Warning: Potential spoilers ahead. Catch up on season one here.

Simon Foster portrayed by Bertie Carvel

At the beginning of season one, Simon appeared to be the perfect husband.

He was a successful property developer that still found time for his wife Gemma, son Tom and his sick mother.

When Gemma became suspicious of what he was up to, her investigations revealed Simon to be having an affair with a younger woman.

After the affair was made public (quite explosively) Simon fled for London with his pregnant mistress, Kate Parks, in tow.

Now two years later, Simon, Kate and their young daughter Amelie have had a change of fortune and are returning to Parminster.

It is clear that Simon still hasn’t gotten over the way Gemma dealt with the affair.

What exactly is his game plan?
