LOOK: "Marvel's Agent Carter" Uncovers a Musical Number

New images from "Marvel's Agent Carter" provide a look inside the mind of everyone's favorite Strategic Scientific Reserve agent

Arriving courtesy of TV Insider, the images reveal part of a musical dream sequence from Tuesday's double-episode event, which includes a guest appearance by Lyndsy Fonseca as waitress/actress Angie Martinelli.

In "The Edge of Mystery," Peggy Carter (Hayley Atwell) and Chief Daniel Sousa (Enver Gjokaj) propose a trade with Whitney Frost (Wynn Everett), while the SSR gets help from Howard Stark (Dominic Cooper) that may be the key to eliminating Zero Matter. That's followed by "A Little Song and Dance," in which Peggy desperately tries to save Dr. Wilkes (Reggie Wilson) with a danger plan to stop Whitney Frost. However, Thompson (Chad Michael Murray) makes a surprising move that could destroy them all.

"Marve's Agent Carter" airs Tuesday at 9 p.m. ET/PT on ABC.
