Cilla is extremely desperate for companionship. She hates the feeling of loneliness and is constantly looking for others to reassure her and help her. Being all alone is her absolute worst fear. That's why Cilla tries to be as nice and sweet as possible to everyone she meets -- she won't risk them not liking her. She develops attachments very quickly, and the people she cares about are a driving force in her life. She has no idea what she would do without her family and friends.
While Priscilla is fairly clever, and does well in school, in real life situations she tends to think with her heart -- not her head. She will make silly, reckless mistakes that could have been avoided if she'd thought about it a little more. That is, if she makes any decisions at all. Cilla is extremely indecisive and likes to leave the control to other people. No thank you, leadership roles are not for her. She's fine with just going with the flow -- being in power is too much for her.
At her core, Priscilla Graham is a very sensitive, caring individual who gets emotional easily and would do anything for her family and friends. She will always be there to listen to your problems (even if she will probably be in tears by the end of it).
Priscilla's father left when she was very young, and her mother worked multiple jobs, leaving her craving love. So, she made as many friends as possible, people being naturally drawn to her awkward self. Cilla was very well loved in her little town.
So of course, everyone mourned for her when she got into a tragic accident at the age of 19. She had moved to Toronto to go to the University of Toronto, and one of her fellow psychology students had pushed her into a lake as a joke. It didn't end well -- she had been weighed down by her heavy backpack which was strapped to her body. Priscilla drowned to death.
