Simon is, of course, oblivious to the fact that talking about a stranger fathering an illegitimate kid is about to get him punched. He just keeps staring at the man blankly. "Because she..." he starts to say, but whatever the mother of the child has done or not done or whatever is not finished, because Gus grabs him instead. He is pulled off-balance by it and stumbles back into Gus. It's Gus's turn to once again be stared at in that vacant way.
"He stayed behind. He stayed. He is there forever. Forever and ever and ever, ever, ever... But his shadow is on you. It covers. You are covered... And the dog... Don't let it come near...! No... No... I don't want it...!" he starts to babble up until the point he's pushed through the door out of the moonlight. He lets out another gurgling little moan, pressing his palms to his eyes. The stairwell is dark, lit up by a red light - the exact location presently unseen. Simon slumps a little, gripping the bannister and pressing his face to the wall.
Retourne, retourne, retourne, retourne, he thinks to himself, grappling with his mind. There are no ghosts or multi-headed dogs or discarded children here. That's not real. It's just a vision. It's not real. He's safe. But for the moment, he's not able to do anything but try to cling to his sense of sanity. "Daisuke," he mutters. "I need Daisuke..." Where is his phone? In his jacket pocket at coat check. Damnit.
"He gonna be okay?" a young guy with bright green eyes asks Gus as he passes by with a muscular, slightly overly tanned friend.
