Remus felt that was something they could both agree on. He didn't want Severus there any longer than he absolutely needed to be. But at the same time, he didn't want the Slytherin to rush through whatever it was he needed to do in order to help Sirius. He wanted it to be thorough, and done properly -- whatever it was. He still hadn't gotten any answers, and he still wasn't sure if he was okay with that, but he didn't really have much of a choice. Sirius couldn't carry on this way, and he didn't have any answers that wouldn't land Sirius in the psych ward at St. Mungo's. Remus wouldn't even entertain the thought that maybe that's where he ought to be right now. That wasn't an option.
"Right, then," he said, and nodded. Fortunately the common room was empty, which was a bit of luck. No one was around to ask any questions as to why Severus Snape would be heading up into the dorm room belonging to the four boys he normally wanted absolutely nothing to do with. Remus wasn't in the mood to answer questions anyway, so it was just as well. He gestured for Snape to follow him, and took him up the stairs of Gryffindor Tower to that led to the dorm rooms. He paused outside the door, and looked back at Snape. "He doesn't know it's you. He just knows he wants to do whatever it takes to fix what's wrong with him." He just wanted Snape to know that he probably wouldn't be receiving the most welcoming greeting, though he was smart enough to have deduced that under any circumstances or pretenses this wouldn't be the most pleasant of meetings.
That said, he pushed open the door and walked inside. "Sirius," he called out quietly. "We're.. here."
