Coronation Street fans are wondering if there is something Lydia Chambers is hiding, after noticing her son Finn has appeared to vanish.
Recent scenes on the ITV soap have shown Lydia confirming her revenge plan against Adam Barlow, 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.
Viewers began to predict her young son Finn, who appeared in an episode in December, 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.
Some fans joked he had been forgotten about, given when Lydia trashed her own flat recently to set up Adam, Finn was nowhere to be seen.
She also hasn't been seen with him for ages, nor has she mentioned him, while viewers have been led to believe that Lydia has been out in the early hours of the morning plotting against her ex.
This has sparked a new theory though, with some fans convinced Finn might not actually be Lydia's child.
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."
