TV Line caught up with Executive Producers Jonah Nolan and Greg Plageman and asked them which characters will return for the new season:
While at this time they would only offer up a “We hope so” when it comes to bringing back my old soap crush Paige Turco as Zoe, they were able to confirm other returns for Season 2 of last year’s most watched freshman drama. Jay O. Sanders will resurface as the D.C. bigwig codenamed “Pennsylvania 2,” Robert John Burke is back as Fusco’s NYPD pal Simmons, and Annie Parisse and Mike Kelly will reprise their roles as CIA operatives Kara Stanton and Mark Snow.
And their plans for new guest star Margo Martindale? They would only say their ideas for her character are "top secret."
