I loved Evie and Nick's relationship to death, however borderline-incestuous it may have seemed at times. Nicky is the sweetest, purest kid and he's such a good person that it breaks my heart. He brought out the best in Evie and she would do anything to protect him or make him happy. Even give him up to Tegan. And that's not even going into the awesomeness that was Peter Pan.
Illy, I never got to play with as much as I would have liked, but she is so sassy and awesome and I always stalk her and Cole because they are just that good together. Her and Stefan had such a fun dynamic as well, and I'm sorry that Rosalie never got to meet her outside of the full moon.
