not a lot of new info but adding this here anyway:

off of the radio blog found here:

Summary for those not wanting to listen to the blog (it's rather long)...from tumblr (credit to windycitygirl89):

Will be in Episode 3.15 (Mentioned that it will be airing sometime in early February)

Playing a known killer named William Barrow, which implies that he has a history of being a killer and might be something of serial killer. We will find out what type of person he is after (Might be supernatural types given the title of the show) and whether or not he likes to kill.

Character’s appearance on the show is to basically facilitate and push forward the storyline of one of the series regular characters on the show (Couldn’t reveal whether the character was male or female or who it is, but he confirmed in an earlier interview that it’s not Tyler). We have something to learn about them and go oh my goodness about that person by his appearance and what he uncovers about that person on the show. (x - 30:40-32:40)

if it's not Derek I'm wondering if it will either be Chris or Peter...I know we get a Chris flashback. Also with the item Derek went to retreive and them making it sound like he and Peter might be investigating some Hale family mystery it could be either of them but he already said it wasn't Derek so maybe Peter.
