It was nice to see a smile back and Theo returned it, albeit a little self-consciously. He was curious about Charlie's leg but not so much so that he'd hurt or upset Charlie asking about it when it wasn't his place. He gave Charlie room to move and was pleased to see him move around okay, even if it wasn't as smoothly as it could have been. He was surprised to hear that he was speaking to the club's owner, but then it did make sense that he'd want to go somewhere he felt comfortable, even if it was a little further away.
"I'd be happy to help you get to the Club, if it'd be more comfortable for you." Theo suggested, flinching again, if a little harder, when Charlie's wand sparked. "We could Apparate?" he offered.
