I'd like to see some women who aren't over-sexualized, like Jo and Ellen...I thought Charlie would stick around and I was hoping she would since they closed the door for an opportunity of a sexual relationship between Dean or Sam when she revealed she was a lesbian..they've slept with enough girls :)

would love to see some old faces, but also some new ones, but not too much of both ;)

^ yep, a mix of both to create a nice balance

the only character I would love to see back is bobby ... even if it's just for one episode!

I hope to see some of the monsters that theyve killed off in purgatory but i'd also like to see some new characters and catch up with some of the old.

Both really.

a mix of both would be good but i would not mind see some old ones getting revived

BALTHAZAR!

A mix of both would be good. I agree with lucy - some strong females would be cool too!

I miss Jo and Bella!

GABRIEL!!!!!!!!!!!
And Bela, Balthazar, Ghostfacers, Ruby

I think it would be cool if they brought Ruby back for just one episode...so Dean and Sam could beat her up and kill her ass again! Hate her so much...I would like to see Jo back, Ash, Ellen, Michael(he's still stuck in the cage!), Adam(also still stuck in the cage -_-) Gabriel, and Balthazar. I don't really want any of these people to come back permanently, but I just want to see them again. They could be ghosts, or flashbacks or something? I just miss them all so much D': just for one episode to see them all again. Oh and John too.
