Bringing back a number of fan-favourite faces doesn't stop with ghosts as Kevin, Rowena, Ketch and Amara make a return, sadly to no great effect. Rowena and Ketch continue to be fun, entertaining characters with strong performances by Ruth Connell and David Haydn Jones respectively, and their chemistry makes their scenes together far better than they should be. Kevin's return though feels superfluous and in many ways wrecks the happy ending of his character arc in season 11, and Amara's return is the biggest waste of character potential that Supernatural has ever done. The episode's antagonist is a weak presence with no discernible USP to make him more of a threat than the typical Supernatural ghost, and the limited number of ghosts in the episode reeks of poor production values and gives the story a cheap feel overall. It's also very slow and tedious a lot of the time with no strong writing or direction to elevate its run and a weak ending that's contrived, poorly executed and thinks it's clever and special when it's actually been done hundreds of times before. One of Supernatural's weakest episodes ever.
