A trailer for next week’s episodes shows Coco Stedman returning to the experiment to take care of ‘unfinished business’ – leaving her ex-‘husband’ Sam Carraro furious.

Sam looks furious as he stands up and storms out the moment Coco arrives.

Relationship expert Mel Schilling then says: ‘There is a lot of tension. There is a lot of unfinished business here.’

Sam and Coco were one of the first three couples to leave the social experiment.

They both elected to end their ‘marriage’ after their relationship failed to blossom and Coco’s affair with co-star Cameron Dunne came to light.
