His voice was thick with sleep, sounding strangely Batman like.

Hee, I somehow love that little touch, that he sounds like Batman when he's half-asleep. It makes sense! And the image of the two of them heading out in their jackets (dark blue cashmere, yummy!), and all the little details of the day...I really liked the way the conversation flowed, how comfortable they were with each other. So nice!
