Aa the boys and Mary discuss that Lucifer is back, Sam mentions they will need Rowena, since she's the one who can put him back in his cage. He tries to call her, but Lucifer answers her phone. Sam's breath catches and Dean asks what, leading to Sam putting Lucifer on speakerphone. He monologues about how he's dispatched Rowena. When Lucifer asks if they know where Castiel is, Sam tells him to, "go to hell." Lucifer continues to go on about how he's indestructible and the boys can't beat him, then hangs up.
