Billy stormed out, and Teddy encouraged his father to talk things out with him and build bridges.

Stevie apologised to Billy for everything, but he revealed that he had been with Teddy for over 20 years, which left Billy furious that Teddy hadn’t been around for him and his kids.

Billy refused to listen to his dad and told Stevie that he wanted him and his family to leave immediately.

Meanwhile back at the house, Phil also demanded that the new Mitchells leave, and tensions rose between him and Teddy.

Just what is Stevie hiding, and what is the truth about Teddy’s mum?
