LINE of Duty fans are convinced that a promo image "proves" Kate's fate following the show's deadly gunshot cliffhanger.
Viewers were left with the mother of all cliffhangers as hero cop DI Kate Fleming was locked in an armed stand-off with bent copper PC Ryan Pilkington.
In the latest instalment, Jo was confirmed as corrupt when she agreed to have Kate murdered to protect her own secret.
She called Kate and tricked her into meeting her at a disused warehouse car park and when she got there - Ryan stepped out and aimed at gun at Kate.
Last night’s thrilling episode ended with the sound of two shots being fired, leaving viewers wondering whether it was good cop or bad cop that had taken a bullet.
However, one eagle-eyed fan is convinced that Kate was not fatally shot after they spotted a yet-to-be-seen interrogation scene.
The photos showing Kate wearing a striking blue jumper was shared on social media by the creator Jed Mercurio in September.
The fan posted: "She will live! We haven’t seen this scene yet.”
So far Kate has not been involved in any such scene alongside Ted Hastings since she was transferred to the Murder Investigation Unit.
Vicky previously hinted that her time as a trio on the BBC One's most intense crime fighting drama may be coming to an end.
She said: “You know, nothing lasts forever. It will be a really sad time, it’s the longest standing job that I’ve ever had.
“As corny as it sounds, you know there is nothing nicer than working with mates... That’s really important. So, it will be a bloody great shame. I’ll keep going until I’m told to not.”
Other were convinced that Hastings and Arnott may have been in the firing line during the stand-off.
One fan posted: "Anyone else fear this is the last series of Line of Duty? Seems to be heading for a conclusion...I hope one of the main lot didn't get shot."
Another shared: "Please don't tell me that Steve or Ted were shot last night...could be a twist?"
A third added: "I reckon Steve was lurking in the darkness somewhere and he shot Ryan."
Meanwhile, DNA samples belonging to this series’ main bent copper Jo, were last week shown to link her to a sensational figure.
