Aunt Jenna lives! Sort of!

Supernatural will not return with a new episode until February 3, but when it does, a former CW favorite will at least grace our small screens once again: Sara Canning (The Vampire Diaries) guest stars on "The Slice Girls" as Lydia, a woman who meets Dean at a local bar and takes him back to her place. Ooohhh yeah?!? Or, uh-oh?

Watch the official CW preview now and get an idea of the ramifications for yourself:

Elsewhere on the episode, look for Sam to make a discovery related to the case of a victim's heads and feet being severed. That really has got to hurt.
