I do sorta see why you like him (though I personally don't). He is somewhat the instigator, because if it weren't for him, we wouldn't really have Catching Fire, or Mockingjay.
I like Haymitch and Effie. I think they're both really cool, even tho Haymitch is a drunk and Effie is just annoying. Without them though, Katniss and Peeta wouldn't have been able to survive.
Gale because he really hold the most specialest (that is probably not a real word) place in my coração XD
and Cato. I used to totally be in amor with Cato mainly because there was just something so ..evil..and yet the ending was just horrible. Now I don't really think about him much (because I found Gale!!) but I have to admit the actor playing him is hot xD
