Abaddon finally gets something that she can use as leverage against Crowley to force him to lure the Winchesters. Meanwhile, Castiel rallies his forces and asks Sam and Dean to come in and help him interrogate a captive angel with ties to Metatron.

When Sam and Dean look into a murder at a museum, they learn a ghost from a merchant ship that sunk in 1723 may be at the heart of the mystery. After realizing “The Star” was the same ship that Crowley’s son Gavin McLeod should have been aboard, they enlist help from Rowena to track Gavin down. Kelly Kline, still pregnant with Lucifer’s child, takes refuge with a demon after an angel attempts to kill her.
