FANS of The Traitors think that Harry may have made a 'fatal error' last night.
Throughout the tense episode, the army engineer was at war with fellow Traitor Ross.
Harry, 22, won the battle as Ross, 28, was banished by the group from the castle, which left fans fuming.
Before he left the infamous round table, the video director revealed that not only was he a Traitor, but he was also the son of Diane.
Enthusiasts of the hit BBC format - fronted by Claudia Winkleman - think that this may end up becoming Harry's downfall.
Fans think the real Faithful will eventually figure out that Ross would not have killed his own mum.

Meaning that they could think he was only recently recruited as one of The Traitors, and the spotlight of suspicion will fall on his main rival, Harry.
They took to X - formerly known as Twitter - in their droves as they expressed their theories.
One viewer noted: "Evie and Jaz realise that Ross would never kill his own Mum meaning he's only recently been recruited. The only time would be when Harry had a shield. And therefore Harry is lying. #TheTraitors."
A second thought: "How has literally no one mentioned yet how weird it would be for Ross to kill his Mum? #TheTraitors #TheTraitorsUK."

"THE EASTER EGG BEING WHY TF WOULD HE KILL HIS OWN MUM SO OBVIOUSLY HE WAS A RECENT RECRUITMENT #TheTraitors," exclaimed a third.
As a fourth explained: "Why didn't Ross say "recently recruited" when he left? This lot are dumb for not realising once he admitted his mum was Diane that he wouldn't kill her... so he was recruited... meaning there's more traitors left. #TheTraitorsUK #TheTraitors."
And a fifth fan added: "Cmon guys. put two and two together and realise Ross wouldn’t kill off his mum #thetraitors."
