She is then confronted by Hilda, who is disappointed in Sabrina because she did the one thing that Hilda asked her not to do. Sabrina recalls what Roz said about a baby crying and Tommy being lost in a foggy woods. She surmises that he's in Mortal Limbo — it's where the souls of unbaptized babies go when they perish, or the souls of people who died before their time. Sabrina simply needs to retrieve Tommy's soul. Sabrina asks Hilda if she'll help her find Tommy's soul to put back in his body. Hilda tells her that there are two limbos and that it's impossible for witches to cross over into mortal limbo. Sabrina replies that she can cross over as she's half-mortal. Hilda says that it's too late as Agatha is getting sicker and sicker because the Grim Reaper is expecting a body and her suffering won't end until the balance is restored. Ambrose interrupts their conversation and tells them that they need to see something in the embalming room.

Sabrina returns home to find her family waiting for her. Zelda is enraged at Sabrina's actions. She also asks how Sabrina knew what spell to use as Ambrose told her that he didn't give it to her. Sabrina admits she took a Book of the Dead from Ms. Wardwell's office, to which Zelda retorts "Oh so you're a thief as well as a murderer!" She tells Sabrina that she's going to fix this but Sabrina is still adamant about crossing over into mortal limbo and retrieving Tommy's soul. Zelda refuses to allow Sabrina to go to mortal limbo as she doesn't possess the power to do so. Also enraged that her family's attempts to prevent her from saving Tommy, Sabrina exclaims that Zelda isn't her mother and tells her to sop acting like it.

Back at the mortuary, Hilda catches Zelda punishing herself. Zelda regrets having taken Sabrina in. She wishes they let Diana's family have her. She recalls how much Sabrina looked like Edward back then and couldn't fathom giving her up.
Father Blackwood charges Prudence and Dorcas with killing Tommy because he doesn't trust that Zelda will do it. Every moment that he is live is another moment their existence is at risk. Nick overhears this and follows them. Prudence and Dorcas go to Harvey's house but Nick stops them by driving stakes through their footprints. He explains that it's an old witch catching spell to prevent them from moving. Prudence and Dorcas cry out for help. Nick says that they are going to stay put until the Spellman fix their mistake.
Sabrina and Madam Satan arrive at the door to mortal limbo. Madam Satan wraps a string around Sabrina's wrist in order to keep track of her. Sabrina recites the words and steps through the portal. Sabrina wanders through the fog aimlessly, calling out to Tommy without response. While there, Sabrina meets her mother. Diana can not believe it. She says "They took my baby after the baptism." and "The witches are coming." As the soul-eater approaches, Diana tells Sabrina to run. Sabrina runs and bumps into Tommy. She grabs his hand and tells him that they must leave now. Sabrina calls out for Ms. Wardwell and tugs on the string but it breaks. Sabrina quickly casts a spell and the portal opens: Hear me, Spirits of the Dead, and reveal the portal! Help me to pass through with this brave mortal! She and Tommy run through it. Sabrina makes it to the other side but the soul eater grabs Tommy before he can make it out. Madam Satan tells Sabrina that there is one other path she can follow. She can tell Harvey the truth. Sabrina walks off to go tell him. Madam Satan praises Satan that, finally, Sabrina's strongest tie to the mortal world will be severed.

They questions what being a witch means and if Sabrina could be dangerous.
Sabrina goes to the Kinkle house and reveals that she's a witch and that she resurrected Tommy. Harvey recalls Sabrina telling him this before. Just before her 16th Birthday. But then she made him forget with a spell. She even reveals to him that he comes from a family of witch hunters. Lastly, she tells Harvey that the Tommy he knew is dead and that the man in his house is merely a shell of his former self. Harvey asks why she did this to him. Sabrina explains that she was simply trying to help. She wanted him to stop hurting but she sees the error in her ways and now must put Tommy back where he belongs. Harvey asks if it'll hurt him. Sabrina doesn't think it will as he doesn't feel the same way they do. Given that Tommy is his brother, Harvey takes on the responsibility and asks Sabrina to leave as he doesn't want to talk to her. Once Sabrina is gone, Harvey grabs one of his father's hunting guns. As Sabrina walks away from the house, she hears the gunshot.
