Line of Duty unanswered questions after series 6 – Kate with AC-12 to Carmichael

Line of Duty fans were left on the edge of their seats as they watched the nail-biting final episode on Sunday.

The identity of the mysterious H was finally unveiled after years of speculation, with DCI Ian Buckells exposed as the man behind the link to the organised crime group (OCG).

However, some viewers were left scratching their heads as some questions were left unanswered after the finale.

They were left disappointed when Buckells confessed to being the "fourth man" as many suspected someone else was the villainous character.

Viewers also hoped to find out more about what happened to Steve Arnott, Kate Fleming and Ted Hastings.

It's hoped that there will be a seventh series so more questions are answered.

Is Patricia Carmichael corrupt?

  • Line of Duty's creator Jed Mercurio shares cryptic post after BBC show's finale

Patricia Carmichael became known as one of the main villains of the programme as fans were suspicious that she was up to something.

Detective Chief Inspector Carmichael, played by Anna Maxwell Martin, attempted to prove Ted Hastings was "H" in series five and after that the pair didn't see eye-to-eye.

After Sunday night, fans were left baffled as it wasn't revealed whether Carmichael was a bent copper or not.

Is Buckells really H?

  • BBC seems to confirm Line of Duty series 7 amid speculation of show's future

H was unmasked to be DS Ian Buckells during tense scenes, but many viewers refuse to believe the revelation is real.

Some believe Buckells was just taking the fall so he wouldn't be killed by the OCG, while others think he's confessed so the real H is free to carry out more corruption.

One viewer tweeted: "Erm there's got to be another series…. Buckells can't be H? He's a puppet not a top dog?!”

Another wrote: "Buckells was really H, why was he shaking in prison, why did they bring Lakewell in to him to show him what happens to rats, sorry I'm not buying that he is really H, series seven is coming in my book."

"I have just been thinking Buckells is not really H he is just taking the rap as he knows AC-12 is no more and the corruption can carry on," penned a third.

Will Kate Fleming return to AC-12?

  • Line of Duty's Ian Buckells star addresses speculation over series 7 of BBC show

At the start of series six, fan-favourite Kate Fleming had been moved to another team away from AC-12.

She had been redeployed and was investigating the death of journalist Gail Vella.

Fans then saw Hastings tell Kate she was welcome to return, even though he was disappointed that she left in the first place.

At the end of Sunday's finale, Kate hinted to her colleague and close friend Steve Arnott that she would return as she said: "Someone has got to keep you in line."

Fans are hoping they'll get to see her back with AC-12 if there's a seventh series.

Will Hastings be prosecuted for revealing John Corbett?

  • Line of Duty Ian Buckells star Nigel Boyle looks totally different in real life

At the end of Sunday night's finale, Ted Hastings handed over AC-12 to Patricia Carmichael.

He decided to tell her he was responsible for the death of undercover officer John Corbett when he told Tom Banks the OCG had a "rat".

It wasn't revealed whether Hastings would face any consequences after his admission.

Some say that if Carmichael is in fact "H", she could use Hastings' confession to blackmail him if there's another series.

Will Arnott pass his medical?

  • Line of Duty fans convinced ‘H’ identity is fake after spotting blunder in show

Steve was thrown down three flights of stairs during series five and he's suffered from chronic pain ever since.

Following routine drug tests, his employers picked up on the unusually high amount of painkillers in his system and he was forced to give back his gun privileges and blue light in his car.

Fans are curious to find out if Arnott will pass his medical and get his privileges back, but this would only be revealed in another series.

Will there be a seventh series?

Fans are currently speculating whether or not there will be another Line of Duty series.

In March, Jed admitted that he "doesn't know" if there will be a series seven.

He told The Radio Times: "We don't know. Since probably season four, we've been talking to the BBC about the realistic longevity of the series.

"I've experienced broadcasters pulling the plug while we were still developing a storyline – Bodies and Cardiac Arrest both ended prematurely on the BBC. So it's an ongoing discussion, is all I can say."

Jed added: "We're in a situation where it's not entirely clear that there will be a seventh series.

"We would hope there could be."

However the BBC Chief Content Officer today suggested a seventh series was on the cards.

Charlotte Moore said: "I'm looking forward to having a conversation with the team about where we go next and what the future of the series might be."
