Ending??

It's years later, but here goes:

After the verdict comes back as not-guilty, Peter goes into a kind of meltdown emotionally, because the trial made him feel inadequate and he feels responsible for everything Alice has been through.

He then tracks down the guy who raped her and he gets drunk in the same pub Ruddock goes to and just takes him outside and beats the daylights out of Ruddock.

Police comes to arrest Peter for assault at work, but at the police station the cops are clearly reluctant to charge him. They KNOW that the creep Ruddock who raped Alice got off the rap.

It's never spelled out directly, but certain hints tell us that the cops have had a "quiet word" with Peter's attorney and asked him not to confess to the beating.

The cops also have "had a word" with Ruddock and pretty much indicated that they thought he was a big wuss for letting a family man who works as a radiographer at the NHS beat him to a pulp right in the street in front of all his friends. (None of whom intervened, they just let Peter beat him up, which Peter comments on "you didn't try to stop me!") So. Another "passer by" fail.

So after the cops talk to Ruddock, he declines to press charges for assault against Peter.

From there Peter tries to resume his life and rebuild his relationship with his wife, who has said unforgivable things to him about his character and weaknesses.

Then in the last scene Peter is entering the train platform on his way to work and a young guy in a suit is arguing with his girlfriend; the argument escalates and when the guy grabs his girlfriend, we see other bystanders on the platform turning away trying not to notice.

But Peter just walks over to them and yells "HEY!!!!!!!!!!!!!!" and has a ferocious look on his face as he gives the guy a "stop it now" stare....then the last scene is a camera close up of Peter with that ferocious, no-nonsense look on his face and this is a face you wouldn't want to argue with!

But it's an ambivalent feeling at the end; yes Peter has now learned to stand up right away to bullies on a train platform, but the look on his face is SO mean and scary that you have to wonder what has been lost in the process.

Because earlier in the show, we see how affable and carefree he always was. Before the incident.

So now he's different for the better in one way, but perhaps not in others....
