largesse
Jason didn't want to admit it, but it was all thanks to Bruce's largesse that he was able to buy the snots some ice cream.
The old man literally threw a leather wallet at his face, just as Alfred was driving him out to work that morning.
For some reason, he found himself riding his bike at the crack of dawn, down the road back to the manor, where for some reason, —he really didn't care to ask about— the brood have come back home.
His homing instincts have gone awry, probably.
Dick was ecstatic. Cass was indifferent, but seemed to enjoy the company. The brat looked like a rabid dog, but he always did. While Tim was half-asleep anyway, his opinion on Jason's arrival didn't matter.
Alfred was grateful, for the full house. The amicable air he brought with him swept the lingering confusion and hostility under the rug, and Jason, at that moment, removed his helmet and slouched in relief.
The next morning was the same: loud voices shouting over each other, with warm food and hot beverages served at the table; mornings at the manor was one of Jason's favourite moments.
With Bruce at work, and consequently Alfred was out too, it was Dick in charge, and he took it upon himself to egg Jason to buy them all ice cream for lunch.
Surely, Jason would be okay with spending a couple bills on the twats and Cass, but before driving back to Gotham, he spent the last of his money on some meals he gave out to homeless kids he found living under a bridge. He bought them a couple blankets, gloves and scarves too, to keep warm in the last, and probably the longest of winter nights.
So he swallowed his pride, and asked the old man for some. Of course, he left out mentioning what he'd buy with it, but not forgetting to slip a "the brats wanted me to buy 'em some" in his dialogue, and he was sure as heck he saw Bruce's ears perk at that, and Alfred comically raise his eyebrows in wonder from the driver's seat.

That, and seeing the idiots and Cass happy made him happy.
