January Jones played Emma Frost in 2011’s X-Men: First Class and with X-Men Apocalypse set to hit theaters next spring, does she have plans to return to the multibillion-dollar franchise?

“I don’t have another one in the books, but I think Emma died … but she’s a mutant,” Jones said when she stopped by the Entertainment Weekly Lounge at Comic-Con in San Diego on Saturday along with her Last Man on Earth castmates. “They’d have to give me a long heads-up though, because I don’t really like to work out,” she joked.

Jones is definitely returning to Last Man on Earth next season, however, which creator and star Will Forte won’t say much about: He claims he doesn’t know if they’re going to be introducing anyone new — but isn’t ruling that option out, either.

“That’s the fun thing about this show,” he said. “If you ever really get in a rut, you can introduce a new character.”

Watch Forte, Jones, and Kristen Schaal talk more about the Fox comedy above.
