One day, during school, Carl took Molly's computer while they were doing work. He then used the computer to message her boyfriend, Callum, that she wanted to break up with him.This left both, Molly and Callum, a total wreck the next day because she was unable to contact him afterwards to clear the situation.

Molly can be a bit of a push-over, allowing people to take advantage of her and her kindness. But, the moment you hurt someone she cares about, she is not afraid to drop you.
