It's only been back on our screens for a few weeks, but already fans are convinced they're about to see one MAJOR plot development in this series of Line of Duty.
New PC Ryan has appeared in the show since the first series, when he was linked to the OCG and part of a team that tied up Steve and nearly cut off his finger.
So, it's fair to assume that after grilling him after his involvement in driving a police car off the road which resulted in the death of the police officer driving, Kate may be in danger.
And fans have taken to Twitter to share their views on this plothole, we REALLY hope doesn't come true.
One fan said: "Why do I get the feeling Ryan's going to go after Kate at some point #LineOfDuty."
While another wrote: "I've an awful feeling Kate is going to die in #LineOfDuty. She knows too much and Ryan knows she's on to him. She took Dot's confession as well. I'll be distraught if this pans out."
And a third noted: "Looks like Kate might need to watch her back from now on."
Meanwhile, another fan said they'd be really annoyed if the theory turned out to be right:
"I'd be really p***ed off if that little s***e Ryan kills Kate," they said.
And we really hope the fans are wrong about this!
Line of Duty is now in its sixth series, after first airing on the BBC in 2012.
The popular show is set around anti-corruption unit AC-12, whose main aim is to catch "bent coppers".
Starring Martin Compston, Vicky McClure and Adrian Dunbar, this series focuses on DCI Joanne Davidson, a possible bent copper who may or may not have links to the OCG.
Could any of these lead to the capture of H? We'll have to wait to find out.
The sixth series of Line of Duty is now airing on BBC One, with the next episode due to drop at 9pm on Sunday evening.
