"Yeah, he's great. Far more creative with charms and spellwork than I've ever been," Charlie enthused. Charlie was far more competent at spellwork than people sometimes seemed to think. They saw his bulk and the fact he used to work with dragons, and tattoos, and nightclub ownership and just seemed to think he was a little lacking magic or brains wise. People tended not to realise just how much spellwork went into keeping dragons in check. And a lot of the people he dealt with these days were too young to realise he'd been a good student of everything aside from Arithmancy. He'd just never been much for creating new things or combinations.
He smiled kindly at Theo and gestured to his left side. "You want to stay on this side, I don't want to accidentally stamp on your foot with this," he said, patting his right thigh lightly. "Um, you can either lean on my arm like so," he said, holding his elbow out so that Theo could grip onto it somewhat like a pair of regency ladies 'taking a walk'. "Or you could put your arm around my waist and I'll do the same. I'd say stick your arm around my neck but the height difference might make that more uncomfortable, unless you'd prefer it. Basically fucking anything that's going to let you lean some weight on me. I'm perfectly stable." That last was said in a reassuring manner.
Once Theo had sorted himself out as he wished Charlie tried to take as much of his weight as he'd allow as they moved slowly through the short corridor which blocked the noise between the floors and through the second set of doors before they moved on into the main room. He was doing his best to allow Theo to set a pace which worked for him.
