EastEnders aired a major twist this week, as Sonia's Fowler's father Terry Cant AKA Rocky was exposed an an imposter.
He is not Terry at all, and is in fact Thomas Cotton and a secret relative of troublemaker Dotty Cotton.
Dotty knows all about it, and has asked her Uncle Tom for help getting her grandmother Dot's inheritance money from Sonia.
Sonia was made Dot's power of attorney earlier this year, stopping Dotty from getting her hands on her grandmother's wealth.
Now, Dotty and Tom are secretly trying to fleece Sonia of the money - but fans believe there might be an even bigger twist on the way.
Of course viewers know Dotty is the daughter of Dot's late son Nick Cotton, also known as Nasty Nick.
It's thought Tom is a secret sibling of him, while this is yet to be cleared up with Tom never having been mentioned by anyone before.
Some viewers have questioned the family tree though, and are wondering if a paternity twist will tear Dotty's world upside down.
Many viewers recalled Dotty's mother Sandy Gibson is soon to make a return to the BBC soap, while details are being kept under wraps.
With Sandy and Tom both set to be in Walford at the same time, it would appear, some viewers are wondering if this will lead to another big secret being exposed.
Taking to Twitter, viewers questioned if Nick was Dotty's real dad after all, or whether Tom might actually be her biological father.
One viewer said in response to another fan: "I was thinking that Nick won't be Dotty's father. Instead, it will be Tom. That will throw Dotty's world into a tailspin."
A second fan tweeted: "Nick might not have been her Dad."
Another viewer wrote: "I think he likely is Dotty's real dad, we only had Nick's word he was Dotty's father."
EastEnders airs Mondays and Fridays at 8pm, and Tuesdays and Thursdays at 7:30pm on BBC One.
