Remus / Sirius
They probably shouldn't. Remus looked hesitant which usually meant something was a bad idea. Sirius wasn't feeling great about it either, but it wasn't as if things like this -- mysteries -- didn't usually lead to some kind of answer. Maybe not good ones, but -- well. Sometimes knowing was better than not.
"Not on," he murmured, but flicked his wand at the door anyway, effectively pushing it open.
It was dark in there, and something felt heavy, and it wasn't wise for either of them to be without a hand to defend themselves, so Sirius only pushed himself closer to Remus, until their shoulders were touching, and they stepped in together.
