Destiel Fanfic If they really go back and think about it... it all started with a tree. A Christmas tree, that is. Castiel is human now, and the apocalypse is not only over, it's been averted. Sam's away at NYU, finally finishing law school, and Dean's stuck in what is probably the most awkward situation of his life. He's not exactly sure how he ended up sharing a flat with Cas in Media, Pennsylvania, but he does know the curious would-be angel is sort of derailing his plans for a life of decadence and booze. Cas is trying to make the best of his humanity by exploring human holidays. Dean can't exactly complain because he's pretty much the reason Cas got his wings clipped in the first place.
Dean didn't actually want to fall in love, but how was he supposed to know it would all start with a goddamn tree?
