Big Bang Help!

[dosciencetoit]

I've been considering what kind of relationship Dean and Cas should have in my BigBang fic. I'd decided to make Cas ignorant of the normal workings of the human mind, with a liberal dash of BAMF, but I'm undecided on how the two of them would interact in a more intimate/personal setting. I feel like something normal/schmoopy would go over better, but at the same time, I find myself leaning towards seriously dysfunctional and unconventional.

Any thoughts?
