That's why they recast >__> someone ate Buttercup 1.

Fine! I won't! I can play this game too!

I could see her doing that. It might be fun to have something good happen before the games, at least try to perk up everyone's spirits. Those ages sound about right to me. And yeah, I imagine Prim vs everyone will happen right before they escape the arena, so tensions will be higher when they realize Peeta isn't coming and their plan is pretty fucked. Then she'll have to make up with Katniss and she'll feel really awful for saying whatever because Katniss has done so much for her, and she still thinks she's personally responsible for Katniss being in the Games. Let's face is, Katniss and Haymitch are forever going to be butting heads, haha.
