Trivia: When Pietro says he'll help the twins maximise their candy acquisition, one twin says "Kick-ass!" and Wanda repeats to herself "kick-ass." She sounds almost confused, but might merely be disapproving of the language, either way this is either a nod to, or who knows, maybe even may connect in-universe to the fact that both Aaron Taylor-Johnson, who played Pietro in Avengers: Age of Ultron, and Evan Peters, who plays Pietro in WandaVision and the recent X-Men films, both starred in Kick-Ass.
