The second season of Blue Lights ended with thrilling moments, including a violent standoff in Mount Eden, a shocking murder confession, and even a hint of romance. With season three already confirmed, the finale sets the stage for even more drama.
The sixth episode of the Belfast police procedural answered the question of who would take the fall for Dixon’s murder, and gave us a sneak peek into what lies ahead for the Thompson family after young Henry discovered a crucial gun.

In the previous episode, Henry had fired a shot through the window of their Mount Eden home, which shattered the rear-view window of Grace and Stevie’s police car.
The finale picks up with the revelation that, while no one was harmed, the situation escalated into a tense standoff. Henry, still holding the gun, stood frozen as police tried to de-escalate the situation.
The Investigation Unfolds
Lee gets a tip-off via video and, using some clever editing, turns it into a sensational piece. The footage suggests Henry was surrounded by armed officers and makes it appear as though he was merely holding a toy gun.
The police react strongly, turning the Thompson house upside down in search of anything that could tie Henry to Dixon’s murder. Upon discovering that the gun wasn’t the murder weapon and was, in fact, legally owned, their investigation takes an unexpected turn.
As expected, the video stirs up trouble in Mount Eden. Tensions rise as locals clash with the police. A response team is forced to establish a cordon to control the increasingly agitated crowd, which retaliates by throwing petrol bombs at the officers.
Back at the station, things start falling into place when they realize the face mask worn by Dixon’s killer matches one found on the body of Ian ‘Soupy’ Campbell, a former military man. Lee Thompson had once asked for a similar scarf to honor their shared time in Afghanistan.
The scarf, found in the Mount Eden home, links Lee and Craig McQuarrie to the murder. With forensic evidence confirming the connection, McQuarrie confesses, but insists he acted alone, clearing Lee of any direct involvement.
New Relationships and Unanswered Questions
Or has Lee truly escaped? The episode concludes with something brewing at the Loyal pub. Though Lee seems to have evaded responsibility for Dixon’s murder, his sister, Mags, kicks him out of the community, accusing him of being responsible for the death of their uncle Rab, who died of a heart attack during the police standoff.

Back at the station, Murray’s questionable dealings are catching up with him. His backroom negotiations with shady characters to maintain peace have been exposed. A preliminary investigation is launched into the fact that Murray never officially recorded his visit to Lee at the Loyal. While the outcome of this investigation remains unclear, it’s obvious that Murray’s future is now in jeopardy.
With the investigation into Lee and the Dixon murder wrapped up, the Belfast police head to the pub to unwind, marking yet another crisis averted. Several new relationships are emerging, especially between Grace and Stevie, who decide to take their connection further after a kiss earlier in the episode.
Though the finale might feel like everything has been neatly resolved, we know Blue Lights will return for a third and fourth season. Could Lee Thompson make a comeback? Given that he’s never been officially implicated in Dixon’s death, there’s a strong chance we haven’t seen the last of him.
