Regulus was here solely for the food. Interaction with others was incidental.

There were many things that he was good at that might surprise others, such as how knowledgeable he was at taking care of his clothing. He knew all the right spells to keep his clothes looking clean, neat, pressed, and well maintained. He could fix just about tear or damage, he could remove just about any kind of stain.

He knew nothing about how to prepare food.

House elves cooked and clean the house, but could never touch human clothes.

Regulus piled his plate with food – all kinds, appetizers, mains, sides, desserts – he didn’t care what was touching. And when the plate was full, he took out his wand, performed a preservation spell and then magically vanished the plate. He was actually sending it back to his room.

And then he grabbed another plate.

He figured he could get at least a week or two’s worth of meals this way, maybe enough time for him to figure something else out for food.

He did pause, occasionally, to actually eat some of the food. He was hungry and it was fantastically delicious.

But he’d continue with his plate piling and vanishing until someone interrupted him.
