Motivation: Responsibility:Other Test Subjects - Kit thinks she's one of "the lucky ones". From what she's learned about TG, she knows they've abducted dozens of test subjects over the years. Many who escaped during the event several years ago haven't assimilated to the outside world as well as Kit. Whenever possible, she assists them. And there are always the others - the unknown subjects still trapped in Tallow's secret labs.
Obsession: Tallow Genetics - Kit has made and squandered a couple small fortunes in her career as a cat burglar. Instead of spending her ill gotten gains on booze, drugs, gambling, and the other small vices that crooks are prone to, Kit has been spending her spare time and money tracking down any clue she can find about Tallow Genetics - especially the team responsible for her. She needs to know why she is like she is and what, if anything, she was before she was in TG's lab. So far she's found more red herrings and dead ends than decent leads, but that only peaks her curiosity.
Secret: Wanted Criminal - There aren't many career choices for a teenager with no documents, family, support network, or formal education. Kit started off shoplifting and picking pockets. She eventually met a "semi-retired" second story man who taught her the finer points of high end art theft. So far Kit's done a good job of avoiding the police and really needs to keep it that way.
