Even though he wasn't technically a character until the fifth book Tomas Tod was one of my favorite characters and then he went and turned evil! I am still soooooo mad at Heather Brewer. I bawled so hard when I found out he was evil. I literally felt betrayed. I refuse to acknowledge the existence of the fifth book most of the time.
I was pissed the Nell died!!!! I didn't like Tomas when he first came into the book, so I didn't care that he was bad. It actually made sense in my head for him to be bad
See, before he was a character besides in Vlad's memories, I had pictured him in my head, so he was a character to me and then in the fifth book he was all...ick. And he killed Nelll, and it sucked.
