When Agents of S.H.I.E.L.D. returns next Tuesday, we know that Aida (Mallory Jansen) is going to be trouble. Before the winter Hiatus, we got the first real view of everything that she has been up to, with the revelation that the Agent May (Ming-Na Wen) who had been interacting with the team was actually a Life Model Decoy (LMD). Today, a new teaser for this next “pod” in the fourth season was released, with a very menacing tone.

Meanwhile, another character who was introduced this season also has plenty of secrets to reveal, even if he isn’t a robot. According to Entertainment Weekly, we’ll be learning more about Jason O’Mara‘s Director Mace in the upcoming episodes.

Director Mace’s true agenda will start to be unveiled as we discover what’s really going on with him in the upcoming episodes. “There’s a general question with him in terms of being all about trust,” EP Jed Whedon says. “‘The team that trusts is the team that triumphs!’ A guy who is always saying that who is new and that smiley who has a secret, it’s hard to trust him. Even in episode 8, he started asking questions about the Darkhold. I don’t think it’s totally clear where he stands.”

We should learn a lot about Director Mace in the coming episodes especially considering the second episode after the show returns is titled “The Patriot,” which fans will note is Mace’s alter-ego in the comics. With so much focus on these new characters, it almost seems like a different show is returning this winter. What are you looking forward to the most? Let us know in the comments!

Agents of S.H.I.E.L.D. returns on ABC Tuesday, January 10th, at 10 Eastern. Make sure to tune in!
