One of Remus' strongest suits was the fact that his brain never really stopped working. Even though he was currently in quite the shocked state, on the brink of completely losing it, his mind was still racing. It was grasping at any sort of logical explanation, however small or minute it might be, to try to sort out what was going on. That was Sirius, unless Remus was hallucinating or under some sort of spell. But he didn't look the way he did when he last saw him. It wasn't as if he'd looked haggard or anything when they last were together, but there were signs of change; the effects of the war, the stress, the pain and suffering they'd all endured had caused them all to look rough around the edges. No, this was the Sirius that Remus knew at the end of their schooling years, perhaps just a bit after. Handsome as ever, young and without much care for anything except a laugh and his mates.
So how was that possible? That was where the disconnect was between his brain and the logic he desperately craved. Whatever it was, it was painfully clear to him that this Sirius had no clue why Remus might be a bit... concerned about seeing him. Did that mean, he didn't know? "You were going to meet us?" He repeated the words as a question. "Where?" They'd not all been together in quite some time, not since before James and Lily went into hiding. Then it was just him and Sirius, occasionally Pete would pop in but the lot of them had been separated for a good while. "I mean, where were you going to meet us?" Was he asking the wrong questions? What were the right questions? His brain was still trying to sort it out but it was not nearly as fast as he would've liked.
