Though the suspicion gradually faded away, the confusion remained, especially when he started going on about spirits and demons and her being in a completely different world. If not for the fact that she'd seen her fair share of weirdness over the past few years, she would have wondered if he was touched in the head.

"You're saying I somehow sleepwalked through a portal into a different world, and a bit of the portal's magic has embedded itself in my hand?" She could have sounded more incredulous, but as much as she'd learned about magic over the years, she knew that there were all sorts of anomalies that magical theorists had never been able to account for.

At any rate, this man had saved her from a flock of ornery birds and he was offering her help, so she could take this one step at a time. "Thank you," she told him before reluctantly drinking down the potion. She'd had Xenophilius Lovegood's horrid tea, so she wouldn't exactly complain about anything that wouldn't outright kill her or cause her harm. "My name is Hermione Granger. I don't suppose there's a quick and easy way to just send me back to where I belong, is there?"

If there were, he likely wouldn't be offering to help patch her up and get her warm.
