SPN: thoughts on the characters in general

I finally got around to watch the end of season 1 (which was abso-fuckin'-lutely gripping and exciting and mean, and omg, Dean was so awesome) and somehow, my mind is full with thoughts on the characters, their relationships and the way they're depicted in the show.

So here a little huge rambling. I don't know whether it makes any sense, but it needed to get out.

( Cut due to length )

ETA: OH. MY. GOD. I just watched the first episode of season 2 and I'm fucking bawling like a baby. The ending of season 1 is just "WTF?!", but this, this is breaking my heart. *goes back to crying and watching ep 2*
