We have a followup to some Supernatural spoilers that supervising producer Sera Gamble hinted at last week.  We have updates on both Castiel's and Lilith's returning appearances.

Oh and if that's not enough for you, we have a sneak peak from Thursday's episode, "Afterschool Special" that shows a young Dean and Sam flashback:
