In the season 4 finale, Lucifer Rising, the title held true to the episode. We found out what some or maybe most thought all along that Ruby really was evil. All of season 4 Ruby fed Sam her blood to make his abilities stronger. Sam and Dean tried to prevent the sixty-six seals from being broken. Sam took off with Ruby to find Lilith. Sam thinks that by killing her he would stop the apocalypse but Ruby knew otherwise. Castile helps Dean get to Sam to try to stop him from killing Lilith. But Dean is too late and Sam kills Lilith and her blood brings forth Lucifer.

Season 5, which is supposed to be the finale season if Eric Kripke has his way, starts where the season 4 finale left off. They are still at the convent and Lucifer is rising. They try to escape but can’t. There is a bright light and then Sam and Dean are on an airplane. The pilot comes on to say they are almost there when a bright light shoots from the ground and they look to be crashing. Then we see Dean and Sam in a car and every station on the radio has bad news.

They go to look for Castile and they go to the writer, Chuck’s, house since that is where he last was. They find blood everywhere but they find Chuck still alive. He says that Castile is dead that the Zachariah and the other ark angels disintegrated him.

The angel shows up for Dean saying it is his time now to kill the devil. Dean, of course, is fighting it. But, the angel says that now is the time before Lucifer finds his vessel. Dean used a spell that he learned from Castile to get rid of him.

Dean and Sam are in the hotel room packing up. Sam gives him a hex bad that he made that he learned from Ruby. Sam starts to tell Dean how he knows that he can’t do anything to make this right, he knows that.

It then goes to Pine Creek, Delaware to a man walking down the street. He is heading home and things start go weird around him till it builds up with the wind and a gate opening and shutting over and over and it blocks. Then the man wakes up in what he believes is a bloody bed but when he turns on the light there is nothing there. He tries to go back to bed and rolls over to see a woman with blood splatters on her face telling him that he is the chosen one.

We then see a girl trying to write stories like Chuck about Sam and Dean. He comes through on the web to talk to her saying he needs her help. He wants her to get a message to Sam and Dean. Chuck had a vision that the sword of Michael is on earth and forty two dogs.

We then see Bobby show up. Bobby tells them that Michael was powerful and that if they could find the sword then they should be able to defeat the devil. Sam tells Bobby that it was his fault that the seal was broken and that Lucifer is here. Bobby had no idea and tells Sam that if they some how full this off that he was to lose his phone number. Sam takes some of the books and goes somewhere else to read.

Bobby tells Dean that maybe John was right. That maybe they did have to kill Sam to keep everyone safe. That reminds Dean of something of his father. He pulls out a card that says ‘Castle on a hill with forty two dogs’. He says it has to be where they will find the sword. Bobby says it sounds right and he then punches Dean through a wall and his eyes go black.

We come back form commercial to see Bobby still going after Dean and then a girl and a guy show up. They girl turns out to be Meg from a while back. Meg gives Bobby a knife to kill Dean. He gets Dean against the wall and his eyes change back to normal and Bobby stabs himself to kill the demon. Sam shows up to help in the fight and Meg leaves the girl she had possessed.

It goes back to the guy in Delaware and he is looking through some baby things. He digs out a baby monitor because he can hear a baby crying through it but when he goes upstairs to the baby room there is no baby. He starts to see blood pour over the sides of the crib but really all that is there is a blue blanket on the crib.

Sam and Dean get Bobby to the hospital and then they go to Castle Storage to see what their father has their. When they open it up they find three bodies and some angels. The angel shows them were the sword was. He says that Dean is the Michael sword. That he is Michael’s weapon, he’s Michael’s vessel. The angel breaks Sam leg to show that he is not playing around.

The angel tells Dean that Michael is the one to defeat Satan. If he says no that he will hurt Bobby further or give him stage 4 stomach cancer it then moves to Sam having no lungs. Castile shows up and kills the angels that showed up with Zachariah. Castile says he knows it wasn’t angels that saved him or Sam and Dean. He tells Zachariah to put the boys back together and leave. Castile carved in their ribs a way to hide them from the angels. Sam and Dean ask how he’s back if he had died and then he disappears.

It goes back to the man in Delaware and he sees the woman from before and she tells him that she is an angel named Lucifer. He says to remind him to quick drinking. She says that she needs to take control of his mind and body because he has been chosen to be a vessel. She has to convince him that he isn’t asleep and to invite him in. She tells him that God doesn’t care since he let someone come into his house and kill his wife and child. She tells him that she can give him justice. He thinks about the blood and the baby items and then invites him in.

Sam and Dean are with Bobby in the hospital. Dean says that this war isn’t the angels it is theirs. They will find a way to win. Bobby tells Sam before he leaves that what he had told him before was the demon talking, that he ain’t cutting him out of his life. Once outside Dean says that what he said inside was for Bobby’s benefit. He knows they will fight but he can’t guarantee anything. He also tells Sam that things won’t be the same again. That he tried to help him but he chose a demon over him. Dean tells Sam that he is having a hard time forgiving and forgetting and that there really isn’t anything Sam can do about it. Dean tells Sam that he can’t trust him now.
