Aaron gets everybody money but courteously does not tell Miranda that he already has Wealth of Nations and she should have gotten him money. 

He gets Aaron money! He gets Michael a piano that doesn't lose its tune when shrunken pocket-sized and then expanded, which Michael had complained about for years with inferior pianos. He gets Michael's help on designing Miranda and Karen standard-looking Hogwarts robes that self-regulate temperature and deflect minor hexes. 

And Timothy gets Miranda a cat. Well, a Kneazle, technically.

He met the cat in Italy, when it bit him; he was making Feverfew trail a politician for him. He recalled Feverfew and the kitten hissed and snarled and stopped when he took off the Imperius. Though it still glared at him disdainfully.

He had a feeling that it might get along with Miranda.

"Ooh how'd you make these - hex deflection'd be handy for Stoller -"

"That's the first-year you adopted?"

"Yeah but there's only so much I can do when it's a sixth-year hassling her. He's mostly backed off as long as she avoids him now."

"Black?"

"How'd you guess - should I have asked you for blackmail on him or something, am I very remiss in the care and feeding of my pet firstie not bugging you about it even now you're out of school -"

"I very much doubt remotely managing the wellbeing of Muggleborns in Slytherin is a valuable thing for me to be endeavoring to do. I wouldn't've blackmailed him, actually - would probably just have told him he was eroding discipline in the common room -"

"Molloy tried, didn't help much."

"No one got to the kid in time to warn her to implausibly claim decent ancestry?"

"She ran into Selwyn in Diagon Alley."

"I should talk to the board about a better procedure for contacting Muggleborns in the first place - arrange an orientation and a shower for them before they -"

"Do Muggles actually smell or do people just say that to be mean -"

"No, it's true, it's just not morally relevant and also if the Statute were gone we could fix it."

"And reading lessons."

"I learned to read when I was three, I don't see how Muggles don't -"

"They don't have any books, their parents don't have time to teach them and they can't all afford school..."

"No one taught me."

"Muggles as smart as you probably come out fine."

"Yeah. But I think being smart and being randomly magic are mostly uncorrelated." Her new kitten yawns awake. "- is that a live cat, I was assuming it was an enchanted statue you'd explain at some point -" The kitten bites Timothy. "Is that a live cat that hates you."

"It is! Merry Christmas."

She picks up the kitten. "What nefarious plot is served by my ownership of a cat that hates you?"

"He resents my conduct towards Feverfew. And noticed it immediately."

"Your conduct towards Feverfew?"
