I also feel like I should re-read it, haha. 

Yeah, that makes total sense. I feel like we could alter the ending to our advantage depending on what we want to do. Wasn't Snow sick? I wouldn't mind us keeping him around because he was, weirdly enough, one of my favorite characters, and he never did lie to Katniss. Maybe he wouldn't lie to Prim and Gale as well if she's missing, or incapacitated to a point? Coin, we could keep alive. Maybe she fled back to 13 where she's got some kind of plan to take control of Panem? These are just ideas off the top of my head, we don't have to use them.
