See, I adored him right off. xD Just the way he was constantly screwing with Katniss's head, offering sugar cubes, and then helping her with that knot in the training area (from behind, all sexy-like ;D ).
Then, there was that phase where we were all "Oh s**t, is he working for Haymitch or is he just another tribute looking for a kill?"
And then as the story progressed, and we found out about Annie, he just grew on me even more. The guy just had so much character depth.
And then, when he died, it crushed me.
Everyone's favorite character, and he dies in such a stupid way. I was so angry. And they mentioned the mini-Finnick that Annie had given birth to, and I was all..."Just this one time, you get a get out of jail free pass, Ms. Collins."
His death was so quick that I had to go back a whole chapter because I misread it (I think it was 3 o'clock in the morning too) but I was all "Wait, where the hell is Finnick?! Katniss hasn't mentioned him in a while."
