By nightfall, however, Remus has taken an Unbreakable Vow and agreed to move in. He leaves for the night, though, to return home and pack up for the move. He was more than touched to see not only his very own bedroom on the second floor, but also the secured cell-like room constructed in the basement for him to make use of during the full moons. There was initially quite a bit of hesitation in accepting the offer of moving in, but the cell calmed him a lot. Harry can’t blame him for being concerned; he remembers what Remus was like that night by the Shrieking Shack, in the Forbidden Forest. He can’t imagine being in Remus’ place and being forced to go through that every single month. Knowing he has a secure space to spend that time, where he won’t be able to hurt anyone, it must be an immense relief.
