Marvel has yet to announce Dominic Cooper for Carter's sophomore run, but Hayley Atwell (Peggy) is confidant that the playboy inventor will continue to have a presence as the story shifts to Hollywood.

"There will be repetition of characters," Atwell promised Den of Geek, even in light of her character's cross-country journey. "So Jarvis (James D'Arcy) and Howard will be there with us again. Yeah, we can't have a show without those guys."

Atwell had previously speculated that Jarvis' return would signify Stark's continued involvement, but the actress now seems more than a little certain.

Jarvis and Stark won't be the only members of the New York crew to return, however. Daniel Sousa (Enver Gjokaj) of the SSR will reappear, and fans are clamoring for Marvel to keep Angie Martinelli (Lyndsy Fonseca), Peggy's friend/love interest, in the loop.

At least two new characters will be introduced, according to E! Online, including a starlet named Wendy Fallon and a scientist by the name of Dr. Henry.
