Criminal Record Season 2 Episode 4 Ending Explained: Why Kieran Might Betray Cosmo Next

Criminal Record Season 2 Episode 4 finally tightens the screws, and I mean that in the best possible way. After Criminal Record Season 2 Episode 3 left Billy Fielding isolated from Cosmo Thompson’s gang because his escaped-convict status became public, Episode 4 shows why Daniel Hegarty’s risky move may have had method behind the madness.

Billy gets closer to Cosmo, June Lenker tries to protect the truth from a racist media storm, and a doctored photograph gives the wrong people just enough ammunition to muddy the waters. The episode, titled Safe, premiered on Apple TV on May 13, 2026, and it pushes the British crime thriller into nastier political territory. 

Cosmo’s ‘Nobody Died’ Lie Gets Dangerous in Criminal Record Season 2 Episode 4

Criminal Record Season 2 Episode 4 begins with Cosmo Thompson enjoying the attention that comes from poisoning public conversation. His claim that nobody died at Suffolk Square has become a rallying cry for racists and conspiracy peddlers. He suggests Rohaan Hussain may not even be real, and that the government is using the tragedy to vilify white people. It is ugly, and the writing is smart enough to show how quickly an absurd lie can start dressing itself as ‘just asking questions.’

June Lenker and JP are disgusted, but they react differently. June has lived long enough inside a biased system to understand how exhausting this fight is. JP, meanwhile, is visibly furious, especially when DS Kim Cardwell treats Rohaan’s family with chilling indifference. Cardwell’s old bigotry has not gone anywhere, and his casual cruelty gives the episode one of its bitterest edges.

The police try to push back by arranging a press conference with Rohaan’s mother, Zaynab Hussain. June and Sonya convince her to speak publicly, and Zaynab brings proof of her son’s life and death. Her anger is justified. Her pain is raw. But one small detail gives Cosmo fresh material. Zaynab keeps touching her ear because of a ring under her hijab, and Cosmo twists that into a claim that she is wearing an earpiece and being fed lines by officials.

That scene made my blood boil because it shows how facts can lose when bad faith talks louder. Even worse, the episode reveals Cosmo was partly right about one thing. The protest photo was edited, though not for the reason he claimed. Authorities removed a white protester carrying a child because publishing a minor’s face raised legal concerns. Their intent was procedural, not conspiratorial, but the bad editing left uneven lighting, and that mistake hands Cosmo a useful half-truth.

June’s Personal Life And Hegarty’s Plan Complicate The Case

June’s personal life does not get much peace either. She returns to counselling with Leo, hoping to repair some kind of co-parenting balance for Jacob, but the session turns into a painful exchange. Leo accuses her of failing to understand Jacob, and June reminds him through tears that Jacob is not his biological son.

Later, Leo tries to soften things, but June has already crossed another line with JP. Their attraction has been hovering for a while, and Episode 4 finally lets it happen. I do not read this as simple romance. June is lonely, angry, and professionally trapped. JP is also emotionally untethered, and he keeps giving June crucial information about Hegarty’s side of the investigation.

That is significant because JP tells her about Marco Rivelli and the doctored image scandal. June may genuinely want JP, but I do think she understands that he gives her access to things Hegarty will not. The show does not make her saintly, which is why she remains compelling.

Meanwhile, the knife Billy found in The Depot is confirmed as the weapon used to kill Rohaan. The handle has been wiped clean, but camera footage shows Kieran panicking when he cannot find something in his locker. It seems obvious that he hid the knife there, but Hegarty raises another possibility: Kieran may have been hiding it for someone else.

Then Marco Rivelli enters the frame. He is an ex-army man from the Royal Regiment of Fusiliers, and the police later find suspicious bombmaking materials linked to him, including large amounts of ice, metal nails, and other ingredients. Hegarty may still be slippery as an eel, but this time his suspicion appears to have teeth.

Criminal Record Season 2 Episode 4 Ending Explained

Criminal Record Season 2 Episode 4 ending puts Billy Fielding in immediate danger. Cosmo takes him to a private pier and starts grooming him for a possible terrorist attack. He flatters Billy by comparing him to a so-called revolutionary figure from his childhood, but it is clear that Cosmo sees him as useful muscle, not an equal.

Billy carries a burner phone from the police, and Hegarty follows close enough to learn where the explosives and stolen detonators are being kept. The police now have a real chance to recover them, though the show wisely stops before giving us the clean win. In Criminal Record, if something looks too easy, someone probably forgot to check the back door.

The bigger threat comes from Kieran. After realizing the knife is gone from his locker, he studies news footage from Suffolk Square and spots June in uniform. He then remembers seeing her during the operation when Billy was caught by Hegarty’s team. That is the click. Kieran now understands that June is police and that Billy is likely the mole.

The key question is whether Kieran tells Cosmo. I do not think he will do it immediately. Kieran may be hiding his own role in Rohaan’s murder, and revealing Billy’s cover could expose why he had the knife. That gives Billy a small window, but it is a thin one. Kieran may confront him privately first, and that could be more dangerous than Cosmo knowing everything.

Episode 4 is the strongest Season 2 chapter so far because it stops circling the danger and starts letting it bite. Cosmo’s propaganda is vile, Billy’s undercover position is wobbling, and June’s messy choices make her feel more human, not less capable. If Episode 5 follows through on Kieran’s discovery, Billy could be in serious trouble. So, do you think Kieran will protect himself, expose Billy, or turn on Cosmo first?
