Criminal Record Season 2 Ending Explained: Who Killed Leo and Why Was June Targeted?

I have enjoyed Criminal Record because it rarely takes the easy road, and its Season 2 finale proves that once again. Going into the final episode, Cosmo Thompson was already behind bars, which usually signals victory in a crime thriller. Yet this series knows that arresting the architect does not stop the machine he has built. Last week, Criminal Record Season 2 Episode 7 ended with Cosmo exposing Billy as an informant and deliberately getting himself arrested, leaving his followers free to carry out a horrifying terrorist attack across London. Episode 8 picks up from there and turns into a race against the clock, with June Lenker and Daniel Hegarty trying to stop a disaster before innocent lives are lost.

What makes the finale effective is not the ticking-clock suspense but it is the cost. While the police manage to prevent catastrophe on a city-wide scale, June pays a devastating personal price. By the end, the victory feels bittersweet, and the show leaves viewers with an uncomfortable truth: even when the good guys win, somebody still gets hurt.

Criminal Record Season 2 Finale: How June Lenker and Daniel Hegarty Uncovered The Terror Plot

At the beginning of Criminal Record season 2 finale, the police have Cosmo in custody, but they still lack the one thing they desperately need: the exact targets. Documents recovered from the safehouse provide fragments rather than answers. Maps, notes, online searches, and extremist material suggest an attack is imminent, yet nothing points to a precise location. Meanwhile, Cosmo’s followers have already left the safehouse and begun moving into position.

The interrogation scenes become the episode’s strongest material. Cosmo initially behaves exactly as viewers would expect. He mocks the detectives, dismisses the evidence, and pretends his extremist fantasies were merely content for his livestream audience. Then he pivots to intimidation, insisting that his movement will eventually become powerful enough to replace people like Hegarty and Lenker. For a while, it appears he might hold out. Then the detectives find his weak spot.

Instead of focusing solely on prison, they force him to consider something he never anticipated. If foreign citizens die during the attacks, international governments could become involved. Suddenly, Cosmo is not imagining himself as a political martyr. He is imagining extradition, lifelong imprisonment, and potentially even harsher consequences abroad. The bravado evaporates almost instantly.

It is one of the finale’s most satisfying moments because it exposes Cosmo for what he really is. Beneath all the speeches and slogans stands a coward desperately trying to save himself. Eventually, he reveals the targets: East Ham Halal Market, the Clairmont Hotel, and the Immigration Centre at Moorgate.

Criminal Record Season 2: Why Cosmo Betrays His Own Followers

One of the episode’s most fascinating developments is how quickly Cosmo abandons the people he claimed to care about. For an entire season, he has presented himself as a leader, a visionary, and a defender of his followers. Yet the moment his own future becomes uncertain, he trades them away without hesitation. The deal he demands is astonishing. Cosmo wants immunity not only for the current case but effectively protection from future prosecution connected to his actions. June is understandably horrified. From her perspective, they are rewarding a man responsible for organizing a terrorist attack.

However, the alternative is worse. Without the information, hundreds of people could die. This moral compromise becomes one of the finale’s strongest themes. The show asks whether justice sometimes requires making deeply uncomfortable bargains. There is no neat answer.

Yes, the attack is prevented, although not without bloodshed. Cosmo’s followers collect backpacks containing powerful explosives and head toward their designated locations. Their plan is frighteningly simple. Leave the bags in crowded areas, retreat to safety, and trigger the explosions remotely. Fortunately, the police begin closing in. Andy becomes the first to fall when his nervous behavior attracts attention. Armed officers confront him before he reaches the market, and he is killed after refusing to comply.

Phil and Nigel manage to reach the Immigration Center, but the authorities have already evacuated much of the building. Tactical teams move in quickly, killing both men before they can carry out the attack. Kieran’s story is more complicated. After arriving near the Clairmont Hotel, he senses something is wrong. The location feels suspiciously empty, and panic begins to take hold. He briefly contemplates another horrific act involving the school where he works, but ultimately he cannot go through with it.

Instead, he surrenders. That decision makes him the only member of Cosmo’s group to survive. The result is a complete victory from an operational standpoint. Every bomb is recovered. Every target is secured. The coordinated attack fails. Yet the episode refuses to end there.

Criminal Record Season 2: Who Killed Leo?

Criminal Record Season 2 finale’s most shocking moment arrives after the crisis appears to be over. Leo Hanratty finally calls June with a painful decision. He has accepted that their relationship cannot be repaired and wants her to move on. The conversation is uncomfortable, emotional, and unfinished. Then everything changes. Leo’s car explodes and the blast kills him instantly before he can say anything more. The series never explicitly identifies the killer, but the implication is fairly clear. Someone connected to Cosmo’s extremist network likely targeted June.

Earlier in the season, her image had circulated among members of the group. She had become a visible enemy of their cause, a police officer directly responsible for dismantling their plans. Leo was simply in the wrong place at the wrong time. That is what makes the moment so tragic. The attack was almost certainly intended to hurt June, but the people responsible had no idea her relationship with Leo was already collapsing. Their goal was revenge. Instead, they murdered an innocent man.

Is Cosmo Thompson Really Free at The End?

On paper, yes. Six weeks later, Cosmo appears surprisingly comfortable. His extremist platform continues attracting followers, and he is treated as a public figure by supporters who remain unaware of his role in the bombing plot. It is infuriating. However, appearances can be deceptive. The police have seized his passport, limiting his movements. More importantly, Hegarty appears determined to use Cosmo rather than simply release him. The arrangement feels less like freedom and more like a leash.

Cosmo may believe he escaped consequences, but he remains trapped inside a system that is watching his every move. The finale wisely avoids presenting this as a clean victory. Dangerous ideas do not disappear overnight. The threat remains, even if the immediate crisis has ended.

Is Cosmo Really In Love With Billy?

Criminal Record season 2 finale strongly suggests that he is. Throughout the season, Cosmo repeatedly showed unusual concern for Billy. In the final episode, that concern becomes impossible to ignore. When speaking with Hegarty, Cosmo asks about Billy and only Billy. He does not care about the other members of his organization. He barely acknowledges Kieran, who is now sitting in prison. His attention remains fixed on Billy. Whether viewers interpret those feelings as romantic, obsessive, or something in between is open to debate. What is undeniable is that Billy matters to him in a way nobody else does.

Ironically, the only person Cosmo genuinely seems to care about is the one who betrayed him. Criminal Record Season 2 ends with London saved, a terrorist network shattered, and June Lenker more broken than ever. That combination gives the finale genuine weight. It understands that triumph and tragedy often arrive hand in hand. Will Billy eventually find his way back to Cosmo? Will June discover who was truly responsible for Leo’s murder? And can Hegarty really keep a man like Cosmo under control forever?
