The latest episode of Line of Duty had viewers trying to work out whether Supt Ted Hastings was dodgy after all.
There was concern from his pals and former/current colleagues Kate Fleming and DS Steve Arnott, when they made a discovery.
Steve found out in the episode that Hastings gave £50,000 of dirty money to Steph Corbett, which was an unlawful act.
His reasons are yet to be disclosed, while many fans came up with a theory or two.
Later on in the episode, he told Kate that he thought he knew the real reason why he handed over the cash - but viewers were not let in on the information.
Other things appearing to make Hastings look guilty were his refusal to arrest dodgy copy Ryan Pilkington, as well as him allegedly knowing that there was a rat within the OCG - as told by Lee Banks.
One other thing picked up on was the message Jo Davidson received from a mystery criminal in the OCG.
The word definitely had been spelled incorrectly - just in the same way that Hastings had done in the past.
Fingers started to point towards Hastings being guilty, after he was recently accused of being the mystery fourth 'H'.
Taking to Twitter, many viewers began to fear he was 'H' after all, and they were not happy.
One fan wrote: "If H is Hastings id actually be gutted ."
A second tweeted: "Noooo they are sooo going to go back down the H is Hastings route."
Another added: "No no no. Hastings cannot be H. Just no. There will be a national revolt."
A fourth said: "Hastings did spell definately on laptop."
Line of Duty airs Sundays at 9pm on BBC One.
