Even Lyndsy Fonseca herself wasn't sure if she'd come back for "Agent Carter" Season 2, but we've finally got confirmation that the Angie Martinelli actress will indeed return.

The catch? It's only for a dream sequence. Speaking to Entertainment Weekly, EP Michele Fazekas confirmed that Angie will return in the ninth episode of the second season, and in this particular dream sequence -- which is described as an epic choreographed dance number -- she'll be "speaking the things that Peggy maybe can't say to herself."

On the dance sequence, Fazekas said, "It ties things back together from the first season and it's connecting all of these things in a way that only a dream can do."

Whether or not Angie appears in the series beyond that is a mystery, but who knows, maybe she'll make the trip with Peggy to the left coast someday...

Starring Hayley Atwell as the title character, "Agent Carter" returns with its second season on Tuesday, January 19 at 9 p.m. ET on ABC.
