Purple continues to stand there, quiet and afraid.

"Oh, I'll figure out what to do with you later," sighs Yellow. "Are you hungry?"

"No."

It doesn't count as an interruption if he stops himself from rambling about his day and whether he'd be hungry or not and why not, does it? He doesn't know what definitions this guy is using.

"Don't eat if I'm not around," Yellow adds. "But if you're thirsty you may take water from the pitcher there - not the lake water, don't drink that."

"Ok."

Is it obvious that he's still frightened? (Yes. Yes it is. Because he is very frightened.)

"If there's anything you need for this to go more smoothly," Yellow adds with a slightly barbed smile, "let me know. I let Promise draw, that sort of thing."

"… Do you have a bathroom? Uh, I don't need it, I just mean it would be useful for the future."

"You can bathe in the lake as long as you don't drink the water," says Yellow, waving a hand.

"… I mean to use the toilet?"

Apparently that's not something winged people do, but Yellow says if he needs to he may go out to such and such a place in the woods and dig a hole - "I'll have Promise shape you a shovel" - and be unpleasantly mortal there.

… Are you kidding him?

He stands there, looking somewhat incredulous. And frightened. That too.

"Stop looking at me like that," says Yellow.

So he does. He stops looking both incredulous and frightened. Instead he just looks sort of numb, and he feels rather terrible about it, not that you can tell from looking at him, because he's busy looking sort of numb.

"Would you be any help building an addition to this house?"

"As a manual laborer, probably?"

"I suppose that will have to do. In the meantime you can sleep on the floor in that corner. However much sleep mortals need."

The door opens.

"Promise! I caught a mortal. He's going by Purple. Purple, cooperate with Promise while I'm gone," says Yellow.

Yellow is not yet gone. Purple therefore does not ask Promise about what they might be cooperating on.

(Scared. But looking numb.)

And then Yellow pats Promise on the head and goes out.

"...Hello," says Promise. "How'd he get you?"

"I don't know how 'getting' works."

"Did you eat something, or did he get your name?"

"Name."

"How'd you get here?"

"– Lake?" he tries again.
