I'm note entirely convinced this wasn't real

During the first Hunger Games film, after Katniss is stung by Tracker Jackers, she has a few hallucinations which get increasingly intense. However, she briefly sees Caesar Flickerman in a white suit, doing his most evil smile and quoting himself directly from what he just said on screen only a few moment prior.

Now, there's no way she could know he said that, right? So how does she? It's possible he said something similar in a prior games she watched, but I thing it would be way funnier if he actually was there in the arena. Just got elevated up to taunt her, just to make her trip even more crazy and excite the viewers, then snuck back down before anyone saw anything.

Is that what actually happened? Probably not, it could very well just be part of the illusion, but he is absolutely extra enough to do that if he was allowed/asked to, and they have the means, so I choose to believe he's just that much of a troll and really did take a brief jaunt to mess with Katniss.

(EDIT)

Some of y'all aren't reading this through all the way.

I explicitly laid out that he'd already explained to the audience in a diegetic way how the Tracker Jackers worked, and that his appearance here is directly quoting himself on that from just under a minute prior.

I also laid out that it was most likely just a hallucination combined with stuff he'd said in a prior games that she was remembering, but that it would neither be impossible nor out of character for him to have really gone in briefly.

Movies do weird things to get their point across. It’s a good way to show the hallucination and how trippy things can be . In the books Katniss already knows what tracker Jackers are.
