Bill lulling Ford to sleep by petting his head/ruffling with his hair. Ford finds it really relaxing. Bill finds it "cute". Bill pulling a "what's that on your shirt" and then flicking up his nose as a joke while doing equations and it takes Ford a few moments to understand what just happened. Ford readjusts his glasses and laughs with and cute cringed up face of "what the heck you weirdo" type deal and Bill laughs too. Ford finally found someone who is as out of place as he is.

I LOVE IT
