Ok, after having time to think on this, I suppose my take on neither saw it as a romantic relationship is time senstive. I apologize if someone else has said this b/c I haven't read everything.

It isn't a romantic relationship right now. Doesn't mean neither want it to be, wish it could be, think of it being late at night when they're alone and don't want to be, etc.

Hence the eye sex, violations of personal space and power walking as though they were doing the tango. Hence Boyd Langton being made of fail with regard to power walking. Hence many more things too numerous to mention but you all know what they are.

Someone (dollsome????) compared them to Dean/Castiel and I can see that.

My 2 cents.
