Riddler was expecting a fight. "Of course I'm not." The Nox keeping still, keeping talking--that's...unexpected.

The metal continues its screeching protest. Riddler continues standing where he is, fists clenched, nails cutting crescents into his palms.

"Is that a threat?" He's still off balance by everything and it's pathetic. He's not supposed to be stupid, he's not supposed to make even more mistakes, but that's just his life, isn't it.
