The Ring Master's orders were that every member of the Carnival was expected to give at least one 'good' gift to someone else. This is something of a challenge for Foster. After all, wouldn't the only 'good' gift from him be no gift at all?

Any present he could give to someone would be tainted by both the knowledge of and association with its giver's identity; and this even if he didn't manage to give something completely terrible, which he knows can be made at least somewhat possible by spending enough money.

Fortunately, he knows someone. Someone for whom the idea of a present from Foster would not be too viscerally revolting. Someone he doesn't loathe, or feel too reminded of how much he loathes himself around (sometimes.)

Someone who has a real affinity for garbage.

Amethyst.

Which is how she finds herself ambushed in her own doorway, with Foster shoving a package at her face rather forcefully.

It's even wrapped.

In meat paper.

"Here!"
