»I’m not a hammer, as you say. I have questions, I have doubts.«
See, Dean and Castiel haven’t known each other for that long at this point, but already, Castiel isn’t so sure of all the things he’s always believed anymore. And what happens now? He tells Dean a secret. This is Castiel’s deepest insecurity, and he chooses to tell Dean, to confide in him. This is the beginning of this really close and epic friendship, or love, whatever you want to call it.
