Emmerdale - Marlon Dingle catches Rhona Goskirk and Pierce Harris getting very cosy.

Rhona has decided to throw caution to the wind by starting up a relationship with Pierce in the absence of her estranged husband Paddy, despite Vanessa trying to warn that he has an ulterior motive for being in the village.

Although Pierce tries his best to win over those who are closest to Rhona, Vanessa remains disturbed by the relationship and tells Marlon that Pierce has even broken into her house to find information on Tess's death.

Concerned for Rhona and Leo's safety, Marlon immediately vows to confront Pierce - but his timing isn't great as Pierce and Rhona have just returned from a romantic lunch.

When Marlon bursts in and finds them kissing on the sofa, will he feel betrayed on behalf of his best friend Paddy?
