Yep… the clue was the band-aid, among others… like, well… who comfortably knows Bruce… AND knows his identity?
Who would be writing, what seems to be, Bruce’s life story from his first case onward?
Kinda narrows down the field.
The field is further narrowed down when we realize who, in the DC Universe, is a reporter and a writer, knows Batman’s identity… and is a man. (Well, alien… man.)
To Clark Kent, this… Batman’s life story, would cap a brilliant career, if he could one day publish it, and Bruce would allow it.
Which bring us to the band-aid. In my mind, Clark Kent goes to work periodically with a band-aid on his face, neck or hand… (“Cut myself shaving this morning.” “Oh, it’s just a little paper cut.”)
