The Riddler presses his lips into a very thin line and inclines his head, eyebrows raised. It's a Look. He's giving her a Look. His tone of voice is nothing if not amused, however. "I suppose I should at least abide by precedent."

He slowly shakes his head. "Unfortunately, no. One last guess."

The construction worker has ceased whatever it was he was doing that bothered Riddler so, so he has the relief of no longer having a gun against his skull. It's relief tinged with the knowledge the Riddler still might shoot him, but that applies to everyone, really. Especially the little red-haired riddle solver.
