So...is that dude with the pointy eye the betrayer? GAHHHHH, I only read the novel in passing, but if I'm not mistaken, isn't that dude the one that cause the lack of security for the rebel act and what caused dorarea(?) to die? AHHHHHH, I FUCKING HATE HIMMM. I remember reading the novel and after the rebel part and how that fire son of a bitch died, I stopped reading because it got too intense for me. But anyway, my point is, HE NEEDS TO DIE, UGLY SON OF A BITCH
