I loved that Scott killed Xavier. Xavier's first student and almost his son is the one that killed him. Great moment for Scott and Xavier. Scott will still be my favorite character in all of comics even though he killed his mentor. Also why is it that when Jean was taken over by Dark Phoenix all her friends stuck by her and yet before Scott does they all turn on him? I read the issues and all but that kind of upsets me that everyone would turn on him and not on Jean.
Probably because when Jean was the Dark Phoenix they didn't fully understand the power. Now that they do and they see what happens to the host they won't trust it.
