Yeah, she doesn't have anything to say to him right now. She could maybe come up with something - "Why did you eat all those maidens", "Well, this room is a mess now", "Don't even think about trying to consummate our marriage", "So, these are called thumbs, they're useful", but. No. Just no.
And then she heads for the door.
The other prince is sitting on the floor of the hall, looking nervous and upset.
He brightens when he sees her.
"You're alive! Oh good."
"Yes. I mean, I might be crying too if my mother had screwed up magicking me into existence and then someone had to put me through an elaborate and painful series of steps to fix me."
"Be my guest." She slumps against the wall. "Meanwhile can I get water, somewhere?"
He fetches a maid and leaves her in the hall with the instruction, "Please get the princess anything she asks for," and then goes into the room.
Oh right. She's a princess.
...cool.
She gets some water, and some bread and butter for breakfast, and then she wants an actual bath and a fresh dress with no blood or milk on it, and then she comes back to see what's up.
"Hello, Princess," he says when she comes back. "...Um. What's your name?"
"It's, um, it's good to meet you, I guess," says Taphinieu. "Welcome to the family. ...um, speaking of which, there's some things I think I should tell you if you're going to be around and married to my brother and all."
Eventually he settles on: "...it's not good to upset the king."
"He did routinely kidnap people expecting them to get killed. Do you mean apart from that?"
"What else is wrong with him, and have you tried going outside and being conspicuously dismayed?"
"Yes," he says. "When I was a child. And the mysterious old woman said, 'If you try to be kind and responsible even when it's difficult, and remember that just because you're being punished doesn't mean you've done something wrong, things will sort themselves out eventually.' I don't think she usually gives advice like that."
"Yeah, that's weird. You didn't have to eat any non-food or combine inanimate objects in unconventional ways. Are you sure she was a real mysterious old woman and not just a well-intentioned elderly lady?"
"I thought sometimes she might've been just the ordinary kind of old woman. But she looked very mysterious when I met her. And I think it turned out to be very good advice even if it wasn't magic."
"I mean, that's good, then, but it doesn't necessarily guarantee that things will sort themselves out."
