On February 16, "Agent Carter" will air two episodes -- "Life of the Party" and "Monsters" -- back-to-back in a two hour block. In a handful of new photos from the episodes, Peggy enlists the help of Dottie Underwood so that she and Jarvis can crash Calvin Chadwick's party, and Vernon Masters holds a meeting with one of Whitney Frost's allies. The episodes promise more conflict between Peggy Carter and Whitney Frost.

"Life of the Party" - When Peggy realizes she cannot save Wilkes on her own, she turns to her most unexpected adversary for help while Whitney makes a move to control the deadly Zero Matter.

"Monsters" -- As Peggy plots a rescue mission, Whitney hunts for even more dark power; and Jarvis learns he should not make promises he cannot keep.

Starring Hayley Atwell and James D'Arcy, "Agent Carter" airs Tuesdays at 9 pm ET/PT on ABC.
