What's going on with Sammy in season 6? stil being Lucifer 또는 What?

I'm quite sure that he literally does not have a soul. I think it's Sam, but his soul isn't in his body..

i'm thinking it's either Lucifer 또는 a different demon like Azazel he's always been after Sam & Ruby has come back from hell after she was killed in S3 so I say anything is possible. I hope it ends soon I don't like this Sam how he just stood 의해 & did nothing when Dean was attacked 의해 the vampire it's just not our Sam.

I'm sure this isn't a real Sam! I don't like how cold-hearted he is in this season. I want to bring my sweetie Sam back!

Well i think that Lucifer may still be a part of Sam? 또는 maybe he sold his soul.... but then Bobby sold his soul and he was still very emotional. But maybe Sam sold his soul to an angel? Hmmmmm I dont know......

I don't think he's Lucifer, 또는 possessed 의해 him.
Maybe he's being controlled 의해 something?
But I'm guessing he was brought back for the same reason Samuel was...

I miss Sammy, the way he used to be!

Remember at the end of s5 when sam took back control of his body when lucifer was possessing him and jumped in the hole what if lucifer is still trapped in his body and all that negativity is making sam the way he is now
