Crazy Theory 2 Sam's Odd Behavior

Sam's odd behavior has many wondering is it really Sam?

       It's very understandable why many would question if it is really Sam and not something pretending to be him ever since the season began Sam has been acting cold and distant.  But it's not just his coldness or the fact that he is distant that has some questioning is that really Sam. In the latest episode of Supernatural "The Third Man" Sam payed for sex which had many doing a double take to make sure that what they saw wasn't something that they were imaging. After many seasons of watching Supernatural we all know that Sam "doesn't pay" so to see Sam doing just that threw us all for a loop. 

     Sam didn't even objected to Cas causing a kid physical pain to get information on who had taken God's weapons. In a situation like this Sam would have objected and ask Cas to find another way that wouldn't cause the kid pain but not this new Sam.

        One could conclude that from the looks of the first three episodes that Sam acting odd is Sam not actually being Sam or him not being all there. However, I believe that he is emotionally damage and detach that he would rather bury his emotions so deep inside that he doesn't have to deal with what happen. Which is why I think that Sam paying for sex is a way for him to stay connected to another person but also allow himself to stay distant at the same time. Sam not objecting to how Cas got the information from the kid could be another example of how Sam has detach himself from his emotions. Whatever happen down there in the cage has clearly cause Sam to shut down from his emotions that in some ways seems questionable. As much as Sam would like to keep what happen buried inside he's going to have to acknowledge and face up to it eventually.

Here's a few questions I have:

What happen to him and Adam in the cage?

Is the reason for Sam shutting off his emotions have anything to do with what happen to Adam? 

Where is Adam is he still in there with Michael and Lucifer?

I know I for one can't wait to see and hear what happen in Lucifer's cage and to see why it is Sam would rather shut down then to feel anything.
