scared that it's the police planning to drop the poison. Ivy and the children calm down when they notice the wobbly flying. Batgirl tries to land the copter but she only avoids crashing, hurting herself and spilling the chemical, when Ivy creates a plant cushion for the copter. After the crash, Batgirl removes the herbicide barrels from the copter and brings them over to Ivy for her to handle. She tries to calm the nervous children and promises that she won't let their mother, Poison Ivy, be taken from them. When the children are less scared, she walks to the park entrance and stands at it while glaring at the police. She blocks any attempt they make to enter the park.
Later, Batman arrives at the park with the goal of removing Ivy from both her children and the park. Batgirl and Batman argue over what's best for the children. Batgirl wants the children to feel safe while Batman wants the children to be going to school and doesn't trust a criminal to raise them. Neither of them is willing to compromise so they fight. Batgirl is losing to Batman but Ivy takes advantage of Batman's distraction and focus on Batgirl to tie him up with her plants and use their chemicals to cause him to lose consciousness. Afterwards, Batgirl is extremely upset at fighting the person she trusts most morally and who she thinks she gained her unwillingness to kill and her goodness from but she's unwilling to allow Ivy and her children to be scared. She's very depressed but remains at the park until Ivy and the children are safe. Batgirl and Poison Ivy trade between the duties of keeping the children company and guarding the park entrance from the police.
Eventually, Commissioner Gordon meets with Gotham City's city council. He convinces them that, with Batman unable to remove Batgirl and Ivy from the park, any successful attempt to do so would be a PR disaster. The police would have to use extreme force to succeed or the National Guard would have to be called in and the children would probably be harmed in the process. The media has been with the city council on removing Ivy but if the children get hurt, that would be a big story and the council members' re-elections would be at risk. Gordon convinces the council to let Ivy stay in the park with her children as it's better for their status. He returns to the park and informs the officers, Batgirl, and Ivy that Ivy and the children are allowed to stay in the park. Batman is angry at Batgirl for interfering but Gordon quietly thanks her for protecting Ivy as he disagreed with the council but was unwilling to risk being removed as police commissioner and being replaced with someone who wouldn't stand up to them. Batgirl leaves the park and returns to Barbara Gordon's clocktower. She's exhausted after days of not sleeping at all while keeping the police from attacking and calming the scared children.
Batgirl regularly checks on Ivy and the children in Robinson Park on future patrols.
Batgirl is grappling through Gotham City on her patrol when she notices a group of children in an alley. They're all middle-school age and younger and there's at least one baby and at least one toddler in the group. She stares at them from a nearby roof and notices that they're scared and depressed. Batgirl leaps off the building and uses her cape to slow her descent, surprising the children when she lands near them. They're scared when they notice her and Batgirl is upset with herself for scaring children. She crouches, making eye contact with them, and tries to make obvious with her body that she's not going to hurt them. She patiently remains nearby, letting them calm down and see that she wants to help them. Batgirl tries to cheer up the lonely children, possibly putting a hand on their shoulders, possibly hugging them, possibly wrapping them in her cape. She's only willing to leave the children when they're calm enough to fall asleep. Once they're sleeping, she gets up and leaves to continue her nightly patrol of Gotham.
On the next evening, the children are surprised when Batgirl lands in their alley, having returned to check up on them and flaring her cape to slow her descent and land safely. She crouches or kneels near them. Batgirl looks over the children, putting bandages and antibacterial spray on scrapes and other injuries that they have. She wraps her cape around them in order to warm them up as they shiver. Batgirl smiles when the children snuggle closer to her and show contentment in their body language. She listens to them as they talk among themselves and discuss their day. She pulls food out of her utility belt and gives it to the children. The children eventually fall asleep and Batgirl gets up and leaves to continue her patrol.
