The only problem is that Jeff wouldn't introduce a character in the series that isn't directly connected to one of the main characters (i.e the alpha of season 1 was peter hale (dereks uncle), The kanima was jackson, the nogitsune was stiles and the oni mastor was noshiro, and the benefactor was meredith). All of the people who caused conflict who we didn't know until midway thru each season turned out to be people who were introduced at some point during that season or a previous one. I doubt that it could be anyone but mason because the list of characters is so short and mason is never around, seen or mentioned when the beast appears. They were also quick to emphasize the fact that they could have overlooked someone on that list or the list could have been incomplete. Also adding there might have been something no one considered that would make someone a genetic chimera. To me its still pointing to mason.
