She also is friends with most of the Lost Boys in the team.

Defecting from the Dark Side to the Light
"The only reason I was still here was because of your demands to read your friends stories every now and then, look after them, treat their wounds! We only made a deal: that I be your stupid mother figure, while not any more. I'm finding a way out of this island, and there is nothing you will do to stop me!"
