Alyson was out partying. Kassy was expecting her to invite her. She didn't.
Kassy is not happy about that. While Alyson is trying to make some omeletts to combat her hangover, Kassy decides to trick her with a freeze remote. She stops her, switches certain ingredients, adds some extra stuff or just changes the placement of a on the cucumber mid cut.
Alyson thinks its her hangover mind playing tricks on her. Even as Kassy undresses her mid cooking she can't figure out whats going on.
