The preview video hints at the aftermath of the crash, with Megan Cusack's character Nancy Corrigan saying worriedly to Cliff Parisi's Fred Buckle: "I don't know where they are, Fred!" before Dr. Turner's son, Timothy, can be heard stating to his mum Shelagh (Laura Main): "Mum, Dad and I weren't speaking," before she replies: "That can't be helped now."
It seems fans were feeling the stress thanks to the teaser clip. One person wrote in the comments section: "The stress this caused me," as a second added: "Hope we don't lose Doctor Turner and Sister Julienne. I look forward to Sunday evenings best program that comes on please don't end," followed by a sad-face emoji.

A third wrote: "I'm not ready to say goodbye to anyone in the show, much less Dr Turner and Sister Julienne," while a fourth agreed and said: "Just watching this is heartbreaking! I hope they survive. The show wouldn't be the same without them... x."
The penultimate episode also sparked a major reaction after it aired the devastating train crash. A fan summed up the response on Twitter, writing: "Nope. Dr. Turner can't die. He and Tim have to go into practice together, and he has to grow old with Shelagh telling him off about sneaking a crafty pie. And what will Poplar do without the best GP in London? #CalltheMidwife."
Call the Midwife concludes on Sunday at 9pm on BBC One.
