When Evan first woke up after dying he was terrified. He was surrounded by nothing but darkness and everything hurt. Then Charlie came and he wasn't alone. And he finally had a friend, Charlie would spend all of her time playing with him and telling him stories.
Then when the MCI happened he got even more friends. He hated how sad they were at first but after a bit of talking most of them understood that instead of focusing on killing William they should just have fun. But every time he tried to have fun Charlie would always get to talking about how they needed to "kill William". Evan didn't get that since his dad was wonderful he had given Evan brand new friends after Michael had been so mean to kill him and leave him alone.
So he started to dislike Charlie
