Marvel and ABC have released a new clip from the January 27th episode of "Agent Carter" entitled "The Blitzkrieg Button." No, it doesn't reveal Stan Lee's cameo, but it does provide some new details on Howard Stark's life.

In the 54-second video, Agent Carter confronts Stark over the lies he's told her. Stark claims he was only trying to protect her, and reveals facets of his childhood background to make her see why he felt lying was necessary.

The synopsis for "The Blitzkrieg Button" reads, "Peggy may be in more trouble than usual when fugitive Howard Stark suddenly returns for mysterious reasons. And Chief Dooley chases a new clue all the way to Europe that threatens to destroy Peggy's future at the SSR."

Marvel Entertainment has also released the official synopsis for "Agent Carter's" sixth episode, "A Sin to Err:" "Peggy discovers the shocking truth about Leviathan but doesn't realize that her true enemies are even closer than she imagined. Meanwhile, Souza is close to confirming the truth about Peggy and may just put her in the crosshairs of the SSR."

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