Even after years of battling the unknown, Sam and Dean are still really bad at, well, not knowing things — at least when it comes to someone they care about. And considering that Amara has her hands on Lucifer — who’s still in Castiel’s body – it’s no wonder why Dean is losing sleep.
In an exclusive Supernatural sneak peek, Sam and Dean try to figure out what Amara wants with Cas when Sam proposes another idea: They should distract themselves with a case (which involves green eyes?).
Supernatural airs Wednesdays at 9 p.m. ET on The CW.
