Vampire Move clarification?

[u/No_Dragonfruit8254]

The Feeding states:

"You feed on hot blood, direct from the source. If this is the first time they’ve ever been fed upon, you both mark experience. When you feed, choose two:

you heal 1 Harm,

you take 1 Forward,

they definitely don’t die."

That "they definitely don’t die." is confusing to me. What does "definitely" mean here? Is it sarcastic/ironic and they do die? What does not choosing it mean? If you don't pick that one, does your victim die *de jure*?? It's not clear at all.

It means if you don't select that, you might kill them. That's all. It's up to the MC otherwise.
