Call the Midwife viewers and critics saluted an emotional episode of the BBC One period drama, which had heartbreaking storylines for several leading characters.
Expectant mother Mrs Lunt was later diagnosed with Huntington’s chorea, an incurable inherited genetic disorder with a life expectancy of 20 years after the first symptoms.
Despite extra help from Nurse Trixie, Mr Lunt was unable to care for his two children and the newborn and the family were ripped apart by the condition.
At the end of the episode, Mrs Lunt had to let her children be taken away into care as she was sent to an institute.
Viewers praised the series for highlighting Huntingtons to a large audience.
This episode hit home in such a strong way however I'm happy that this terrible disease is being represented as it NEEDS more people to be made aware how heartbreaking and world crushing it can be.— ciara 🍏 (@asortofangel) February 4, 2018
Thank you from the bottom of my heart @CallTheMidwife1 #hda #huntingtons

Elsewhere, there was more heartbreak for Nurse Trixie has she pleaded with Christopher to return to his wife.
An emotional Trixie was seen returning to alcohol to cope with yet another painful break-up.
Meanwhile, the Turners new au pair Magda (Nina Yndis), took drastic action to get rid of an unwanted child and placed herself in serious danger.
The combination of these three harrowing storylines prompted many viewers to hail the episode as one of the show’s strongest of all time.
Well, #callthemidwife brings me to tears again. Magda has gone back to Paris, (Timothy must be devastated). Trixie still hasn't found happiness, (and is back on the sauce). And a family is devasted by Huntingdon's Chorea. This incredibly poignant drama is the best show on TV...— Clark Renney (@ClarkRenney) February 4, 2018
At 8pm the BBC announcer called #CallTheMidwife 'gentle' & 'nostalgia'. What followed was an hour of sheer, emotional terror, a series highlight - and that is REALLY saying something for this show. The full five buckets of tears out of five tonight.— Paul Martins Smith (@PaulSmith5783) February 4, 2018
I was in tears throughout that episode of @CallTheMidwife1. To see a woman so desperate she almost killed herself, because she couldn’t get the help she needed truly broke my heart. @NinaYndis did such a beautiful job of portraying such an immensely tough role. #CallTheMidwife— Beth | 11 (@downtondreamer) February 4, 2018
