Liam is her twin brother
She doesn't reveal herself very much. When you first meet her she will be shy or aggressive. Both are covering up a past she wont talk about and the fact that she is yearning for companionship. If you stick at her and become her friend (witch can be hard or easy) you will be rewarded.
She always has a hidden knife in her boots.
She has a hard history that is really hard for her to talk about. If you get close to her she might spill if you see the knife. She gets started and cant stop.
