Line Of Duty's much-anticipated sixth series came to its conclusion on Sunday night with the identity of the elusive criminal 'H' finally unmasked.
Viewers were noticeable underwhelmed to learn that the elusive criminal was DSU Ian Buckells, who had been originally imprisoned after appearing to have been framed by Davidson due her being blackmailed by the OCG.
However, the episode's end failed to offer any resolution on whether the fan-favourite team of DI Steve Arnott, DI Kate Fleming and Superintendent Ted Hastings would return, ending on the revelation that the team has 'never been weaker.'

Having learned of Hastings' impending retirement, Steve is clearly torn on whether to pursue fears that he could be H, and after confiding in Kate, admits he's been involved in John Corbett's widow Steph.
After AC-12 discovered the OCG's workshop, they found a strong box hidden under the floor, which is revealed to contain an array of weapons used in murders investigated by Hastings and his team, including the gun that shot and killed Gail Vella, and the knife that slit the throat of DS John Corbett, who was killed by the OCG in series five.
It's the breakthrough that the team have been waiting for, as the box finally proves that Carl Banks was responsible for Vella's murder before being killed by the OCG himself.

After weeks of incessant emails, Steve is finally called in for a meeting with Occupational Health, who note that while he hasn't broken the law through his excessive painkiller use, he should take time off from his duties.
To no surprise, Arnott refuses, but does agree to hand over his fire-arm, and comes to clean to Hastings about his drug use. To his, and the viewers' surprise, Hastings doesn't dismiss him, simply saying: 'I'm glad you're getting some help.'
Despite fans' theories that Thurwell had to be alive, it is revealed that he was killed in the previous episode, and had actually been dead for several weeks when his body was found after being strangled.
DC Chloe Bishop, also reveals that any communication involving Thurwell and the OCG had been re-routed through Spain from a device in the UK, meaning the fourth man was definitely still amongst the corruption team.

Who is it? It was at least revealed that the so-called fourth man was actually DSU Ian Buckells, who had been originally imprisoned after appearing to have been framed by Davidson
After being imprisoned for her own corrupt behaviour, Davidson is taken away in a police van under the ruse she's being interviewed at Hillside Lane, but in reality it's the same criminal who strangled Lakewell several weeks earlier.
It's clear that H is involved in the attempt to kill Davidson, as the order for her transfer boests the same 'definately' misspelling, as well as the forced signatures of Fleming and DS Chris Lomax.
Luckily AC-12 reach the van in time to rescue Davidson, and vow to get her into witness protection if she comes clean on H's identity.
Jo is clearly reluctant to give up the man in charge of the Order who kept her hostage for so many years, and so AC-12 opt to return their investigation to former Chief Superintendent Patrick Fairbank but find nothing in his cell.
Once again Fairbank claims he 'doesn't remember' anything related to Davidson or the OCG, with a clearly-frustrated Hastings storming out of the interview.
Proving to be the clue that will crack open this decade-long mystery, Bishop spots the same 'definately' spelling inside a written note found in the records related to Lawrence Christopher's murder.
The case was being investigated by Vella before she was murdered, having learned that the botched work corrupt police officers meant no one was ever charged with the racially-charged crime.
As AC-12 debate whether to go public with the information, Hastings finally confesses to Kate and Steve about the mystery bag of money he gave to John Corbett's widow Steph, admitting he gave her the cash as a kind-hearted gesture.
He also fiercely denied revealing Corbett's identity as an Undercover Officer to the OCG, which eventually lead to his death.
Regardless, the written note finally sets the stage for the most important police interview in the show's history, with the stage set at last for Hastings to confront the criminal H who has caused so much havoc in AC-12.
The so-called Fourth Man is then revealed to be Buckells, despite perceptions hinting he was easily-manipulated and thus
