Hollyoaks - Harry Thompson will reveal Pete's true colours in wedding day showdown.

Harry takes action when he discovers that his ex-girlfriend Cleo McQueen is having an inappropriate relationship with the villain.

As Pete's wedding day dawns, he finds it increasingly difficult to keep Cleo quiet about their secret as she once again threatens to tell Reenie the truth.

Pete drags Cleo into the village's alleyway to talk her round, but Harry witnesses the suspicious exchange and wants answers when he sees that his ex is upset.

When Harry gets some time alone with Cleo, he's stunned as she tells him the truth about her relationship with her stepfather.

Just as Reenie and Pete are declared husband and wife in a low-key ceremony at The Dog shortly afterwards, Harry bursts through the doors and reveals Pete's secret to everyone.

Cleo's older sister Porsche has no doubt that Harry is telling the truth given her own experience with Pete, but who will everyone else believe?
