Queen's Expressions

I'm afraid that's not quite true...in "Caged Heat" (which I recently rewatched in light of the Cas/Crowley reveal) at the end when Cas admits that things aren't going well in his war with Raphael, Dean DOES express concern, asking gently if there was anything they could do to help, and Cas replies that there isn't anything they could do. In other words, at least this one time Dean DOES express concern and offer aid, Cas had an opening (especially with Crowley on the forefront of his mind after his deception), and HE BRUSHED DEAN OFF. :/ He was probably too ashamed about Crowley, or too proud/self-assured his plan would work. I mean, if he wanted to he could have just asked them to help catch monsters all along, instead of going through Crowley using Sam's soul as leverage. So it's not all Dean and Sam here...
