WandaVision's fourth episode dropped today and it featured the long-awaited return of Kat Dennings as Darcy Lewis. Dennings first appeared in the Marvel Cinematic Universe in 2011's Thor and has not been seen in the franchise since 2013's Thor: The Dark World. Fans have been very excited to see Dennings return alongside Randall Park, who is reprising his role as Jimmy Woo from Ant-Man and the Wasp. In honor of their return, Twitter has given each character their own emoji. Dennings took to the social media site earlier today to express her excitement over the tiny Darcy.
