EastEnders fans are convinced they’ve uncovered the true identity of teenager Tommy Moon’s mysterious friend Matt, and they believe Kat Slater should be seriously concerned.

EastEnders viewers think they’ve uncovered the identity of Tommy Moon’s secret online friend, and it’s clear that Kat Slater won’t be happy about it.
After spending months in care, troubled teen Tommy is back home, but his mum Kat is struggling to adapt.
Last year, Tommy was at the center of a harrowing storyline where he was violent towards Kat and his siblings.
Despite her pain, Kat remained silent about her son’s abusive behavior, which made Jean Slater worry about the safety of Tommy’s younger twin brothers.
Jean took action on her own and reached out to social services in secret, leaving Kat feeling betrayed by her family. Now, Tommy appears to have turned a corner and has made a new online friend.

In Monday’s episode, Big Mo left Tommy with his brothers, giving him an opportunity to apologize for his previous actions. However, when Kat returned home and found her sons unsupervised, she was horrified, which made Tommy feel even more alone.
Later, Tommy confessed his past mistakes, leaving Kat and Alfie feeling proud rather than fearful of their son, reports Plymouth Live.
EastEnders fans were left stunned this week as they connected the dots on a dark theory surrounding Kat’s son Tommy and his mysterious online friend Matt. The drama began when Kat (Jessie Wallace) apologized to her son and gave him a brand new games console.
As Tommy started chatting with his virtual friend, eagle-eyed viewers began to make the connection, speculating that Matt could actually be Kat’s long-lost son from the spin-off series Kat and Alfie: Redwater.

Rewind to 2017, when the BBC soap took us on a gripping journey to Ireland, revealing how Kat had secretly given birth to a son named Luke, who later became the deadly priest Dermott Dolan.
Viewers will recall the chilling final moment when Dermott almost drowned his mother at sea. But what ever happened to Dermott?
A clever fan on social media recently proposed that it could be Dermott, now in disguise as “DerMATT.” Could Tommy, unknowingly, be chatting with his own brother?

The speculation is running wild, with one sharp fan sharing on X: “Maybe I’m stretching here, but hear me out—Dermott, or maybe DerMATT! This whole ‘angel’ act Tommy’s putting on feels like it could be his vibe. #EastEnders.”
Another detective chimed in with: “What if Tommy’s secret online friend is Kat’s psycho son from Red Water? #EastEnders.”
A third viewer shared: “It would be great if Tommy’s mystery friend turned out to be his brother Dermott because Kat really needs a storyline #EASTENDERS.”
Another fan theorized, “‘Matt’ could be anyone hiding behind a fake name to protect their real identity.”
