"Yes."

"Wishes, huh?"

"Yes. It actually took a bigger one to fix you than the house. Living creatures are complicated, and the house didn't have any inherently magical installations."

"It's a little more complicated than that. I wouldn't have left you unsupervised near anything both destructible and irreplaceable in the first place. Had I done so for some reason, I would probably mourn the loss of whatever was destroyed. But in reality I have plenty of magic and I was warned to expect destruction of property, so there's nothing to be mad about."

Elspeth goes out and inspects the smallish amount of damage to the plants around the house. She fixes it as she finds it.

He's back a few minutes later, with his poof and its fountain.

"Aww. You took them out first."

"Poofs," she adds, "emit an anti-injury field. It works on them and anyone nearby."

Elspeth fixes a tree.

Felicity carries his poof inside.

Eventually there is no remaining fire damage or ash that Elspeth can see. She goes back inside and picks up her tablet from her pillow where her wish restored its existence.

Felicity and his poof remain in his bedroom.
