Next, Sam and Dean head to the scene where they speak with a police officer that claims it was likely a 'bear attack' and says that Gwen is visibly upset and saying strange things. The brother's decide to visit Gwen, as she still believes that she is in danger. The camera effects show the hellhound entering Gwen's home behind Sam and Dean, making this scene very intense to watch. Sam tells Gwen that Marcus was indeed attacked by a bear, hoping that this will help her to move on with her life. However, Gwen, who feels belittled by this statement, responds by telling the brothers to leave. Several minutes later, the hellhound attacks Gwen, but Dean bursts in and shoots at it before it can harm her. Unfortunately, the hellhound escapes through the window.
Sam and Dean then explain to Gwen that they are hunters of the supernatural. As hellhounds only attack those that have sold their souls to a crossroads demon, they begin questioning her. Gwen is adamant that neither her or Marcus made any sort of deal with a demon. This leads the brother's to call upon Crowley for help.
Crowley, who is busy gloating at having Lucifer locked up in Hell, quickly comes to pay Sam and Dean a visit when he discovers that one of his hellhounds has escaped. Crowley tells Sam and Dean that the hellhound isn't just any hellhound- it's Ramsey, the first hellhound ever created, who heels only to Lucifer himself. Ramsey is likely still after Gwen because she fought back with the ax when it attacked her and Marcus.
The boys take Gwen back to the woods where she was camping, in order to hunt Ramsey down. They explain that in order to see a hellhound one either has to have either sold their soul to a demon or be wearing glasses covered in holy fire. Dean agrees to partner up with Crowley and search the woods, while Sam and Gwen ride in the Impala to keep Ramsey off her trail. What follows is an insightful conversation between Dean and Crowley about their alliance. It was especially funny to see Dean once again express concern over 'Baby' being damaged:
DEAN: Take care of her.
SAM: Of course. Even if Ramsey circles back, as long as we keep moving, Gwen's going to be- oh, you're talking about the car.
DEAN: You tend to ride the brakes.Sure enough, Dean's concerns are warranted, as Ramsey attacks Sam and Gwen when they pull off to the curb, damaging the hood of the Impala. Sam quickly gets his weapon and tussles with the hellhound, but loses his glasses in the process. Gwen comes to his aid, by hitting Ramsey over the head, however, as Sam still doesn't have his glasses, he is unable to see where the hound is. Paying careful attention to the mist around them, Sam is able to make out the movements of the hound, and lunges with his knife, killing the beast. This is Sam's second major kill this season, right after the Alpha Vampire.
Meanwhile, Castiel is hot on the trail of Kelly Kline. He begins by investigating the diner where the two angels were killed. He speaks with the paranoid manager, who firmly believes that it was the work of 'reptilian aliens'. This scene reminded me of the one in season 2, between the brother's and Ronald, who claims that the robbery's are the work of a 'Mandroid'. When the manager senses that Castiel is doubtful, he puts on the surveillance tapes showing Dagon killing the two angels that were after Kelly. This sparks Castiel's interest as he sees the characteristic 'yellow eyes' of a Prince of Hell.
When Castiel leaves the diner he runs into Kelvin, an angel who is also tracking Kelly Kline. Kelvin tells Castiel that if he is able to assassinate Lucifer's unborn son, he can earn a place in Heaven again. Castiel seems unsure that the angels will welcome him back, but Kelvin explains that with Joshua in charge he is certain that Castiel can have redemption. He then takes him to the portal to Heaven, so that he can speak with the other angels about their mission.
