As the evening wears on, Greta might start to notice a tall dark-cloaked figure watching her through the crowds.

There's nothing visible of his actual features; the black hood covers his face, and he's wearing black gloves with carefully-stitched white bone patterns on his hands. These are folded carefully around the handle of a tall, wicked-looking scythe. That's...probably just a prop, right? Something to sell the costume?

He's always just standing still and looking at her when she sees him. Never moving. But he does seem to be getting closer.
