As you can see from the promo, this girl claims to be the supernatural offspring of Dean, who has aged to maturity within three days of conception (The Vampire Diaries‘ Sara Canning guest stars as the mother). We are actually hoping that this girl sticks around – it would be a nice way to expand the show a little bit. But she’s most likely gonna die, don’t you think?

The stills were posted on SpoilerTV.
