BBC viewers spot 'alarm bells' in The Split Barcelona's dramatic first episode

As BBC's The Split returns, eagle-eyed fans were quick to spot 'alarm bells' in its dramatic first episode.

Some even foresee a 'punch up' before new limited series conlcudes with its second instalment.

After a two-year hiatus, The Split has made a stunning comeback, captivating audiences with the splendour of Barcelona.

Nicola Walker, acclaimed for her role in Unforgotten, reprises her part as Hannah Stern alongside Stephen Mangan as Nathan, and sisters Nina and Rose played by Annabel Scholey and Fiona Button.

Deborah Findlay graces the screen once more as the matriarch Ruth, with Ian McElhinney dazzling as Professor Ronnie. The Split Barcelona cast also includes Kobna Holdbrook-Smith as Glen Peters, Elizabeth Roberts as Liv Stern, and Alex Guersman as Gael.

On Sunday (December 29), the first episode of this two-part limited series aired, leaving viewers gasping at a shocking plot twist amidst what was meant to be Hannahs daughter's picture-perfect wedding.

The teaser for this one-of-a-kind series hints at an enthralling voyage: "Two years on, formidable family lawyer Hannah Defoe and her family are back and have gathered for a beautiful wedding at a magnificent vineyard nestled in Catalonia's wine region. Set across one sun-soaked weekend, there will be break-ups, reunions and, like all good weddings, plenty of romance.

"As the sun rises over the glorious Spanish countryside, Hannah is compelled to banish the ghosts of her past and open herself up to the possibility of love again. Can she find the courage to take the leap into a new future?"

Fans were quick to sense trouble during the wedding festivities, as one viewer remarked: "Groom and groom's family heavy wedding means alarm bells."

The twists came thick and fast: Hannah's ex Archie showing up already engaged wasn't the only shocker. It soon emerged his betrothed was having an affair with the father of the groom, reports the Mirror.

Speculation was rife about potential showdowns, with one fan asserting: "Oooh, I bet it's going to kick off in a minute." (sic)

Another eagerly anticipated some fighting, commenting: "Oh wonder if we'll get a Archie and Nathan punch up?"

Excitement for the show's climax mounted among viewers, with comments like: "Oh I have missed this. Shenanigans under Spanish sun, Nicole Walker drinking. Blimey, she can put it away. Twists. Turns. Prenups. The DRAMA. Superb cast and writing. Lets not waste time, we need another London outing." (sic)

The Split: Barcelona continues Monday, December 30, at 9pm on BBC One and BBC iPlayer.
