Who is Jo Davidson related to in Line of Duty?

Kate Fleming

While Jo and Kate (Vicky McClure) seem to have formed a romantic connection over the past four episodes, some viewers think they could actually be related.

“#LineOfDuty might sound like a daft idea but I'm wondering if Jo and Kate are sisters?,” said one fan.

A second added: “OMG!! I think it might be Kate (though I can’t remember if we know much about Kate’s back story) .. because do you remember Jo had that old photo of her and what looked like a sister? (despite saying she had no family)”.

Ryan Pilkington

After Jo and Ryan (Gregory Piper) seemingly shared some very suspicious looks in the latest episode, some Line of Duty fans think they could be blood relatives.

“OMG #LineOfDuty so is Jo Ryan’s mum or are Jo and Kate sister? Next Sunday can’t come soon enough,” wrote one person, while a second guessed: “Jo & Ryan: Auntie/Nephew or Brother/Sister.”

They added that Jo could be being blackmailed by Ryan to help with his undercover work for the OCG (organised crime group).

Andrea Wise

Hastings' boss Andrea (Elizabeth Rider) has seemingly been very keen to get rid of him this season.

After putting the poor fella on early retirement and announcing that she'll be cutting the anti-corruption budget by 90%, viewers are convinced she is a bent copper herself.

Someone guessed: “I think I’ve sussed it out. Line of duty theory, episode 4- Jo Davidson is related to the big boss, Andrea Wise.

“Remember Jo smashed the wine glass aimed towards a picture of a young girl and women hugging. Could Andrea be her mother?”

Tommy Hunter

Long time Line of Duty fans will remember Tommy Hunter as the first ever leader of the OCG (organised crime group) back in series one.

Tommy ended up agreeing to become a police informant for prosecution immunity and was transferred to police protection.

However, he was involved in an ambush in series two, which killed several police officers and put him in a critical condition. Tommy was later killed in hospital.

There are a few theories that Scottish Tommy could be her real father.

One person said on Twitter: “Steve said ‘he’ so I'm going with Jo is related to Tommy Hunter, it can't be a copper as would be on the database and all the other dead ones were coppers.”

While another chipped in: “I reckon she's Tommy Hunter's daughter - both Scottish? I think he's his daughter!”

Other potential relations could be Dot Cottan (Craig Parkinson) who was part of organised crime and tried to cover up a paedophile ring back in series 3.

Evil policeman Nigel Morton (Neil Morrissey) has also been suggested, as well as Mike Dryden (Mark Bonnar) who viewers will remember for his affair with Lindsey Denton (Keeley Hawes).
