First up on the TNT loop today: Deja vu! 10.04-- aka that werewolf one with the girl... blah blah blah... (no really, you wouldn’t believe how many people tell me this one’s on their “skip list.” Despite the fact Kate the werewolf from 8.04 is a straight-up Dean mirror...)
The callbacks to the current situation as of 13.03 are just ridiculous.
Sam and Dean have been on a little “vacation” from hunting, because Sam is SCARED of Dean’s powers (having just been cured of being a demon, and still bearing the Mark of Cain). Dean, meanwhile, just wants to feel “normal” and work a job, because it’s HIS normal.
They talk about how “dark” Sam went in the name of curing Dean, how he used a guy to summon a demon (and how that guy ended up dead by Dean’s hand because of it...), before Sam tortured said demon and killed her for info on Dean. Sam minimizes and pushes down the accusation, finally framing it as “I did what I had to” in order to save Dean.
Sam and Dean interview a witness (while wearing forest ranger uniforms) while sitting under the giant Panheads sign from the tattoo shop in 13.02. The guy had thought the monster also attacked a girl, who he later saw at an old abandoned barn and believed she was a ghost... but when Sam and Dean arrive they find a trail of dead chickens leading right to Kate the Werewolf.
They restrain her, question her believing she was the werewolf who killed the man at the bar, and are prepared to kill her... She is surprised by their accusations, but doesn’t resist. Dean points his gun at Kate, but Sam stops him, with “Let me do it.” Because Sam is still wary of Dean doing anything violent for fear it would “feed the mark.” He tells Dean flat out that he doesn’t think Dean’s “ready” for this. (Hello patronizing Mr. Judgypants! Dean doesn’t appreciate it...)
While they’re arguing about Dean’s “readiness” to hunt again, they get a call from the Sheriff that another body’s been found, that Kate couldn’t have killed because she was with them at the time... Meanwhile, Kate escapes. Sam can’t understand why she was so ready to sacrifice herself if she was innocent of the kills, and that leads them to Kate’s sister... who was dying when Kate chose to turn her into a werewolf. Unfortunately, her sister didn’t want to live by Kate’s rules, not killing humans, on the run. She wanted to use the power, to do whatever she wanted... as if she were invincible because of it.
And here’s where the Dean Parallel is strongest: Kate “proves” she’s innocent, because she carries a silver dagger with her that she intends to use on HERSELF if she ever “loses it” again. (Again, she was prepared to take herself out before she could hurt anyone else. Which is the whole “if I can’t save myself, I’ll kill myself” solution that Dean himself internalized back in s2, and has been living with ever since... that he’d most recently faced head-on in 9.10 when he’d thought he might need to kill Gadreel!Sam in order to stop him until Cas helped him find “a better way.”)
Dean LIES to Kate about having a werewolf cure in order to secure her cooperation in finding her sister. Kate would’ve otherwise sacrificed herself DESPITE what her sister was doing, hoping to give her sister a chance to escape. The thing she didn’t understand is that Sam and Dean wanted to stop the RIGHT monster, and like in 8.18, not just any monster will do.
Kate believes them about the non-existent cure, because she’s just so desperate to save her sister. They arrive to find that Tasha has turned two men into werewolves, trying to build her own pack. Tasha and Kate talk, Kate tells her it doesn’t have to be this way, that they can live peacefully without hurting people, but Tasha doesn’t want “to be saved.” She gives Kate an ultimatum, join her pack or walk away. Kate appears to relent, but when she hugs Tasha, she stabs her sister with her silver dagger and runs.
She did what she had to do... knowing that she’d never be able to “control” her sister. She couldn’t save her, so she had to kill her. And she made that horrible choice, but she was allowed to live.
Throughout the episode Sam tried to justify what he’d done in the name of saving Dean, and pressed Dean to talk about his time as a demon. He only backed off when Dean told him he was embarrassed by all of it, but he did justify that he’d done most of the worst things as a demon to people who “deserved” it. But Dean’s also confronting what the Mark might still be doing to him. Being cured of a demon only solved half his problems, and he could still wind up there again if he’s not careful. But locking himself up and doing nothing isn’t a solution...
DEAN Maybe I'm not ready to hunt.
[Camera pulls back to show the pain in Dean’s expression and the unshed tears in his eyes.]
DEAN [brokenly] But I am just trying to do the right thing, man, 'cause I'm so sick and tired of doing the wrong one.
As of 13.03, Dean may not be ready to hunt, but it’s what he does. It’s his way of doing the right thing, even if he’s just going through the motions right now. And just like Kate, who convinced Dean she was trustworthy by having been prepared to kill herself if she succumbed to the power. Dean could identify with the feeling, except for him at the time, killing himself would only lead to him waking up a demon again thanks to the Mark... He didn’t even have THAT as a comfort at the time.
Which is sort of the situation he’s in regarding Jack right now. From 13.02:
Dean: Okay, what the hell? Give me that. You -- Don't be an idiot. Look, A, this is not gonna do anything to you, okay? And B, you-- What the hell?
Jack: Exactly. What the hell am I? I can't control... whatever this is. I will hurt someone.
Dean: You know, my brother thinks you can be saved.
Jack: You don't believe that.
Dean: No, I don't.
Jack: So... if you're right?
Dean: If I'm right... and it comes to killing you... I'll be the one to do it.
They both know Dean literally has no idea how to even go about killing Jack... they have no weapon that can. Just like Dean back in 10.04, they literally had no weapon that could kill him that wouldn’t just make his whole situation even worse.
So right now, it’s a hollow sort of comfort, but to Dean... it really is a comfort... which he tells Jack while he’s concerned that he will accidentally hurt someone. To Dean, it’s supposed to be a relief to know that someone will be there to stop Jack from going darkside... especially when that was Jack’s immediate concern when Dean made that statement.
