Married At First Sight UK fans have expressed their shock that Marilyse chose to stay married to Franky despite accusations of controlling behaviour.
Throughout the series, viewers had pointed out "red flags" in ex-military, Dubai-based personal trainer Franky's behaviour towards Marilyse after the pair were matched as strangers and thrown into a marriage experiment.
Viewers had seen him become aggressive when asked to open up on his feelings during the show's commitment ceremony, react badly to criticism from the other couples, and at one dinner party he told Marilyse "maybe don't talk when I'm talking".
But despite mum-of-two Marilyse appearing to distance herself from Franky during the final days of the show and discouraging him from returning to the UK after 16 years in Dubai, MAFS UK fans were surprised to see her choose to stick with him at their vow renewal ceremony in Wednesday's episode.
One person tweeted: "Blimey. I’m shocked at Marilyse. Did not expect that."
Someone else wrote: "Can’t help but think Marilyse has made a BIG mistake."
Another viewer added: "Eugh Marilyse why would you choose to stay with Franky, the man is a walking red flag."
At the vow renewal, Franky read out a poem about his feelings for Marilyse and told her that he loved her.
One viewer tweeted: "I'm gutted that Marilyse didn't dump Franky. That poem was the biggest red flag of all."
Someone else added: "Did Franky just say 'Well done you' to Marilyse for staying with him?"
Another person wondered: "I would LOVE to know what happens when Franky meets Marilyse's sons."
Less surprisingly, Matt and Dan also chose to stay together and put aside their differences on whether to live in Northern Ireland or Leeds.
Viewers were left on a cliffhanger over whether Amy and Josh would choose to stay together, and Thursday night's episode will also include decisions from remaining couples Tayah and Adam, and Morag and Luke.
