"Wh-- no!" Remus said immediately. "No, I don't know," he added quickly and he didn't look like he could expand on his gesture or his response either. It had been October of 1981, the last few days of it, prior to his arrival in this past version of New York City and wish as he might that Selina was just pulling his leg, it was a fool's hope. Europe and Northern America were both in the same hemisphere so the moon couldn't just suddenly switch sides just because he traveled three-thousand miles over. On top of that was Selina's reaction on Cuba's threat. That's not a very easy response to fake in a snap of a finger.
In his mind, he was already making calculations, his right hand itching to count the digits for him except it had his wand but in the middle of it all, he would stop, stumped. He was at July 13, 1964 with a moon that was just about to turn full. When would it turn full and when was the last full moon? He had to know but he couldn't, he knew nothing beyond the date that night!
"No, I do not know whether Cuba will attack or not," Remus repeated after a solid pause, himself trying to rein in his nerves, again. His thoughts were still on the upcoming full moon, second on the sudden shift of time. Merlin's beard, how the hell did this happen?
At least he certainly won't be missed in real time...
"You..." Remus shut his eyes tight and pressed his lips together. Scatterbrained, the shock of having been transported through time was finally getting to him and his priorities had become muddled because of it. Opening his eyes, he said -- almost begged to Selina, "You can't be serious...today can't be...it isn't...!"
