The new series of Motherland left viewers struggling to comprehend how lead actress Anna Maxwell Martin could star as both Line of Duty's scheming DCS Patricia Carmicheal and the comedy's frazzled middle-class mother, Julia - because they're so different.
The first episode of the third series of Sharon Horgan's BBC2 show sees Julia unravel as she sparks a nit outbreak at her children's primary school - and is forced to live under Covid-esque restrictions.
Viewers tuning in struggled to compute that Maxwell Martin, 44, could go from playing icy DCS Carmicheal in the Line of Duty finale to the hysterical Julia.
Last night's installment saw the London mum screaming into a towel at the thought of her elderly mother residing permanently in her family home.

Admitting that she was surprised at how vindictive her character turned out to be, she explained: 'There were a couple of bits [in the script] where she was nasty and I just went for it. And then she morphed into a horror show.
'I think she’s just misunderstood, she’s just trying to do her job. She probably just wants a nice cuddle, Pat. She’s just a bit cross.'
She insisted that her role is no reflection on her actual personality, saying people are surprised at how nice she is in real life compared to her character.
Motherland Writer Sharon Horgan's latest creation took fire at the Government's handling of the pandemic - but replaced Covid with an outbreak of nits.
Viewers on social media said they 'could relate' as the comedy's key characters were forced into a bubble of isolation after central character Julia refused to use nit shampoo on her two children.
Motherland airs at 9pm on Mondays on BBC1 and is available on the iPlayer
