[Huh. Put it in a box, tie it up with string, appear string tied around watch, disappear the box and string on your say-so?]
[...Weird, but functional,] he says. [But if you're going to be disappearing the packaging afterward, you may as well include a plate and possibly a napkin.]
[That can be arranged. If taking over the world doesn't work out maybe I'll open a magic restaurant. ETA on the carrot cake coming out of the oven is... five minutes apparently, triangles do cooling, then it will take a minute for Alice to frost.]
A car pulls up outside the warehouse. Normally that would not be apparent to the person inside, but this car happens to contain a mint. With a familiar power signature.
[Cancel the carrot cake,] he says urgently. [No cake for me. I've got a visitor.]
And the rest of the magic around her is also half-familiar: Chris's power, seen from the target instead of the source.
[At least it means we don't necessarily have multiple sinister organizations regrettably fascinated by us,] Bella points out. [What's she doing? Brainphone me a running transcript of the entire conversation and commentary on anything else you notice.]
[Okay,] he says. [Can most people do that? I don't think most people can do that. I'm pretty sure most people can't do that, actually. I apologize in advance if half of it comes out in French.]
"Sorry," he says, "I just don't really know the polite way to talk to my kidnapper."
Bella doesn't want to distract him with unnecessary commentary, but she can't resist, [Zing!]
"This was not my favourite option," says Libby. "I prefer not to use magic when I can get by without it; I think you've figured out why. But when I realized who Chris had put you in touch with, well, I had to do something."
"I don't actually know that she's dangerous," she says, "but more to the point, I don't know that she's not. And it's important to know that, because if you spend enough time with her, you could end up teaching her very dangerous things. Not even necessarily on purpose. But let's just say: there are some kinds of magic that, carelessly or maliciously handled, could lead to the destruction of all life on Earth. I would rather keep them in as few hands as possible."
