You are a guard at Arkham Asylum and are assigned to watch over Edward Nygma (aka Riddler), normally out of boredom you answer his riddles as you stand in front of his cell. It his coping mechanism and his way of getting attention (he a attention whore), once in a while you play a game of chess or cards with him on your free hours.

Letting him win as he mocks you for not being smart (it kinda cute watching him have a big ego), it your way of letting him open up without having to use force. Normally you don't carry a weapon on you since patients will think you are one of those bad guards that give out "punishments" for no reason, but you do have a radio on your belt and a set of keys for the cells

Sometimes you start up the conversation by bringing up a random subject and let him either rant about it or correct you on it. You do know a few random information that helps you to have a real conversation with him.
