The mystery behind the Gavin and Stacey fishing trip was explained, but the scene was deleted before it aired.
The comedy set in Barry returned for a one-off Christmas special with more than 11 million people tuning in.
In the episode, Uncle Bryn and his nephew Jason came very close to revealing exactly what happened on their fishing trip.
Throughout the series it’s been hinted at but it’s always remained one of the show’s biggest mysteries.
During the Christmas special, fans thought they were about to hear what really took place that day, but just as Bryn was finally about to tell the cast what happened, he was interrupted by the children.
It’s now been revealed the show’s writers Ruth Jones and James Corden – who star as Nessa and Smithy – had originally planned to explain the fishing trip in series two, but ended up changing their minds about the idea.
Lisa Edwards, who owned the house the show used as uncle Bryn’s home, still has a script of the episode that millions of fans want to watch the most.
Speaking previously she said: “We have a script for an episode which was never aired.
“It was supposed to be Uncle Bryn and his nephew watching this VHS.”
She added: “They both watch it together to see what happened on the fishing trip. But they decided to not show the episode.”
Fans were once again left without an answer on what happened during the trip as the mystery continues to intrigue millions of viewers.
The special did appear to answer one of the show’s other mysteries – revealing how old Nessa is.
James and Ruth’s heartwarming creation became the most-watched Christmas special since 2008, and secured a 49.2% audience share, according to the BBC.
The Christmas special faced criticism for including the uncensored Fairytale of New York and for ‘ pushing the idea that cannabis is okay’.
Viewers criticised it for including the use of the homophobic term ‘f****t’ during a scene where Nessa and Bryn sing the classic Christmas song.
Then a peer whose son killed himself after becoming hooked on high-strength cannabis has criticised the one-off special for trivialising the dangers posed cannabis.
Lord Nicholas Monson’s son Rupert committed suicide aged 21 in January 2017 after developing drug-induced psychosis.
In a scene from the show, one of the characters, Dawn – played by Julia Davis – is teased by friends for worrying about her husband smoking cannabis after finding a joint in his car and branding him a “junkie”.
She told Pam and Mick, played by Alison Steadman and Larry Lamb, that Pete was, “a drug addict, addicted to drugs”.
When she shows them the joint she found in the glove box they laugh: “Is that it?” and tell her they used to smoke it all the time.
Lord Monson accused the programme of pushing a “strong subliminal message”.
He told the Daily Mail: “With much justification, the BBC prides itself as a beacon of truth but here it has a blind spot.
“Knowledge of the potential damage of modern cannabis is hardly obscure. What then is it doing, pushing a strong subliminal message that cannabis is perfectly OK and those who fear it might be otherwise are fair game for mockery?”
