The explosive finale of series six of Line of Duty aired tonight, leaving viewers with mixed feelings.

Millions across the UK tuned in to see 'H' – the high-ranking police officer aiding organised crime – finally unmasked.

Fans were also keen to see what happened to our favourite detectives – Arnott, Fleming and Hastings.

Some viewers were disappointed with the final episode as DI Ian Buckells confessed to being the man giving orders to kill police officers from behind a screen.

Whatever you thought of the final episode, there are still some unanswered questions that many will hope to be addressed in a seventh series.

Who is 'H'?

While Hastings seems to be satisfied that Buckells is his 'fourth man', viewers are not so easily convinced and many believe Buckells was just taking the fall so he wouldn't be killed by the organised crime group (OCG).

Some have indicated they do trust AC-12's new chief, Carmicheal as she is quick to dismiss any institutionalised corruption in the force.

Others don't believe Thurwell is dead in Spain and that could be a decoy to allow him to return should there be a seventh series.

And then there is Osbourne, who no one has liked since he tried to force DI Arnott to lie in court in the very first season.

Some believe that 'H' is still out there, ready for Fleming, Arnott and Hastings to hunt them down in series seven.

Will Kate Fleming return to AC-12?

At the start of series six we saw Kate had been redeployed and was looking into the death of journalist Gail Vella.

She had clearly made the move to try and spend more time with her son and work on her marriage.

But this had broken down again by the middle of the series.

Hastings made clear to Kate that she would be welcome back, even though at first he had been hurt by her leaving.

She later indicates to Steve Arnott that she would return, and said: "Someone has got to keep you in line."

Will Arnott pass his medical?

After one of the OCG's balaclava men threw Steve down three flights of stairs in series five, he has been suffering from chronic pain that he has been hiding from work.

Following routine drug tests, they picked up on his usually high amount of painkillers in his system.

He had to give back his gun privileges and blue light in his car until he is authorized again by the medical team.

While it seems he could do his work without these (he was seen using a taser in a scene in the finale) it could be possible that with time he could get back to a position where he could.

But, it could also make for an interesting sub-plot in series seven if he is on restricted duties.

Will Hastings be prosecuted for revealing John Corbett?

Hastings decided before he handed over AC-12 to Carmicheal that he would ease his conscience by telling her he was responsible for the death of undercover officer John Corbett when he told Tom Banks the OCG had a 'rat'.

Given Carmicheal's pragmatic approach to her work, it is hard to tell how she will proceed with this information.

If there is a series seven and she is 'H', as some say, she could use it to blackmail Hastings in the future or to discredit a later case against her.

What happened to the bent prison guards?

We first met the bent prison officers in series two when they poured boiling water on DI Denton's hands as a warning not to speak to AC-12.

They came back in the sixth series as they were about to lead DI Joanne Davidson to her death on a fake post-charge interview.

They were last seen being carted away in a police vehicle having been arrested at the scene.

Will Arnott continue seeing Steph Corbett?

Arnott has a habit of dating unsuitable women and Kate told the widow of John Corbett she was a 'person of interest', implying it was inappropriate.

He stated towards the end of the episode that he felt it wasn't a good idea to keep seeing her.

Perhaps she will have a bigger role to play in a seventh series given the £50,000 of cash Hastings gave her.

Did the PCC keep his job?

Rohan Sindwhani was seen to many viewers as an untrustworthy character who cared more about appearances than rooting out bent coppers.

But in episode six of series seven, he looked to be concerned about AC-12's future and said he was being pushed out.

With Cheif Constable Philip Osbourne still at the helm, it looks likely he will be pushed out and lose his job.

But did he pick up any secrets on the way that could help an investigation in series seven?

Whatever happened to the body under the garage in series 2?

Remember DI Lyndsey Denton was looking for Carly Kirk – the waitress exploited by Tommy Hunter?

Well, they had assumed they found her under the cement at a garage, but that later turned out to be another woman.

The identity of that woman has never been disclosed and some are still wondering if they will ever find out and how she fits into the plot.

Will there be a seventh series?

In the run-up to the series six premiere, Line of Duty creator Jed Mercurio was coy about discussing the future of his hit drama, telling Radio Times that the prospect of a continuation was uncertain.

He said: "We’re in a situation where it’s not entirely clear that there will be a seventh series.

“We would hope there could be. But we’re having to do our planning coming out of COVID, and a whole bunch of other things, around the idea that these things aren’t guaranteed at all now.”

Stars of the show Vicky McClure and Martin Compson were also quizzed about the future of the show by Jonathan Ross on his programme earlier this weekend.

Vicky said: “Genuinely don’t know. We don’t know anything, not just saying it for effect.”

Martin said: “That’s nothing different for us. Jed always takes months after… there’s stuff above our pay grade, analytics, figures and all that kind of thing that comes in. He always takes time off. But I think it is important to say, I think this natural story arc that we’ve been on for the last six years…”

Jonathan said: “That’s coming to an end.”

Martin said: “We won’t come back just for the sake of it. That’s for sure. We’ll come back if there’s a story to tell.

"But, so as well, if it ends well maybe sometimes it is best to leave it. But, so, genuinely we don’t know.”

After the success of the latest series bookies Paddy Power are anticipating at least one more season of the show, with the chances of a seventh instalment next year rated as odds-on.

Paddy Power is offering odds of 8/13 that series seven airs in 2022, and the news of further episodes could even be revealed straight after the end of this season’s finale at 2/1.

It’s a much longer 8/1 that mysterious bent coppers and complicated acronyms are no more, but if the BBC were to cancel the show, there’s a 2/1 chance that it launches a spin off series next year.

The current season is as short as 1/33 to win the show a National Television Award this year and is also odds-on to finally win a BAFTA at 1/12.

Once off duty, leading man Martin Compston is 8/1 to one day bag himself an Oscar, and is also 6/4 to join the cast of this year’s I’m A Celebrity… Get me Out of Here!

A Paddy Power spokesman said: “It’s been a tense few weeks all leading up to this weekend… or so we think.

"We still don’t know if this is the moment we finally learn H’s identity, and if we are made to wait another season to find out, I may or may not have to spend the next 12 months scouring fan forums to crack the case myself.”
