Coronation Street's Lydia Chambers may finally be exposed, if viewers are correct with their latest theory.
Some fans have predicted Sarah Platt or Adam Barlow will unintentionally rumble Lydia's plan to set up her ex Adam with a fake affair.
Adam is at risk of losing his job, and has lost his wife and his home as Sarah doesn't believe he is innocent.
But that could soon change, according to viewers who believe a forgotten prop on the ITV soap will be what brings her down.
Recent scenes on the ITV soap have shown Lydia confirming her revenge plan against Adam, after something happened in their past.
Adam has no idea why ex Lydia is so against him, but she suggested he knows more than he is letting on.
But some fans remembered the five-burner oven Adam bought Sarah for her birthday, which she hated, and many questioned if this might be linked to Lydia's downfall.
Recalling it had a camera in it, and it was in the flat, fans questioned if the random plot device might have filmed Lydia in the flat, or if it will do in the future.
This would possibly prove she had access to the flat without Adam and Sarah with her, and might even show her planting evidence.
Taking to Twitter, one theory read: "Remember the oven he bought Sarah with a camera in it to watch the roast cooking? That's going to come back and save the day. She was in the apartment right after that was mentioned."
As others shared the theory, another fan replied: "Yes I forgot that. Sarah needs to wake up and smell the roast beef!!"
A third viewer added: "I'm pretty sure that's what's going to save his bacon."
It comes as some viewers made a major prediction about Lydia's son Finn, who hasn't been seen or heard from since December.
Viewers began to predict her young son might be Adam's secret child, but now some fans are a little concerned about the fact she barely mentions him, and he hasn't featured on-screen in months.
With her true history with Adam yet to be revealed, some viewers have questioned if Lydia sadly lost a child, and maybe this is what she meant when she claimed Adam "messed up her life".
Others predicted Finn might not be Lydia's child, and perhaps she was pretending to have a son - while there was another theory that Lydia doesn't have full access to her child for an unknown reason.
Taking to Twitter after recent scenes, viewers shared their thoughts on her apparently missing child.
One fan commented: "Has Lydia actually got a son? Maybe the one who was at the Christmas Market wasn't really hers. Or he is but she only has limited access because she's an actual psycho."
Another viewer tweeted: "I don’t think she’s actually got a son or her son maybe died."
A third added: "Did we ever establish that Lydia doesn't actually have a child?" as a fourth fan wrote: "I thought that she might have borrowed him, like Grace did."
