Dean and Bobby lock Sam in Bobby's panic room, in order to help him withdraw from the effects of the demon blood. Sam starts to hallucinate — first he imagines he is being tortured by Alastair. Next he is visited by his fourteen-year old self who accuses him of abandoning his hope of being normal, and brings up his guilt of Jess' death.
Meanwhile, Rufus Turner calls Bobby with news of more of the 66 Seals being broken. Bobby challenges Dean about whether they are doing the right thing, and whether they should let Sam go after Lilith to stop the Apocalypse.
Still in Bobby's panic room, Sam sees his mother, who says she understands what he is doing and gives him support.
Dean calls on Castiel, who tells Dean that Sam could kill Lilith, but that consuming that much demon blood would make him inhuman. Castiel says Dean can be the one to stop the Apocalypse, rather than Sam, and asks if Dean will do it. Dean agrees and swears fealty and obedience to God and the angels.
Sam starts experiencing more extreme symptoms — he is being flung around the panic room, so Dean and Bobby handcuff him to the bed. After they leave, Sam imagines Dean is taunting him and calling him a monster. At the same time the real Dean tells Bobby he would rather see Sam die than turn into a monster.
That night Castiel comes and uses his powers to release Sam's bonds and open the door to the panic room. Sam slips out, but is confronted by Bobby, who doesn't have the heart to shoot him. Sam knocks him out, steals a car and escapes.
Sam meets up with Ruby, and drinks more of her blood. Ruby tells Sam there are only two or three seals left to be broken. She says only "Lucifer's first" can break the final seal — and that is Lilith. This renews Sam's desire to kill Lilith. She says she has a lead on a demon close to Lilith, who is nearby.
As they prepare to leave, Dean arrives and tries to kill Ruby, but Sam stops him. Sam and Dean start to argue over what they should do, and things get more heated and bitter until Dean calls Sam a monster, and Sam hits him. They fight until Sam knocks Dean down and nearly strangles him.
As he turns to leave, Dean admonishes him with the same words John Winchester used so many years ago — that if Sam leaves, he should never come back.
