That's a good idea. I think 11 would have sent their rebels, or 13 to see if anyone survived. I have this image in my head of Gale and Prim kind of raising Posy together and it's sweet and sad and ugh, everyone is going to be so traumatized from this. They deserve all of the good things happening now because they don't even know the pain they're about to experience. 

Also, posted! Katniss doesn't have to leave, btw. Haymitch would prefer that she stay, but do with it what you will~
