Well, she might. Sure, Clare’s motivations for such a betrayal remain unclear – perhaps she’s just doing what she thinks is best for Ryan – but there’s no denying that she is probably the person that Catherine trusts more than anyone, meaning she could probably pull this off without being suspected.

Then there’s Neil (Con O’Neill), who has been accompanying Clare and Ryan on their alleged football outings.

“I don’t know about Neil,” says Catherine. “I’ve never been sure about Neil.”

Hard same, especially as all we really know about Neil is this: he’s Clare’s friend-turned-live-in-lover, and he – just like Catherine’s sister – has his own demons, as he’s struggled with addiction over the years.

Other than that, he’s a bit of an enigma; we don’t know if his path has ever crossed Royce’s. But if he is involved in this, one has to wonder if he and Clare are working together… or whether he’s doing it behind her back, too?
