He goes to put away the remaining food items.  Finds Hawk and scoops him up and gives him a kiss on his gray little kitty forehead and brings him downstairs to show Promise.  He knocks, and projects from the other side of the door, "Do you want to meet the cat?"

"To meet it? Does it talk?"

"No, but he's, y'know, a creature and stuff."

"I guess I can encounter the cat."

He opens the door!  And closes it behind him!  "So, this is a cat."  Said cat has his paws lined up over Zeal's shoulder such that Zeal has to turn most of his back to Promise in order for her to see him.  He's stripey and has big green eyes.  "His name is Hawk."

"Is it a problem if I turn out not to like the cat?"

"...No-o.  It might be convenient if you did but I don't think - it's not a problem.  It wouldn't be."

"Because it seems... uncanny... and I do not know if I will get used to it."

"I definitely don't personally care whether you like cats.  It would be logistically convenient if you did, because he normally hangs out in my room, sometimes, and if he's in here with me then that covers some small amounts of noise you might make.  To my parents."

"If you were to put it down would it touch me?"

"Probably not; he's not very lovey with strangers."

"Then I guess it's worth seeing if I get used to it."

Zeal pulls out the chair that goes with his desk and sits in it.  Hawk backs down off his shoulder and into his lap.

Zeal pets him contemplatively.  "...Do you have night terrors or anything?"

"I am generally asleep when I'm asleep so I don't really know if I have them conspicuously."

"Ehhhhgh.  ...Do you normally sleep about a third of the time?"

"Yes."

"Okay, maybe we can get you on a schedule where you're asleep while my parents are at work, so even if you're noisy they'll never hear you."

"That makes sense. Where do they go?"

"They manage a motel, or - an inn?  If you know what inns are?"

"I think I'm getting a loose sense from the word but fairies don't have those that I know of."

"It gives people travelling a place to stay overnight."

Nod.

"So that covers five days out of seven, once we get on that schedule.  The rest of the time... I can try to be around, to - intervene, in whatever way you'd prefer, before they could hear you."

"...what happens on the other two days out of seven?"

"They don't have to go to work.  Sometimes they go other places, like right now they're out getting food, and tomorrow morning all three of us will go to church for a few hours, but in general the schedule is much less of a sure thing."
