That's totally cool. It was just an idea, and can easily be changed. If you imagined Sam having had a mate and child, maybe Westin can have been the brother to Sam's mate. It could be why he sided with Sam over Nick. I was going to have him have been an enforcer with the Keystone, before the battle for leadership of the Keystone pack happened. Westin was raised within the Keystone pack, so he most likely would have been friends with both Nick and Sam.
