Short Description The CW
Below is the recap of this episode, which may contain spoilers if you have not seen it yet!
Sam, Dean and Bobby are still at the laboratory where Castiel had swallowed all the souls from purgatory. Demanding to bow before him or being destroyed all three bow down but Castiel stops them realising that bowing down without meaning it means nothing and that they fear him and not love or respect him. Yet Castiel does not kill them. Once they were his favourite pets before they had turned on him. Now, being the new god, he doubts that the three will turn against him again. Castiel promises them if they live to his rules they may stay in his kingdom. Should they rise up on the other hand he will kill them.
Although Castiel had promised to fix Sam's broken wall he refuses to do so now because Dean had not stayed down as he had promised. All pleading from Dean's side does not help. Castiel vanishes and leaves Dean and Bobby to deal with Sam on their own.
Back at heaven Castiel punishes the angels who had followed Raphael by killing them all. The rest must obey to him. Once Castiel believed in free will but now he is convinced that both the angels and the humans need a firm hand and a new father, a new god. Castiel proclaims it being a new day on earth and in heaven.
Back at Bobby's Dean does what he always does when being left helpless - he fixes the Impala. Sam is recuperating and Bobby is looking for any signs of Castiel's whereabouts. Both have no clue how to deal with the situation. When Sam wakes up he tells Dean that he thinks he is okay. But he is not. He has a feeling of being followed by someone. By who he does not know and he does not tell Dean.
A small community church is the place Castiel picks to show his new powers. During mass the priest tells his community that someone has to speak for god in this new world made of media, money and Lady Gagas. Castiel tells him that he has a problem with hypocrites like him. And he who lies in my name shall choke on his false tongue and his poisonous words. Castiel kills the priest but having done that he hears someone calling his name in his mind and the church window morphing the former portrayal of a holy figure into the portrayal of Castiel.
Back at Bobby's Sam still has the feeling of being followed by someone. And the someone manifests into hallucinations of his time being in hell throwing images at him. Sam gets drawn out by Bobby who fetches him because he thinks they have found a lead on Castiel. The news reporting the sudden death of nearly 200 religious leaders and eye witnesses describing to have seen a very young god wearing a raincoat. The news about acts of god continue from there on. Sam suggests to talk to Castiel but Dean says no. One does not get in the way when god becomes righteous.
At a camping ground in Tennessee Crowley is hiding in a motor home following the news about miracles happening around the world as well. The interior is all angel proof but nonetheless Castiel is no longer an angel and finds him. Despite Crowley thinking Castiel wants to kill him, he does not. Castiel has plans for him. He wants Crowley to become what he was before: the king of hell. The only difference now would be that Castiel chooses what souls Crowley gets. Castiel needs a threat to hold over his enemies and he thinks Crowley would be perfect at that and also to keep Michael in Lucifer's cage. Crowley accepts.
Back at Bobby's Sam is once more plagued by hallucinations and getting more terrified by the minute calling for his brother Dean and Bobby. To Bobby it is a miracle that Sam is even up and running and that back at the laboratory it was pure adrenaline that kept Sam going. But now he is not quite sure. Dean desperately wants to believe that Sam told him the truth and that he is alright but on the other hand he also knows that they could never catch their breath before and he is sure that Sam is hiding something from him. Their talk is interrupted by Sam arriving who had heard the latter part. Sam informs Dean and Bobby that more and more deaths are being reported in the news and that they had to do something.
Sam believes that there must be some weapon being able to kill Castiel, but Dean believes that Castiel has truly become god. There is not a thing that can kill him but that there might be someone. Performing a ritual they summon Crowley. Crowley is not pleased being afraid that his new boss would kill him for even talking to the Winchesters let alone conspire against him. Dean wants a spell from Crowley, a spell on how to bind Death because Death is the only one who can kill Castiel, having told Dean once that he also had reaped god before.
Castiel believes he is a just god, that he only punishes liars and those who forsake him and heals a blind man from his blindness because he is a true believer. But Castiel's bodily hull starts to suffer being god. It seems to start melting. The caught-up souls from purgatory in his body want to be let out.
Back at Bobby's the guys receive the spell they had wanted from Crowley in the mail. In order to execute the binding of Death they need an act of god crystallised forever. They need a Fulgurite and find one big enough at a family who had bid and won one off an internet auction site. Breaking into the family house they find the Fulgurite and perform the ritual to bind Death right there. Death is not very pleased having been summoned and bound like that despite Dean's offering of fried pickled chips and a milk shake to soothe him. Death assumes Dean had called him because of Sam's hallucinations and is surprised when Dean suggests to him to kill god instead.
Right in the middle of their talk to Death Castiel appears. He is furious about Dean having once more turned his back on him. Right when he wants to kill Dean, Dean reveals to Castiel that Death is bound to him now and has to carry out his orders. Death also reveals that the new god looks more like a mutilated angel than a god. He also tells Castiel that there are older things in purgatory than the souls Castiel had swallowed and that he had swallowed those old things as well. Castiel claims that they were no problem and that he had full control over them.
Wanting to know what older things Death is talking about Death explains to Dean that long before god had created angels and men he created the first beasts - the Leviathans. Those Leviathans were so fearful that god had decided to lock them away before they could destroy everything. That was why god had created purgatory. Death also challenges Castiel. Despite thinking he is god Death tells him that he knows god and that Castiel was only a little soldiers with a revenge act. That he was no god. Dean begs Death to kill Castiel now but all what Castiel does is to snip Death's bindings away and to vanish.
Death advises Dean to have Castiel returning those souls and the Leviathans back to purgatory and quickly. He also tells them that they already have everything they need at that lab and that he would make another eclipse so that the door would open again at 3:59 am Saturday morning just before dawn.
Meanwhile Castiel reappears at a senator's campaign head quarter telling himself that he is not petty and that he is only punishing a woman abusing her power. But the evil things within his body take over. When he wakes up he finds everyone in the head quarter has been killed by him and realises that Death was right about him being not god and the Leviathans in his body starting to take over.
Back at Bobby's Dean resigns to doing nothing. Having been disappointed so many times he is not even mad at Sam for not telling him about the hallucinations. Sam desperately wants to convince Dean that Castiel is still somewhere in that body and that he has the hallucinations under control - to no avail. Sam resorts to the only thing he can think of. He calls Castiel as he used to do in the past offering his help to him. And Castiel shows wanting the help Sam had offered.
Back at the lab Castiel instructs Sam what he needs to open purgatory once again and sends him to get a certain jar with blood. He also apologises to Dean about what he did to him and Sam and that he would fix Sam if he was strong enough. Picking up the jar with blood Sam is once more plagued by hallucinations. This time Lucifer himself shows up claiming that Sam was still in the pit and that he never had left. That all was only a dream, the best torture Lucifer could think of doing to Sam. Sam tries to control it, tries to convince himself that the Lucifer standing in front of him is not real. But he fails miserably.
When Sam does not return to the lab, Dean goes looking for him but only finds the jar with the blood. With time running out he returns without Sam to perform the ritual that opens up purgatory. The door opens and the souls in Castiel's body return to purgatory. For a brief moment Castiel returns to being his old self thanking Dean and Bobby for their help and the promise to redeem himself. Then he sends both away because the Leviathans held on to his body not returning and which are now taking over and making Castiel the new enemy to the world.
