Dean got kidnapped by angels while he was getting groceries, one of which was an angel named Hutriel. It's set in season 9, when Sam is still possessed by Ezekiel. As in dean doesn't know it's Gadreel yet. The angels holding him hostage have him on a camera feed being sent to a laptop, and at one point Dean yells at Zeke to keep Sam away from where he is. After tracking down where Dean is, Sam tries to leave, only his body betrays him, with no idea why. No matter how hard Sam tries, he can't make it out of the bunker. This leaves Kevin and I think Charlie to go find dean themselves. Meanwhile Desn is either being questioned or tortured, I can't remember which. Dean is eventually rescued, then Sam asks why Dean yelled out the name Zeke, and who was he. Dean tries to brush it off, claiming he was yelling geek, in reference to Kevin. Dean requests to talk to Ezekiel, they converse briefly, and I think that's where it ends.
