As Superman had lasered the robot from above, Ambush Bug teleported to the Batplane's wing, electronics still in tow. Even from within the robot, he could figure it was time to leave. Of course, next to Batman, he began tapping on the glass. This, of course, was also Bruce Wayne. Not exactly the hardest secret identity to figure out, given the intersection of free time, disposable income, and desire for societal improvement needed to be Batman. Either way, the perfect person to ask about Arkham and drop off the parts.

"Uh, Mr. Way- er, Batman, I got some important-looking circuitry and... I think servos from inside the robot. I couldn't find any parts that were structurally significant though, which was odd. Also, I was hoping I could ask you some things about Arkham, pending an oncoming investigation. Such as whether the Arkham family was related to the family of the same name from Massachusetts, or if there are supernatural forces at work impairing the trea- you know what, screw it, I'll just come out and ask: is Arkham haunted?"
