Remus knew that he had to be strong right now; that, that was what Sirius needed, so he didn't flinch when Sirius snapped at him and instead simply let Sirius do what he needed to. He knew what Sirius had gone through when he'd gone back, because Remus had gone through it before he'd been brought to Colligo. He'd been convinced that Sirius was guilty and had been angry at him for betraying them, but he knew better now and knew that Sirius needed time. Time to heal and hopefully he would be his old self again; not that Remus would love him any less if he stayed the way he was now.
"Of course." Remus said, closing his eyes as Sirius' forehead pressed against his own, his fingers buried in Sirius' hair. Holding on tight, he visualized their apartment, which Remus had been living alone in for the last few months and within seconds they were no longer standing on the sidewalk outside the library, but instead in the living room of their apartment.
