When Marky whirls on him, Grayson straightens up, eyes widening slightly. His fight or flight response starts to go, his hand tightening around his kit. He's ready to defend himself if nothing else.

He is pleasantly surprised when Marky seems to rein himself back in, and surprisingly empathetic when he sees the other well up with tears. Suddenly, there's a lump in his throat.

"I dunno," His voice sounds strained, down to a whisper. "I haven't had a chance to look around much, but someone's put a sign on the door - well I guess it's an exit - anyway it says not to go out without a gun. So if the rest are here, then..."

A thought strikes him.

"Then we're all... dead." He recalls Marky saying that earlier, and now it's finally hitting him. "All of us?"

Before Marky can answer, he's taking a shaky inhale and walking past the other, further into the room, towards the corner. Back turned to the other, he shakes his head. Now he's crying, uncurling his arms to try to wipe his eyes and cover his mouth.

"I'm still waiting for the punchline, or to wake up. I'd-- I'd really like to wake up now."

Until he'd seen Marky, it wasn't real. And everything Marky kept saying made it more and more the truth. Grayson knew how to be rational when the chips were down, but right now he feels insane. All of it does.