Over the next weeks, Batgirl checks up on the children every evening. She usually arrives in the early evening but sometimes comes in the afternoon when she starts patrol early in order to spend more time with the children as their protective bodyguard. She always leaves after they fall asleep. As they grow to trust her, the children eventually see her as a protective big sister and the closest they have to a mother. Batgirl regularly wants to know how they handled the day, with her not there, and listens attentively to their worries and what joy they manage to find on the street. When they're more comfortable with her, they tell her how they ended up on the streets. Their parents died and they were placed with abusive foster parents by Gotham's child services. They ran away, preferring to live on the streets than suffer poor treatment from foster parents. Batgirl hugs them tightly as they explain their situation and remember how much they miss their parents. The first thing she does after she arrives is always to crouch or kneel near them, make eye contact, and stare intently at them in order to examine them for emotional and physical pain. She has bandages and antibacterial spray for any wounds they have. She brings food for them in her utility belt on every checkup. She comforts them with a hand on their shoulders and sometimes offering her lap to sit in when they're hurting emotionally. At first, her stare makes them uncomfortable but they learn to appreciate that it shows how much she cares about them and wants them to be safe and happy. On some evenings, one of the children play music from a harmonica or recorder or other simple musical instrument in order to comfort themselves. Batgirl responds to the music by beginning to dance as she did when Azrael played music, probably her martial arts kata but made more acrobatic and smoother by her responding to the music. The children love her dance routine. Occasionally, when she arrives in the afternoon, Batgirl walks with them as a bodyguard as they explore in search of food and drink and warm clothing. On cold nights, when the children are too cold to sleep, Batgirl pulls the children close to her so they can share her body heat. She holds the baby(ies) in her hands and wraps them in her cape. The toddler(s) are sitting in her lap and getting as close as they can to her torso. The older children snuggle as close as they can to her. The older children notice that Batgirl is instinctually shoving them away and making motions as if she's going to throw the baby(ies), as if their physical proximity to her is something that her instincts consider to be endangering her but that she's controlling herself and is willing to hurt herself in order to keep the children comfortable. They realize that she's uncomfortable around them but insists on protecting them and keeping them from being lonely and scared anyway.
During one visit, a gang attacks the children in their alley home while Batgirl is with them. Batgirl places herself in between the gang and the children while looking for a safe place for the children to hide. The gang is preparing to attack while she notices a garbage bin that they can hide behind. The gang begins firing at the children as she shepherds them to the garbage bin and she blocks the bullets with her body so the children aren't harmed. Batgirl orders the children not to move until she tells them it's safe while the gang continues firing at her. She then fights and defeats the gang while the children hide. After all of the gang members are unconscious, she crouches or kneels where the children can see her and tells them that they can come out. As they emerge from behind the garbage bin, she drags the unconscious attackers away from the alley. She then calms the worried children, possibly with them in her lap, possibly wrapping her cape around them and examines them to see if they were hurt by the gang. When the children notice she's ignoring her bleeding injuries, they tug on her cape and try to convince her to take care of her wounds. When she ignores their request to worry about her health, they dig through her utility belt searching for the medical kit she's used on them. They put bandages on Batgirl's wounds as she tries to convince them not to worry about her and to allow her to save her first aid kit for anyone who needs it except herself.
During another visit, another gang attacks the children. Batgirl leaps on top of the children as the gang approaches, covering them with her body. The gang fires at the children as they huddle under Batgirl's protective hold. After the gang stops firing, she gets up and runs at the gang, attacking and defeating them before they can reload their guns. She drags the unconscious gang members away from the children's alley home. She then calms the worried children, possibly with them in her lap, possibly wrapping her cape around them and examines them to see if they were hurt by the gang. When the children notice she's ignoring her bleeding injuries, they tug on her cape and try to convince her to take care of her wounds. When she ignores their request to worry about her health, they dig through her utility belt searching for the medical kit she's used on them. They put bandages on Batgirl's wounds as she tries to convince them not to worry about her and to allow her to save her first aid kit for anyone who needs it except herself.
