There is an organ somewhere inside of Bruce that tells him to recoil from these moments of emotional honesty. That could scare him, not laser eyes and super strength. (Of course he isn't afraid, all Clark was doing back there was fucking his brains out, it's not like they were trying to kill each other. Cakewalk.) A vestigial thing regrown in all his efforts to be a living nightmare, gliding along rooftops and swooping through alleys.

He watches Clark. Eats the last bit of his donut, and lets his hand sink into the cold water. Fingertips just over the surface, conflicted about getting sticky residue into the water.

"We both have habits. About pretending."

Probably the thing they're mutually most in danger of doing. Clark and his need to stay apparently human, on top of having a secret superhero identity. And Bruce 'it's not any of your business if I love you' Wayne. What a team.

"I felt it, with my eyes closed. It was just warm."
