Tristan is one of the few adults in this school who would probably humor that request to be called by a different name, without questioning it too much. Of course, that only applies if he knows it's wanted. Upon hearing that, he takes a moment to place the face and match it to what he's heard from teachers and what's in his files.

"Riki, right? Your teacher told me you would come by." And a few things about why, but he'll see what the kid volunteers. "Come in." He gestures over to where there's a couch, a comfy chair, a small table with a couple more standard issue school chairs around it. There are, of course, places with more or less cats. "You can sit anywhere you like."

He gets up to move over and make sure the door is closed behind him once he does come into the room fully. No one needs the threat of prying eyes and ears from the hallway.
