Call The Midwife star Georgie Glen was left terrified about appearing on Friday's Lorraine, for fear of letting anything slip about Sunday's series finale.
Millions of hearts were left in mouths last weekend when the penultimate part of the new series ended with a devastating train crash that no-one saw coming, including Georgie and she's in the cast!
Fans of the smash hit BBC drama were left aghast in the closing moments of the episode when a train carrying popular characters Sister Julienne and Doctor Turner, played by Jenny Agutter and Stephen McGann, hurtled off the tracks as its driver suffered a medical emergency.

Before viewers had a chance to comprehend what they'd just seen, credits rolled, leaving them all fearing the worst in the run up to what is sure to be an emotional Call the Midwife finale on Sunday.
A teaser for the episode appeared on screen as Georgie, who plays Miss Higgins, joined stand-in Lorraine host Christine Lampard, herself shaken by the scenes, in the ITV studio.
And it was then that Georgie confessed she was terrified of spilling the beans.
As Christine remarked: "We know Nancy is hopefully OK, Sister Julienne and of course Doctor Patrick are the ones's we're worried about," Georgie replied: "I'm terrified I say anything that gives anything away!
"I've had the riot act read to me. I've got to be very careful what I say, but obviously that drama will continue to unfold, erm, throughout the final episode."
She added: "It has repercussions throughout, because everyone has to put their fears to one side, roll up their sleeves and get on; leave their personal worries aside.
"And Sister Hilda is dealing with a delivery over at the maternity home and knows nothing about.
"That is the lady who's the wife of the train driver."
