One more day and Lucifer is busted out! Before Supernatural season four ended in a fade to white light, remember that Dean Winchester (Jensen Ackles) started the dominoes falling once he tortured souls in hell and as a result beak the first seal binding Lucifer. With that lock picked, Lilith started on the next 64 seals. But it was our dear Sammy (Jared Padalecki), hepped up on blood and late-night creeping, who killed Lil to break the final seal holding Lucifer. Just before Dean ganked Ruby (Finally! Thank you Eric Kripke), she told Sam her boss would be grateful. Will Lucifer actually be happy to see Sam? And weirder, will Sam and Dean be happy to meet Lucifer?

Is ManBearPig (er, Lucifer) going to bring wrath and ruin, or smug? Maybe Lucifer’s tactics involve exploiting human pride and good intentions and blinding by rainbows.

The one thing we know for sure is that Metallicar cannot be corrupted by evil. Everyone else is fair game and ripe for temptation.

Supernatural returns with “Sympathy for the Devil” on The CW, on September 10, at 9pm EST/8 pm CST.
