Well, the age range for the werewolves are from 124 - 28.  None of them are related.  I know that Sin's character met Tevan's after he graduated from college... So, I think your guess is as good as mine.  Perhaps talk to Question about it?  Since your characters are together.<br/><br/>EDIT:  I just had an idea.  If you want to be found during the game, instead of starting out with the pack... You could be someone that was friends with the sisters' grandmother.  And you were watching the house essentially, until the four woman got there.
