It’s a bell. You wonder for a moment if they took the bell hooked up to the emergency exit; you can’t see it clearly from here, as a rather big fellow is standing in front of it.
Well, even if they have, you don’t see how it’s important. But it does offer a way to start the conversation without going straight to Burgundy. Maybe for the moment you can present yourself as a restless patient.
“What’s that you’ve got there?” you ask, approaching them.
“Oh, it’s the bell for the emergency door,” says the knight holding it. “We had to let someone out earlier and the damn thing kept going off. Since this door’s not supposed to be used right now anyways, figured it’d be best to just take it apart and reassemble it when things settle down.”
“I see. Did you tell the staff about it?”
“Didn’t have much choice,” says another knight. She was one of the ones talking earlier. “Burgundy was around. He insisted that somebody tell the doctor and nurses immediately once we did.”
“Hey, you don’t have to sound so annoyed,” says the other of the gossiping knights. “It got Brian out of our hair, didn’t it?”
“Don’t get me wrong, I’m glad not to have to deal with him any more than I need to. But it’s strange that he isn’t back yet. You don’t suppose he went after that man who looked like he was auditioning for the Marshguards?”
That must be Crow, or whatever his name is.
“Wouldn’t put it past him, honestly,” says the one with the bell. “He’s gotten in trouble more than once doing his own thing instead of following orders. Pretty clear he’d rather pick fights with Marshguards than do pest control.”
They barely even seem to be noticing you. It looks like they’re mainly interested in gossiping.
So maybe it’s best to see if you can nudge the conversation back towards Burgundy somehow. That might let you learn what you need without drawing too much attention to yourself.