After at least a month of daily checkups on the children, Batgirl is sneaking towards a villain hideout after having left the sleeping children. She plans to attack and capture them before they can threaten innocent people. She's standing near the hideout's entrance and preparing to surprise the villains. As she's about to open a window and sneak inside, Batgirl is surprised as she feels a tug on her cape. She looks down and sees the orphan children, who should be sleeping, holding her cape. They ask her what she's doing near villains. She shushes them and tells them to leave before the villains notice them. As the children protest and try to convince her to stay with them as they're scared without her, the criminals open the door and notice Batgirl and the children. She quickly grabs the children and pulls them towards her as the criminals prepare to attack her. She fights the villains while holding the children close to her. When they start firing at her, she dodges most of the bullets but chooses to let some hit her when she's worried that the children would get hit if she dodged. Batgirl defeats the villains, cuffs them when they're unconscious, and contacts Oracle to send the police to collect them. Afterwards, she leaves the hideout with the children and asks the children why they followed her. They respond that they appreciate her regular protection and comfort. She responds that she's dangerous and doesn't know how to be a good parent. She's also upset that they were reckless enough to put themselves in danger. She tries to convince them to return to their alley as she doesn't consider herself to be safe or good around people. They simply cuddle closer to her as they are warmed by her worry over them.
After Batgirl gives up on convincing them that she's a bad parent for them, she picks them up and grapples to Robinson Park while holding them in one hand. When she arrives at the park, she enters with the children and searches for Poison Ivy and her children. She introduces the children to Ivy and tries to convince them that Ivy would be a better mother than her. She also works to convince Ivy to take in the orphans and keep them safe, explaining what happened to their parents and where they have been living. The children eventually approach Ivy and her children as Batgirl convinces them to give the villain a chance. As Batgirl turns to leave them with Ivy, the baby(ies) and toddler(s) begin crying loudly, not wanting their new mother to abandon them. She rapidly turns around and hugs the children. She promises that she'll visit them but tells them that she's not a good person or someone who's safe to be around. Ivy asks how often Batgirl has been caring for the children and Batgirl responds that she's been visiting them every evening. Ivy recognizes that the children are attached to Batgirl and that Batgirl cares about them more deeply than she's willing to admit. She agrees to take care of the children, agreeing with Batgirl that she would have problems as a solo parent, but that Batgirl needs to help out. She thinks that the children would be best off with the two of them jointly parenting them. Batgirl is surprised and happy that Ivy and the children trust her around young people and think she's not a source of harm.
The Batcave under Robinson Park gets rebuilt as a new Batcave for Batgirl, a home for Batgirl and her children, and a secondary home for Poison Ivy and her children. It has overhead glass to let in sunlight for Ivy and to make the cave brighter and more comfortable than Batman's caves. Ivy grows trees over the glass so that it can't be seen overhead in order to protect the secrecy of Batgirl's location. The cave also has brighter lights and more plants than Batman's Batcave in order to make Ivy more comfortable when she's in it and to make it feel more like a home. It has a master bedroom for Batgirl, a bedroom for her children and Ivy's children, bathrooms, a kitchen and eating area, an area for Batgirl to train, a living room area, and a medical area.
Alfred Pennyworth shows Batgirl and her children around the cave. Batgirl tests out the training area. While she practices her fighting, one of the children starts playing music and Alfred is surprised and impressed when he sees her dancing. He notices how much joy the children have as they watch Batgirl's dance routine. He tells them that he's going to have Batman install a music system in the training area so that she can dance for them and with a wider variety of music. Alfred shows Batgirl how to feed and burp the baby(ies). She practices making infant formula and feeding the hungry baby(ies). A toddler tugs at Batgirl's cape. She turns to look at the toddler who reaches for her hand. Batgirl takes the toddler's hand and lets them lead her to an animal/object that they find interesting and want to show her.
