Scamander brightened when he saw the smile on John's face. He felt like a bit of a twit, really, because of how much he liked being the one that put it there. He moved to find a spot to put the cage down so that they could get a better look at the bird. He could come out, of course, but not until the mice were safety relocated. The owl couldn't get at them in their cage, but it was probably best if he didn't terrify them trying.
"What do you think of him, John?" Scamander said proudly, putting an arm around the other man's back and gesturing happily to the cage. "I saw him and thought that you would like him, yes? And that it was we could name him together." Of course, owls were useful creatures for anyone to have. It certainly saved a trip to the post office, but that wasn't why Rolf had collected one. He'd picked up on Dawlish's fondness for his childhood pet and he wanted to capture a little bit of that. He knew that when he'd moved in with John the man had been sad and he'd done his part to help make that better, he felt, and it was something he wanted to continue to do, both by being there himself and by doing things for him.
The breakfast that John was warming reminded him of how hungry he was and he bent to kiss the side of Dawlish's hair to thank him for the effort. He too felt the dread of the impending Monday, but he wasn't plagued with worry concerning his own job. He was worried about the DMLE and what might happen to John if things suddenly went bad.
He knew that he shouldn't tell him about the Order of the Phoenix, and he wasn't going to -- not yet at least. There wasn't any reason to tell him what he was involved in and the network that he'd be setting up to help with werewolves. He didn't like keeping secrets from him, and he obviously trusted that were he to tell Dawlish anything, John would keep the secrets for him, but he didn't want to put him in that position. It made him feel a bit guilty though, and in its own way, purchasing the owl was an attempt to fix that feeling.
