Obsession ending explained: what happens to Anna and William?

We enter into the finale on the same surprise episode 3 commute William has taken to get to the apartment where he meets Anna at. But unbeknownst to him, his son Jay is following him after his father hurriedly left his stag do.

He follows his father up to the steps of the building, calling his mother Ingrid (Indira Varma) to ask her whether she knows where William is tonight. We then see that William is now inside the apartment going up to an awaiting Anna who is blindfolded.

When Ingrid presses Jay on the phone to tell her what’s wrong, he doesn’t answer and instead takes the open door as a sign to run upstairs. He goes up to the top of the staircase, hearing moans from the other side of a front door and when he forces it open, he’s shocked to see his father and fiancée having sex.

William immediately looks up and Anna pulls her blindfold off, but when William walks up to Jay, Jay backs away out of the apartment. He’s visibly disgusted and continues walking back, his hand slipping off the rail – and he falls to his shock death.
