Gavin and Stacey fans only just realising where they've seen Smithy's mum before

Warning: This article contains spoilers

The final episode ever of Gavin and Stacey aired last night in which it brought back a famous guest who people have only just realised played another well-known character years ago.

OH! And what an end to an era it was.

After the 2019 Christmas special, fans have been waiting for five long years to see the Barry and Essex gangs come back together for one final time, and once writers James Corden and Ruth Jones finally revealed that the 2024 episode would be the last ever episode, people were both equally heartbroken and excited.

With so much left unanswered in the last episode, surely 2024’s would clear everything up?

Like, did Smithy say yes to Nessa’s proposal?

What happened on that fishing trip?

Alas, while Smithy ultimately made the choice we were all hoping for and binned off that annoying Sonia, we never did get the full story between Bryn and Jason.

While we have been left hanging for the rest of our lives, there’s at least one mystery which has been solved and that’s: Who is Smithy’s mum?

Now, we had the return of the other Smithy during last night’s episode, and it was amazing to see Sheridan Smith as Rudy again one last time, but when she came accompanied by Cath Smith- his mum, immediately I recognised her.

So did a lot of people.

Played by Pam Ferris, it’s about time that everyone recognised the range that she can play.

Not only did she play a brilliant character in the murder mystery show Rosemary & Thyme, but she’s also fantastic in Call The Midwife and also features in Harry Potter and the Prisoner of Azkaban as Uncle Vernon's awful sister, Aunt Marge.

However, what she’s most remembered for is playing the character of Miss Trunchbull in Matilda.

That’s right, fans have figured it out and they’ve been left shocked.

A viewer wrote: “MISS TRUNCHBALL IS SMITHYS MUM?”

She is!

Another stated while pairing a load of exclamation marks: “PAM FERRIS IS SMITHYS MUM!!!!!!”

Lastly, a person nodded: “I'll never get over Smithy's Mum being Mrs Trunchbull.”

It seems like other viewers also realised her face was that of the scariest headmistress in history after re-watching the show following the 2019 special too, as some took to social media to rave about their discovery.

One person wrote: "Just seen on TikTok that Smithy's mum in Gavin and Stacey also played Miss Trunchbull in Matilda?!?! I'm literally SHOOK."

Another commented: "The fact that the same actress plays both Miss Trunchbull in Matilda and Smithy’s mum in Gavin & Stacey will forever blow my mind."

Someone else shared: "It still blows my mind that Miss Trunchbull from Matilda, Smithy’s Mum from Gavin & Stacey and Vernon Dursley’s sister from Harry Potter (the aunt he blew up) are all the same person."

Ferris is an absolute gem on the silver screen, and her credits in film are just as impressive.

Did you know that she was even in a slew of Christmas films, such as Nativity! and Saving Santa and also Luther.

Tidy.
