Tanner's folks are still alive, not that it makes him happy to know it. They divorced when he was ten, and the marriage had already been deteriorating years before that. He spent a lot of his childhood, both before and after the divorce, used as a tool in their ongoing emotional warfare. Now that he's old enough to see some of that for what it is, he's deeply resentful, and incredibly bitter about the fact that he never had the chance to grow up in a loving family. :') Currently he lives with his dad, but they don't see each other much anymore.
EDIT: Sniped!
This guy's surname is Wang, which means 'king'. It's both a pun on his breed (Regal) and his character's status as an ultra-rich conglomerate heir. :U
Name a character who has impulse control problems.
