Warning!!!!  If you haven't seen the latest episode of "Supernatural" and the preview for next week, do not read this!  There is going to be plot-based speculation and discussion! You've been officially warned!
This was a pretty standalone episode, so I really don't have too much to speculate about.  I do, however, just want to spend a minute talking about the Sam and Dean interactions this week.  First up, the opening conversation.
Sam, Sometimes You Should Really Just Listen To Your Brother
I realize that Dean isn't always right, of course.  But man, he was so right about this one.  And honestly, I'm really glad that he told Sam so because they did try it Sam's way, and look what happened.  Sam was unconscious for two or three minutes topside, and it felt like a week in hell to him.  That's pretty serious.  And Dean is obviously worried about his brother and trying to protect him, but at least this time instead of just sort of ordering him to not scratch the wall, he told Sam some of the reasons he felt that way.  Not a lot of reasons, but Dean is not exactly good at talking about his feelings.  Understatement.  And of course Sam is going to scratch the wall again at some point, but for now, I really hope he listens and just doesn't.  If not for his own sake then at least for Dean's.
"I've Got Your Back"
I really liked the end conversation Sam and Dean had.  Dean, once again, was feeling the weight of his life on his shoulders, and this time Sam was actually there for him.  It's been a while since that happened.  And the fact that Sam thanked him for getting his soul back was huge.  Dean went through a lot of crap with Robo!Sam, but to know that his real brother was glad he got his soul back was something Dean desperately needed to hear.  And he also really needed to know that Sam had his back, for real this time.  Compare this to the last conversation they had where Dean asked if Sam had his back, and the difference is huge.  They really are back in this together.
Lisa and Ben
What do you think, everyone?  Is it really over between Lisa and Dean?  I can absolutely see Ben doing this and getting Dean back to Lisa's house because Ben really loves Dean and idolizes him and misses him a lot.  But the conversations Dean had with both Lisa and Ben felt pretty final to me.  I think at this point, Dean would be more willing to stay for Ben than Lisa, which isn't fair to anyone.  I did like that Ben called Dean on the family thing, though.  I don't exactly agree with Ben that he and Lisa are Dean's family, but he was right about the whole "people who love you even when you're a dick" part.  That might not make them family, but it does mean they've earned the right to a proper goodbye and not just avoidance on Dean's part.
And that's all I've got.  Thoughts, comments, concerns?  Who's super excited about next week's episode?  I sure am!
