I'm working on bringing in the secondary pack alpha. He could have been a friend of Nick's before he was banished from the pack. The idea I had concerning Westin(the secondary pack alpha) and Sam's relationship was that it went beyond friendship. With Sam having been killed in the challenge for leadership of the Keystone pack, Westin holds Nick totally responsible for Sam's death, and would like nothing better then to see the alpha's head on a gold platter.
