Line of Duty may have come to an end (and we're bereft!), but even now, we're still finding easter eggs and teasers that we missed the first time round.
But while we now finally know who H is (it was bloody bumbling Buckells all along!), it seems another person was hiding in plain sight that we totally missed.
Check out the video below.
And his wife of five years, Tianna Chanel Flynn, actually popped up in one episode of Line of Duty in a blink and you'll miss it cameo.
In season five of the corrupt cop drama (which fans will remember sees AC-12 take on renegade cop John Corbett), Steve gets a text from a woman called Tina Watts on a dating app (hilariously called Deny or Reply asking to meet for a drink.
The singleton in question is actually Tianna, and the picture of the Staffie she's cuddling is their real-life pet too.
Sadly for Tina Watts, Steve chooses to deny - it's tough juggling catching bent coppers and having a love life, after all.
But it was a happy ending for Martin and Tianna IRL, as the pair live together Stateside after a lavish wedding ceremony in Glasgow back in 2016.
Naturally, Line of Duty co-stars Vicky McClure and Adrian Dunbar, who play other AC-12 detectives Kate Fleming and Ted Hastings, were in attendance.
While we're all hoping for there to be more Line of Duty in the future, a new series is yet to be confirmed - and Martin himself has suggested that this may have been the last we've seen of the department.
Speaking on the Shrine of Duty podcast, the unofficial podcast for the show which discusses fan reaction, theories and spoilers, the actor explained: "Jed [Mercurio, showrunner] always takes time after a series, like a couple of months.
"He likes to take the emotion out of it and sit down and looks at all that.
"There are different elements this year. Usually, we're just looking at - do people want us back, because you don't want to overdo it. But there's also - when you get 10 years in, you start to think of legacy, and if it goes down that well in some ways it might be the perfect ending."
Martin continued: "We won't do [another series] just for the sake of doing it. That won't happen. Jed will only do it if he feels there's a story there to be told."
Line of Duty is available to stream on BBC iPlayer.
