It had started with a riddle.

Your first day at the GCPD had been rough, Gotham was rough, until you'd been surprised by the forensic tech at the scene. And he'd asked you a riddle. You weren't very good at riddles, but you did your best to answer regardless. And although you got it wrong, he got excited.

No one even let him finish his riddles, so you'd delighted him just by making an attempt.

And that's how you met Edward Nygma.
