Rich didn't have any siblings and had never really been able to picture a world in which he did, if he was being honest. But Dick did seem pretty cool, and he didn't act like any kind of parent, even though it was still pretty obvious that he did, maybe, care. So maybe this was what it was like. He decided that he wasn't going to think on it too hard. It could just be what it was for now. No biggie.
Anyway, he was mostly focused on the doors. On the endless horror voids beyond them. Yeah. He was suddenly pretty fucking glad that he wasn't trying this out alone - it was likely he would have tried that one and then turned straight around and left this entire building before giving it another go.
"Well, that was a whole lot of nothing," he said after a beat, and then deliberated the other doors in front of him. Lots of options. Lots of room for terror. Still, he moved two doors down and twisted the handle open. For his troubles, he was greeted with bright lights and the familiar noises of arcade games. That could be scary too, considering the last time he'd been in an arcade he'd been bullied out of it, but he wanted to give it the benefit of the doubt.
"...Psycho clowns?" He asked, turning 'round to look up at Dick suspiciously. "You're not from Derry."