As Crowley is gone helping the Winchester's track down Ramsey, two low-level demons discover Lucifer, who is currently chained up in Hell. The two demons reveal that they let Ramsey loose to provide Crowley with a distraction. They tell Lucifer that they don't like Crowley's rule and want to "make hell great again." They then release Lucifer after he has agreed to their terms, but Lucifer immediately smites them. When Crowley returns after Ramsey is killed, he discovers Lucifer sitting on the throne in Hell. After throwing Crowley across the room, Lucifer shows his angel wings as a display of power. However, Crowley still has a couple of tricks up his sleeve. He snaps his fingers and Lucifer's wings suddenly disappear. Crowley tells Lucifer that he has warded Nick's vessel with runes and spellwork from the Cage and as such Nick's vessel is essentially a prison. He tells Lucifer:
I'm glad you had a little taste of freedom. What I said was...I'm always 10 steps ahead. I said you cross me, I crush you. You hit me, I hit you back twice as hard. You make me your dog, I'll make you my slave.I have to say, this was a totally unpredictable outcome. I well expected Lucifer to easily escape from Crowley's grip and take over hell. However, I was glad to see Crowley once again demonstrating how cunning and intelligent he can be- especially when it comes to attaining revenge. It is always nice to see the visual effect of the angel wings.
After Sam and Dean return from saving Gwen, Sam's phone once again begins vibrating with a call from Mick. When Dean asks if it is his formula giving them another case, Sam comes clean about working with the BMOL. I expected Sam to continue to lie to his brother, so this was a pleasant surprise. I was glad to see that Sam and Dean are continuing to be honest with each other, which has only been a recent development since Season 11. This felt like another step in the right direction with their relationship. Dean makes Sam promise that they will immediately stop working with the BMOL as soon as anything feels 'off' . He explains that he definitely doesn't trust the BMOL, but he is forced to work with those he doesn't trust all the time. Dean does have a point about the Winchester's having to work with those they don't necessarily like. It may be noted that the animosity between the Winchester's and the BMOL is more personal, as at the beginning of Season 12, the rogue agent Toni Bevel was responsible for kidnapping and torturing Sam.
However, in the past we have in-fact seen Sam and Dean partner with equally unlikely adversaries. Dean references his own partnership with Crowley. We first meet Crowley in Season 3, when Bela Talbot hands him the Colt. Crowley has aided the Winchester's in many ways, but also thwarted many of their plans once an opportunity presented itself. Crowley's recent actions in Season 12 suggest that this one-sided relationship with the Winchester's is beginning to evolve. Crowley had no reason to save Castiel by breaking the Lance of Michael. Even as he speaks with Dean about this, his reason's for saving Castiel are hazy at best. Crowley insists he only helped Castiel, "just to save myself the Winchester man-pain and you lot moping about like a bunch of school-girls."
DEAN: A few years ago, who would have thought you'd be helping us save the girl of the week?
CROWLEY: Or, a few years ago, who would have thought you'd be working with the King of Hell. Maybe you've rubbed off on me, or, maybe I've rubbed off all over you.Crowley's actions are definitely proving him to be a reliable partner to the Winchester's. His role in helping the brother's is finally recognized as Sam and Dean both tell him 'thank you' for the help that he has provided them. This seems to make Crowley uncomfortable, and he vanishes immediately after.
The scene between Gwen and Sam in the Impala, where Gwen talks about how she feels responsible for Marcus's death, felt pointless. Gwen vaguely states that it was all her fault and that she "should have told Marcus". I was expecting this statement to be explained later, and was disappointed when it wasn't. I suppose Gwen's guilt was purposely portrayed as misplaced, and this scene was meant to draw a parallel to Sam's own situation with losing Jessica. However, even Sam's own response to Gwen's statements was unrealistic, as he provided her with no reassurance that she didn't play any role in her boyfriend's death. Perhaps, like the rest of the audience, Sam was wondering what exactly Gwen was talking about.
I was disappointed to see Castiel partnering with Kelvin and neglecting to tell the Winchester's he was doing so. I felt that this was a hint at Castiel once again being led down the wrong path in the belief that he is doing good. I'm not sure if Castiel will be able to carry through with assassinating a woman's child. While Dagon isn't exactly a demon I think we can trust, I do think that she was right about the role of upbringing in determining the character of an individual. It will be interesting to see how the partnership between Castiel, Kelvin, and the other angels will play out.

Sadly, Supernatural goes on hiatus for the next several weeks, with episode 16 "Lady's Drink Free" airing on March 30th.
