16 parts Complete Dean Winchester has known his entire life that domesticity isn't in the cards for him. He's poison and anyone brought into his life is marked for death from the beginning. With Thea, however, neither of them had a choice. No those angel bastards are once again taking choices away from him and no matter how hard he's falling for her, he knows he can't be with her. And Thea? Well, she's just desperate to show Dean that he does deserve to be loved, no matter how determined he is to hate himself.
As the apocalypse gets closer and her life is threatened more, Thea wonders if she's cut out for all of this, but she's no quitter, and no matter how bad the pain is, she's not giving up on him. Maybe that's why they chose her. Maybe they know that Thea is the only one who can save Dean Winchester from himself. And maybe in the process, he can save her from her own demons too.
