Not necessarily. Like I said, it's just something that ties you guys together. There's also the fact that all of you but Lydia (unless I'm forgetting something) have "died" on the show. Derek after the Alpha fight, the twins with the Darach, and you in the ice bath when they were looking for Erica and Boyd. There's also Lydia getting attacked by Peter and running off into the woods, which could potentially be her part. I don't know, though. This is all purely speculative.
