Who: Remus, James, and Sirius AND OUR NON-EXISTENT PETER sob
Open? To anyone with reason to walk in! (So that means mostly Percy)
When: After those slew of other posts. Enough time for people to settle down. Somewhat.
Where: 6th Year Gryffindor boy's dorm
What: Remus has a confession to make to his fellow Marauders.
Even though he had wanted to tell James and Sirius as soon as they got back from winter hols, it was one thing after the other. And then when he had tried to tell them on Friday, there was another Big Thing and that was just bad timing.
But no more. He just had to suck it up and stop looking for excuses to delay the inevitable. He had to tell them sooner rather than later.
So he called yet a meeting, telling James and Sirius to both be there or else he'd be forced to find some way to magically drag them to the room. It didn't matter if they weren't talking to each other at the moment because they didn't have to talk to each other. He had to talk to them. Remus was sitting on his bed, nervously fiddling with one of his broken quills as he waited for the other two to arrive.
