Call The Midwife viewers' are still reeling in the aftermath of Sunday's episode, after a train crash left Sister Julienne and Doctor Turner's lives hanging in the balance.
And they've issued a warning to BBC bosses about the fate of the two popular characters.
Following a tear-jerking episode a week earlier, which saw actress Laura Main praised for her performance as Shelagh, the penultimate instalment of the new series had a very dramatic end that no-one saw coming.
Call The Midwife addicts watching on BBC1 saw their jaws hit the floor as the train Sister Julienne and Doctor Turner were travelling on came off the rails.

The fan favourites, played by Jenny Agutter and Stephen McGann, were returning from a conference along with young nurse Nancy Corrigan when the train driver suddenly suffered, what looked like, a brain haemorrhage.
As a result, the train raced through several red signals, eventually colliding with another train, before careering off the tracks.
The train crash happened in the closing moments of Sunday's show, meaning that after witnessing the horrific scenes, viewers will now have to wait a week to find out if Julienne and Dr Turner survive.
Still reeling from it the morning after, another took to Twitter to write: "Today everyone is talking about the super bowl and all I can think about is last night’s train crash on call the midwife,."
It was also still playing on another fan's mind, who tweeted: "Last night's call the midwife was terrifying ,with the train smash and carnage. Brilliantly filmed and acted."
And fans have taken to Twitter to preempt the anger should either Sister Julienne and Dr Turner, or both of them, die.
One tweeted: "Don't you dare kill off Sister Juilenne or Dr Turner! #CallTheMidwife That was like an episode of Casualty, could just feel the impending doom," with another writing: "There maybe riots if Dr Turner or Sister Julienne don't survive. #CallTheMidwife won't be the same without either of them."
A third posted: "Will only accept tragic ending to call the midwife if it means Paul McGann or Jenny Agutter is going to be the next Dr Who."
Referring to famous actress Jenny, another remarked: "If #CallTheMidwife kill off an actual Railway Child in a train crash I'm going to lose it
Other viewers who caught up with the episode on Monday were also aghast at what they saw, with one fan commenting: "I need a week off to recover from call the midwife. Just caught up and I’m an emotional wreck already. God help me next week."
