'EastEnders' fans have been told that Michael Moon (Steve John Shepherd) will be part of a very dark storyline in the soap this summer.
Warning: spoiler alert!
The Daily Star says that although the entrepreneur is dating Roxy Mitchell (Rita Simons), he will become obsessed with her married sister Ronnie Branning (Samantha Womack) - going through her clothes and watching her while she sleeps.
He then convinces Roxy to dress more like her sister and meddles in the marriage of Kat and Alfie Moon (Jessie Wallace and Shane Richie).
A source said: "Everyone knows Michael has a mean streak, but he is set to get a whole lot worse.
"He's trying to meddle in as many people's lives as possible. It seems he wants Ronnie all to himself. But what exactly is he up to?"
