I'm sure someone already pointed at it, but "I'll stand by you" from The Pretenders it's so much how Cas loves Dean.
"Oh, why you look so sad?
Tears are in your eyes
Come on and come to me now
Don't be ashamed to cry
Let me see you through
'Cause I've seen the dark side too
When the night falls on you
You don't know what to do
Nothing you confess
Could make me love you less
I'll stand by you
I'll stand by you
Won't let nobody hurt you
I'll stand by you"
That's just few lyrics but every single one of them fit so well, because it's unconditional love. He'll stand by his side, even if Dean murders the world.
"will lokius go canon this season?" thats the not the question here. It's marvel. I know they won't. But i want to see just how close they will get to it. How much will they get away with? How much of the story they want to tell will make it through?
Mary's "angels are watching over you" is a great line that makes full use of dramatic irony. We, the audience, know that having angels "watching over" you is NOT a good thing. So from our perspective "watching over" takes the meaning of "keeping under survellaince" and it's not pretty: it reminds us that angels are soldiers, they have a plan and a war to win. However, Mary doesn't know that when she says it, for her "watching over" means "protecting, taking care" and it's associated with the image of angels as guardians and protectors. What's even better is the fact tha later in the series, the show will strongly associate the "watching over" part with Castiel. And honestly? It works SO well 'cause the dramatic irony still works. Cas still doesn't incarnate the preconcevied notion of "guardian angel" and, at the same time, he stil sees himself as a solider. He shapes his own way of caring and protecting in a military fashion rather than a family-oriented one. It's not a "I'm here for you", more like "I'll go to battle so you won't have to". And this basically sums up the BIG issue he has in his relationship with Dean but that's for another story. Anyway, I'm just so fascinated with some lines in this show, I'll take the good ones when I can, lol!
