We open in black and white at the bunker in the past, where we meet Jenkins, a young man, and Haggerty, an older man, who are both men of letters. A women, Dorothy, arrives with a witch and they all start interrogating her. Are we in Oz? In present day at the bunker, Sam has figured out that they may be able to track where all the angels landed by figuring out how to rewire an incredibly old computer that Sam found. Sam and Dean head to look at it, but can't figure it out, so Dean calls Charlie, Charlie arrives at the bunker and starts working on the computer. Charlie gets everything in order and we find out that she has been hunting, on her own. Back in the past, we see the witch escape her binds and head to the computer room, Dorothy goes after her.
In present day, they head back down to the computer room, and see this web like thing on the wall, it contains Dorothy. Dorothy awakens and we find out she made a spell that contained both her and the witch, which means the witch is now loose in the bunker. The witch finds Crowley and he helps her, figuring that the witch would find her way to Crowley, Sam and Dean head there next and he tells them that she is looking for a key. Since Oz is real, Charlie starts going over what she learned in the books, and makes bullets out of poppy. The key opens the door to Oz, Dean tells them that he's seen the key and that it's in his room, him and Charlie go to find it. When Dean finds the key, the witch appears and grabs the key, and in the process Charlie gets zapped and dies.
Dean manages to get Ezekiel to revive Charlie, Dorothy comes in to stay with Charlie while Sam and Dean go looking for the witch. Dorothy tells Charlie that her dad wrote the Oz books, and Charlie tells her that he left her clues in the books, they then head to the garage where Dorothy left her motorcycle. In the motorcycle bag Dorothy pulls out the weapon that will kill the witch, the red shoes! Dean and Sam find the witch, but the witch ends up putting both Sam and Dean under a spell to make them hunt down Charlie and Dorothy. Dorothy and Charlie each take one of the red shoes when Sam and Dean arrive, Charlie escapes to go find the witch, while Dorothy is left to handle Sam and Dean.
The witch opens the door to Oz and we see the flying monkey's heading for the door, when Charlie appears and stabs her with the shoes and kills the witch. Later on Charlie and Dorothy are leaving when Dorothy invites Charlie to come back to Oz with her and Charlie accepts. Charlie and Dorothy then open the door to Oz and head into Oz.
Great episode! Always nice to see Charlie, and I hope to see her again one day! Plus the fact that Oz is a real thing was awesome, as that was my favorite movie growing up. Next week looks interesting since Deans going to be a dog, can't wait to see how that plays out!
