I loved that this episode reminded Dean of his humanity, and his need to protect his brother is one of the things that keeps him human.

I also think seeing his Sammy taken over by Lucifer absolutely killed him—the tears in Dean’s eyes made me extremely emotional.

Could Castiel be any funnier?! That man has the greatest dead pan line deliver I've ever heard :)

And I'm glad that the brothers are together again a well—they need each other to get through this.
