The reality competition series "Celebrity Traitors" is poised for a dramatic upheaval as a "sensational bombshell" is expected to alter the course of the series just before its finale. This unexpected development comes after comedian Joanne McNally became the latest contestant to be banished on Thursday.

Last week's episode concluded on a cliffhanger, with the fates of Sharon Rooney and Joanne McNally hanging in the balance, dependent on Traitor Kenny's decision at the round table. The celebrities had previously selected Kenny to wield a "dagger," granting him a deciding double vote.

A TV insider revealed that the impending twist is one that "no one is likely to see coming" and was not predicted by the show's producers. "The likes of this has never been seen on the show before and may never be seen again," the insider told The Sun. This development is anticipated to make the semi-final episode a pivotal and unmissable event leading into the Friday finale.

Adding to the intrigue, BBC viewers noted that fellow Traitors had previously boasted about having "completed the game" due to being voted the "most trusted" in a challenge, which awarded them a special power. However, the show's dynamics in the Scottish castle are known for their volatility, with Michael Sheen having previously suggested contestants should reconsider their strategies after a series of "Faithfuls" were banished.

During a recent "field of screams" challenge, contestants worked in pairs to collect gold bags and hang them on pitchforks to bank cash. Three bags on a single pitchfork resulted in the scarecrow of a contestant blowing up, eliminating them from contention for a secret power. Traitor Kenny was awarded a dagger with a double vote, and the group added £13,500 to the charity prize fund, bringing the total to £59,500.

However, viewers expressed concern that the Faithfuls appeared to be struggling, as the contestants voted for the three Traitors as the most trustworthy individuals in the challenge. Online commentary reflected this sentiment, with viewers noting the Faithfuls' apparent difficulty in identifying the Traitors and predicting a likely win for the Traitor team this season.
