EastEnders viewers are certain they’ve uncovered a troubling secret about Teddy Mitchell—one that could put Zack Hudson in danger and potentially ruin his relationship with Sharon Watts.

EastEnders fans are abuzz with speculation that Teddy Mitchell is hiding a sinister secret, one that could tear apart his relationship with Sharon Watts (Letitia Dean) and endanger her brother Zack Hudson (James Farrar).
Since arriving in Albert Square last year with his two sons, Teddy (Roland Manookian) has remained a mysterious figure, with little known about him beyond the fact that he’s Billy Mitchell’s (Perry Fenwick) long-lost brother.
However, rumors have surfaced about Teddy’s questionable past, particularly concerning his eldest son Harry (Elijah Holloway). The pair confessed they fled Dartford for Walford to escape some kind of trouble.
Jack Branning (Scott Maslen) also discovered that Harry’s ex-girlfriend, Shireen, vanished years ago and is presumed dead—a mystery that is set to unsettle the Mitchells in the coming episodes.

On Monday (March 17), it marks four years since Shireen went missing, and tensions are rising at 1 Albert Square between Harry, Teddy, Nicola (Laura Doddington), and Barney (Lewis Bridgeman).
While at the Arches, Harry receives an unexpected visit from Shireen’s brother, Asad, who drops the bombshell that he no longer believes Harry was involved in her disappearance, according to Plymouth Live.
However, the Mitchells aren’t in the clear just yet. Asad shows up at Shireen’s vigil at Harry’s Barn, and chaos ensues when he accuses Teddy of murdering Shireen.
Harry quickly defends his father as Teddy denies the allegations. Meanwhile, Nicola is keeping a big secret about her and Teddy’s son, Barney—he’s actually Zack’s child, and she’s determined to keep Barney from finding out the truth.
But hold on, EastEnders fans are beginning to suspect Teddy might not be the innocent man he appears to be, and could be Walford’s next big bad. Is Zack in for a shock?
And what’s really going on with Teddy and Shireen’s disappearance? One viewer on X expressed their suspicions, saying: “I still think there’s something off about Teddy. He gives off serious psycho vibes. #EastEnders.”

Another fan is eagerly waiting for things to explode: “I hope that when Sharon finds out she slept with Grant and discovers Barney isn’t his son, it pushes him over the edge. I want this to be Teddy’s villain origin story. #EastEnders.”
Meanwhile, another fan is anticipating even more drama: “I wonder if we’ll see a much darker side to Teddy once Zack and Sharon’s secrets come to light. We saw him confront Ravi for dangling Barney off the bridge, but we haven’t yet seen his true dark Mitchell side. I’m hoping it comes out soon. #EastEnders.”
Another fan is dropping some chilling hints, saying: “Teddy will eventually discover the truth, and it will tear him apart.”
