Elsa had volunteered to help with something small, and that something small happened to be the drinks and ice cubes for those drinks. The ice cubes had taken a little trial-and-error before she'd finally gotten them into the shape she desired. The ice cubes had the shapes of various flowers, most notably roses, bluebells, tulips, and morning glories. Small, but it made her very happy to be able to do those without mishap.

She was going to be something of a wallflower, though. Not that she'd mind talking to people if they wanted to talk to her, of course! Unlike a certain son of Hades.
