Call the Midwife fans in the UK were sent on a rollercoaster of emotions as the final episode of season 12 aired, with births, deaths and marriages all playing out. 

Viewers couldn't wait to see Trixie Franklin (Helen George) get her happy ever after as she tied the knot with Matthew Aylward, but as always in Call the Midwife, there was a devastating twist that left everyone stunned. 

So, what happened in the Call the Midwife season 12 finale? Here's everything you need to know...

*WARNING — spoilers for all of season 12 ahead*

Who died in the Call the Midwife season 12 finale? 

While viewers cried happy tears watching Trixie get married, there were also tears of sorrow as a sad death hit Poplar.

As all our Nonnatus House favorites headed to the church to watch Trixie become Mrs. Alyward, Shelagh Turner, Dr. Patrick Turner and their son Timothy (Max McMillan) raced to catch up with them after being delayed attending to a drama with a new mother.

However, disaster soon struck as they drove to the wedding when an expectant mother was involved in a car crash on the way to the maternity ward. 

In devastating scenes, fans watched as Dr. Turner declared mum-to-be Lizzie dead as soon as she was dragged from the smoking car and was forced to perform an emergency c-section in the middle of the road to save her unborn baby.

But the heartache didn't end there... as Lizzie's helpless husband watched on as his daughter was born, Shelagh talked deceased Lizzie through the birth, describing what her daughter looked like just as she would to any other patient.

Does Trixie get married to Matthew?

Yes! Trixie finally got her fairytale ending after years of heartache and tied the knot in a lavish wedding ceremony with all her friends and family around her. Her brother, Geoffrey made a special appearance for the big day, and when a series of disasters threatened to ruin Trixie and Matthew's wedding, including a fire that broke out at their fancy wedding reception venue, he teamed up with Nurse Crane to get Trixie's wedding back on track. 

While we will have to wait for season 13 to find out what the future holds for Trixie now that she has moved out of Nonnatus House, we do know that she and Matthew will have an exciting marriage... 

"It'll be interesting to see where they end up living," Helen told us. "But one thing is for sure, it will be a passionate marriage. They really challenge each other — I don't think they're just going to be playing house and buying lots of kittens!"

What happened to Sister Monica Joan in Call the Midwife season 12?

Sister Monica Joan is a retired midwife in her 90s, and while she is still harboring a bit of a feisty side, this season has also seen her battling loneliness and contracting a very serious case of hepatitis that was doing the rounds in Poplar. 

Viewers were left concerned for her welfare when she became very poorly indeed, even turning down food and her usual trip to evening prayer. But thankfully, as she always does, Sister Monica Joan managed to rally, and not only did she get well enough to go about her usual daily routine, but by the end of season 12 she was back to full fitness and delivering a heartfelt reading at Trixie and Matthew's wedding. Hurrah!
