Remus chuckled. "You seem to also be assuming the only surviving wizards would be in Britain," he teased, nudging Draco's shoulder with his own to lighten the mood a little more. "Who knows how many pockets of American wizards there might be that we can't think of because we don't know their culture?"
His heart going out to his newest friend for the obvious emotional distress he was experiencing from the topic of conversation, Remus put his arm around Draco's shoulders in comfort without really thinking about it. "We'll do what we can in the time the bus allows us to see if we can't stop it from going on." He sighed softly. "I'm sorry for the things you went through during the war, for the way it seems like being here is bringing up all that darkness for you again, and for what you're going through now with Theo. You're a good man, Draco Malfoy and you're not alone. Not while I'm here."
Letting go of Draco's shoulders, he shook his head. "I'll have take your word for that. I've had a few short-term tutoring gigs where I can get them. But, I don't know if that makes me much of a teacher. Although, I would hope there was some charms, runes, arithmancy, transfiguration, and everything else thrown into the mix when my future self taught Defense. I wholeheartedly believe that to be a holistic discipline where your greatest weapon is knowledge." He smiled back at Draco. "Knowledge you get to be the beneficiary of now. Shall we try your spell again and see if the sigil works as expected?"
