The beloved Irish matriarch may face her toughest moment yet, as the hit BBC sitcom prepares to sign off after more than a decade on air.

Brendan O’Carroll has confirmed that Mrs Brown’s Boys will take its final bow at the end of September — but not before delivering a shock that could leave fans in tears. The 68-year-old comedian, who created and stars in the show as the foul-mouthed but loveable Agnes Brown, revealed the last episodes will contain an “emotional goodbye” unlike anything viewers have seen before.

“We’re giving Agnes the send-off she deserves,” O’Carroll told The Irish Sun. “It won’t just be a farewell — it’ll be a thank-you to all the people who’ve supported us. But I’ll warn you now: people should be prepared for something big.”

That “something big” may be a storyline no one expected. According to insiders, Agnes Brown could suddenly fall into a coma and be rushed to hospital in a scene that will leave audiences stunned. In a tense moment, doctors are said to debate whether to switch off her life support, hinting that the sitcom might actually kill off its iconic leading lady.

The twist — unprecedented in the show’s history — has sparked furious speculation among fans. Could Brendan O’Carroll really say goodbye to his alter ego in such a devastating way? Or is this all a clever fake-out to keep audiences guessing?

Social media is already ablaze with theories:

“If they kill off Agnes, I’ll never forgive them — she’s the heart of the show!” one fan posted on X (formerly Twitter).

“This better be a dream sequence… I can’t handle Mrs Brown actually dying,” another wrote.

The upcoming episodes will mark the end of an era for the BBC hit, which began as a radio show and stage play before becoming a ratings juggernaut on television. Known for its unscripted gags, frequent corpsing (when actors break character from laughing), and outrageous humor, Mrs Brown’s Boys has become a Christmas tradition for millions of viewers worldwide.

But Brendan O’Carroll insists the finale won’t just be about shock value. “This is for the fans who’ve been with us since day one. Agnes has been part of people’s lives for years, and we wanted to give her an ending that’s memorable, heartfelt, and a little bit mischievous — just like her.”

Whether Agnes Brown lives or dies remains tightly under wraps, but one thing is certain: when the final curtain falls, it will be anything but ordinary.
