Albus had waited to go and speak with Remus again. He wanted to find the right moment, and he also needed a day or two for him to calm down, however when he discovered that Sirius and James were present, he decided that this was the right moment.
He used one of the shortcut and finally reached the second floor. There were a few stops, and more people to talk to, but this was a good thing. He had forgot how important this was. Just a few months, and he'd lost his connection to the castle and he would not do it again.
Finally in front of the right door, he knocked, and waited, smile on his face, waiting for one of them to open.
