Gliding powerfully out of the night, Batman alights on a rooftop and whips out his high-powered night vision binoculars with GPS targeting and a tiny unfoldable bayonet. Arriving a few minutes later, Supergirl walks up and asks him what he's doing.
"Scanning for Superman, of course."
"In that woman's bedroom?" She gestures at the subject of Batman's gaze, 6 stories up in the high-rise across the street.
"He could be anywhere," the Bat tersely responds.
Supergirl flies away, shaking her head and muttering, "what a weirdo."
