*WARNING: MAJOR LINE OF DUTY SPOILERS BELOW*
Nigel is now doing interviews and fans are shocked about how different he looks in real life.
Speaking to BBC Breakfast on Tuesday about the intense final episode, Nigel had long curly hair and a beard which is quite a stark contrast to Buckells' clean shaven face and trimmed barnet.
One fan, who was clearly in awe of Nigel's curls, tweeted a "curls appreciation post" with a very clever nod to Ian's secret identity. "As it's late and no one can judge me: tHis is a Nigel Boyle hair appreciation post #LineOfDuty," she said.
A second viewer theorised that Nigel must have had an "identity change" because he looked so different from Buckells.
A third Twitter user said: "He looks totally different!"
Another wrote: "Buckells already demonstrating his new identity in witness protection."
When quizzed about a possible seventh series by presenters Louise Minchin and Joy Kay, Nigel was careful not to spill any new details. He said: "I don't know, that would be a question for an officer at least ranked higher than me."
When asked specifically if there was going to be another series, he replied: "No comment. I mean I honestly don't know, I hope there is personally but I honestly don't know."
There 'definately' seems like there's still a lot of stories left to tell after the big reveal at the end of series 6. Ian was caught out when Chloe Bishop (Shalom Brune-Franklin) pinpointed the now infamous misspelling, 'definately', throughout all the reports he had written.
For some fans, the reveal was quite disappointing, with some likening it to the Game of Thrones finale. Some fans expected a more looming figure as H instead of one of Buckells.
However, some fans have deduced that Line of Duty's big 'reveal' was fake all along - and pointed back towards a scene earlier this series. You can read more about that here.
While writer Jed Mercurio and the rest of the haven't said much about the future of the series, BBC Chief Content Officer, Charlotte Moore, has given an update about Line of Duty's future.
"Addictive event television, Line of Duty has kept the nation guessing for the last seven weeks, so it's no surprise that last night's jaw-dropping finale set a ratings record," she said in a statement.
"Jed Mercurio is a master of his craft, and I would like to congratulate him and the entire cast and crew for delivering such an incredible drama series.
"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."
