Bruce and Clark have this weird tension between them, and Bruce thinks that Clark hates him for everything that went down between them in Batman v. Superman. Bruce is resigned about it, thinking that one of these days Clark is going to make good and vaporize him.

Maybe Bruce is just walking through the halls of the newly minted Watchtower, or working in the Batcave, but either way Clark is suddenly there. He pins Bruce to something without breaking a sweat and Bruce thinks he's dead for sure, but instead Clark leans in and proceeds to whisper the absolute filthiest things into Bruce's ear. It all leaves Bruce as nothing but puddy in Clark's hands. Turns out that Bruce was very wrong about just what Clark wanted to do to him.
