However, just when Grace is beginning to wrap her head around all the revelations which have been thrown her way, Jonathan makes a reappearance and tries to convince Grace he wasn’t involved in Elena’s murder. He admits the pair did have an affair – and that he saw her on the night she was murdered – but that he’d stormed out after the pair had had an argument about her obsession with Grace and Henry, only to return to find her bludgeoned to death.

Despite Jonathan’s insistence that he’s innocent, the episode comes to a close as Grace breaks down and calls the police, pleading them to come and arrest her husband. Talk about a rollercoaster, right?

If the second episode of The Undoing has left you with more questions than answers (including “how does Nicole Kidman’s hair look so good?”), you’re not alone. But don’t fear – Stylist’s junior digital writer Lauren Geall is here to try and unpick it all.
