[He has two choices here, he figures. He can charge at 60, using his unknown position to surprise him and potentially gain the advantage- only, his limbs aren't cooperating the way he'd like them to, and in the split second it takes for Connor to raise his own heavy arms, 60 could probably just shoot him. Or he can continue to hide... which isn't likely to work for long on 60. They both have a tendency to explore every nook and cranny, after all.

Maybe there's a third option? He could try talking to him. It's not likely to get him far, but he does need to see if 60 is being affected the same way Connor is. He can formulate a better plan once he has more information.

He shifts very quietly to hide behind the door, instead. When 60 opens it, Connor will be already pointing his pistol at him.]

I wouldn't try anything, if I were you.
