Sam asks Lily if she'll still do the spell, but she says that wasn't the deal and she has to go. Dean yells at her - "He's OUR KID!" - and accuses her of losing so much of her soul that she's not even human anymore - if she was, she wouldn't be able to stand someone else feeling the pain of losing a child as she did. Lily stops - and changes her mind, agreeing to help them. Jack's body is placed on the table in the Library, and Dean prays to Cas to let him know they're ready, as Lily begins the spell. Jack suddenly sits up, Sam hands him the spell and tells him to read it. When he's done, his eyes flare as his soul reenters his body. Dean asks him how he feels. Jack says he feels good and they both hug him. Dean turns to thank Lily, and discover she has died.
Later in the kitchen, Sam, Dean, Cas, and Jack are having burgers and beer. Dean tells him how glad they are to have him back, and now that they will soon know where [[Michael]] is, things are starting to look up.
