How will you describe Sam and Dean's changes throughout the seasons?

Huge!Even though one word would probably do if you compare them now to first season. they have both grown physically and pagganap experience.

Something else for your project? I'll try to help.

Um... well, Dean's grown in that he isn't quite as bossy or cocky anymore. I think he's basically just broken, disappointed, sorrowful. He misses John, he misses Sam the way he used to be, he needs someone and he's madami willing to admit he needs someone, and because of that, he's opening up a little madami to some outside people (Bobby, Lisa, Cas).

Sam- I dunno whether he's moved pasulong or backward. Ignoring this season (because to me, without a soul, he can't possibly qualify as Sam), he's still changed quite a bit. He's a little madami secretive, but he's not as naive. He's stronger than he was, but I think he's a little madami cocky, too.

Um... I guess I was a little harsh on both of them. Didn't mean to be, but the last couple of seasons got me pissed. Hope I helped, at least a little!

well Dean kinda stayed the same he just got really sad over the years - asking him self why the do i get up in moring

but Sam kind of stayed the same in first 3 seasons - but after season 4 he just became a new person - Ruby made him this new person that has blood problums - cant OD - or Dean will put him back in the panic room - when finding out about lusifer - now hes soulless - Sam has changed so much - but i so pag-ibig it
