Perhaps the most disturbing and vivid tale in Coldwater is that of Tommy, played by Ewen Bremner. Initially, he seems to be a welcoming and devout neighbor to newcomer John and Fiona, who are new to the Scottish village. His wife, Rebecca, serves as the local pastor, making the couple appear deeply integrated into the religious and social fabric of the community.
As the season goes on, however, the pretence wears off. Tommy's charisma is a disguise for a more sinister personality, and by the end of Season 1, he's the Coldwater Killer. His actions and the consequences of his actions fuel the entire dramatic span, building to a tense, violent conclusion that leaves his destiny in question.
Who is Tommy in Coldwater ?
Tommy is first introduced as the social, chatty type with an unorthodox sense of humour. To the visitors like John and Fiona, he seems friendly and dependable, the type who upholds the values of the close-knit society. His religious devotion and good manners with Rebecca help to consolidate his status within society.
But Coldwater gradually reveals a different side of him. Tommy possesses an ominous past full of savagery and sadism, such as animal cruelty. His behavior suggests something horribly evil behind his glamorous image, and he is one of the show's most complicated and manipulative villains.
Tommy's obsessions and crimes
Tommy's character is developed as a result of his fascination with serial killers and true crime. It is not curiosity, but it informs everything he does and drives his dual existence as the Coldwater Killer.
Over the course of the season, it is shown that Tommy has been stealing "trophies" from his victims. These are jewellery, trinkets, and the collar off John's cat, Harlequin. His foster daughter, Moira-Jane, plays a key role in uncovering this evidence.
In finding his hidden stash, she is the provider of the evidence that will be needed to convict Tommy of his crime.
Manipulation and control
Throughout the course of Coldwater, Tommy bullies others into keeping him in ignorance. He accuses John of violent crimes, gossip, and rumors to ostracize him from everyone else in town. His plan succeeds for most of the season, with John being in danger and no longer trusted by others.
His wife, Rebecca, is not passive in the whole adventure. She is very active in creating suspicion against John, typically through religious practice and sermons that tint the impression of the community. Tommy and Rebecca are a facade of moral righteousness but evil at heart.
The climax: Kidnapping and confrontation
The tension slowly builds to a climactic point when Tommy kidnaps John and puts him in the trunk of his car. This thoroughly destroys the last remnant of his neighbourly nature, revealing his entire violent side.
The subsequent fight is complicated and fierce. Tommy attempts to make John kill him, an effort to switch the roles of offender and victim. There is a struggle, and while fighting, William breaks into the struggle. In the meantime, John is shot but survives.
This consequently exposed Tommy publicly as the Coldwater Killer, putting an end to his concealment behind deception.
Tommy's fate in Coldwater
As the episode closes, it can be seen that Tommy is guilty. William takes responsibility for what he did and reports to the police. Tommy can escape before the police arrive, though. As opposed to most crime shows in which the criminal gets caught or gets killed, Coldwater releases him and lets him loose, at least temporarily.
This not-straightforward conclusion creates more suspense for the story. Tommy's confession destroys the town, but his absence ensures that his shadow continues to haunt the village.
Aftermath and open questions
The final shots are then cut weeks later. John survives and gets over his injuries, and is seen out in public with Fiona, and normalcy is restored partly. Rebecca remains in the village, her complicity in Tommy's actions left unexplained, although morally abhorrent.
Tommy's former prayer group still meets, a sign that the influence he had not yet dissipated. There are questions: Will Tommy get caught? How will Rebecca cope with the truth? And can Coldwater village ever fully move beyond the betrayal of Tommy?
Tommy's story is the one involving hypocrisy, a religious neighbour on the surface, a manipulator and killer within. All his interest in serial killers, all his memorabilia, and conning John resulted in the unspooling of a mystery.
Tommy is exposed but not apprehended at the end of Season 1, freeing him. His flight, along with Rebecca's and the town's open-ended moral dilemmas, makes his own future uncertain and haunting as a Coldwater thread.
