Keeping a half an eye on the... flock of girls... she starts a circuit of the lake, venturing away from shore into the surrounding forest periodically, scoping out her - new home, pessimistically; starting point from which she'll venture to rescue, optimistically. She wants hiding places in which to stash things she may acquire; sources of food, like nuts or berries, because she has no idea what she'll be fed or how regularly; and any interestingly shaped rocks that could allow the creation of tools. Or weapons. Maybe she can alternatively break the curse by stabbing the bastard.
Then there probably wouldn't be a flock of braindead girls who look so much like her at the lake, now, would there.
On the other hand she can easily believe that none of them were particularly clever about less straightforward means of escape. Maybe she can cut his cloak and he won't be able to fly and then - well, she'll have to think this through now, even without that he'll be easily able to overpower her. She'll think.
She wishes she had paper.
She finishes her circuit of the lake and goes back through the orchard to investigate the castle itself.
She tries a side door.
Etty slips in with as little creaking as she can manage, judges the wind gentle enough not to slam the door shut if she declines to re-close it, and proceeds into the castle cautiously.
It leads her, with a few acoustic detours, to a room at the top of a tower. It's a beautiful room, containing beautiful furniture and a beautiful canopied bed, and in the bed is a girl who may or may not be beautiful under normal circumstances but is currently red-eyed and tear-streaked and cocooned in a tangle of beautiful sheets.
"Oh," she says, her voice wavering. "You must be the new one."
"Did he bring you just now?"
"They can't have all been so - despairing as to not even look for tools to get away in the obvious places. Can they? Whatever they are now." A shudder of fear goes through her. "Will that happen to me?"
"It takes years," says the stranger. "Years and years. I don't know how many. And then when you're too far gone he'll find another one."
"So do I," she snorts. "It doesn't mean anything. You're for the Baron. I don't know what he does with you; I've never looked."
