There's a lot of people who catch your attention here. Even if only for a brief second, you wonder if it's worth talking to them.
You quickly dismiss most of them as either not worth your time or someone you could talk to later.

One of the guards is pacing around the cafeteria. She's muttering something under her breath, clearly worried about SOMETHING. Part of you wants to check up on her but...
Something else catches your eye first. The redhead can wait.

There's a man sitting at one of the tables. On closer examination, he is wearing a cherry red labcoat. That's all you can make out about his appearance. The rest of his body is an indistinct humanoid smear that your brain is having a hard time filling in.

You look away. What were you talking about? Something about a man?
Wait-
You snap your gaze back to the table you were looking at. The man is still sitting there. You think he's eating something but you can't make out what's on his tray.

The other researchers, security guards and random oddjob workers sitting at the table don't even acknowledge him. None of them are talking or looking at him. How is no one noticing this guy? There's one spot open next to him - guess that's where you're sitting if you wanna talk to him.

Your first thought is: Is this thing an anomaly? Did it break out somehow? What is it going to do? You need to warn security about this.
You tighten the grip on your tray. You hastily march over to the nearest security guard that would know how to deal with this thing.

The first guard you find looks like he knows his shit. You can't make out his face but, unlike the man, it's not for any possibly anomalous reason. His face is a mangled, charred matrix of scar and burn tissue. Where was once a nose, there's only a caved in hole that he struggles to breath in and out of.

The only parts spared from whatever horrors he has seen is his mouth and his left eye. Flesh has grown over the empty socket where his right eye used to be. Not like the rest of his body is any better. Liver spots and wrinkles cover his body from head to toe.

His body is lightly armored with knee/shoulder pads and a Kevlar vest straight out of police surplus. A subnose revolver hangs on his holster - Okay!

Okay, yeah, this guy can help you! He's clearly dealt with far worse, right?

His one good eye narrows as you approach him. "What's the matter, boy?" A raspy, gravelly voice croaks through his ruined throat. "Lost? Ya sit at one of them there tables and ya eat. Ain't that hard to understand, boy."
Your eye twitches. He did not just call you a 'boy'. Okay, whatever, this is more important. "No, I have something to report."

Now this gets his attention. "Ah shit. Was hopin' I didn't have to do no work. What's the issue, boy?"
"Stop-" You hold your tongue. "I have reason to suspect that there's a threat in this cafeteria." You point to the table where you saw the man.
