Fans were sent into a state of concern and further speculating what will happen in Sunday's tense Call The Midwife finale, thanks to a tweet sent from the show's official account.
BBC viewers were already up a height and fearing the worst after the end of last week's episode when a train carrying popular characters Sister Julienne and Doctor Turner was involved in a horrific accident, after the driver suffered a sudden medical emergency.
The terrified faces of the Sister and Doctor as the train hurtled out of control quickly became ingrained in the minds of those who tuned into the show, with its fraught final moments becoming the number one topic on Twitter as credits rolled.

And, with just hours to go until Sunday's series finale, the Call the Midwife account posted a picture, with an ominous sounding caption, that quickly sparked a reaction from fans.
The picture, which didn't featured all of the cast, came with the words: "UK fans - #CallTheMidwife Series 11 concludes tonight. How will Nonnatus House survive this?"
And it was the fact that the caption alluded to the House having to deal with a tragedy that worried followers, as well as the absence of some of the show's main protagonists from the photo.

"She and Dr Turner are missing I was convinced undiagnosed head injury for nurse corrigon would be the casualty... hurry up 8pm."
A second reacted: "Not ready for this tonight but I wonder is there significance the chair at the table is empty? Sister Julienne."
Predicting the finale will be full of tragedy, a third tweeted: "I’m already worried about someone dying in it!"
And, clearly well stocked up on tissues in preparation, another commented: "I'm not ready either. Got plenty of tissues ready..."
