At that response, Remus scrunched up his nose a little. "Ah. I was worried you might say that," he told him. Nothing about this had been exactly normal so far - he was used to things not being exactly normal, but he got the feeling this was probably beyond was he was used to. The man was clearly a wizard, after all. Their definition of complicated had to be similar, at least.
He worried at his lower lip for a moment as he thought about it. There was a part of him that worried he was too naive and clearly about to walk into a massive trap, but then he didn't really have much option... and maybe he should learn to trust his own instincts more often. "Alright... yeah, okay, tea sounds good," he decided.
The dragon stopped him worrying, ironically. "He'd love it," Remus agreed. He was right - Ruby definitely didn't seem like other dragons, in the nicest way possible. He made him smile already.
