Call the Midwife's series six finale will include an emotional return for Emerald Fennell’s Nurse Patsy Mount, it has been confirmed.
The actress departed the show earlier in the series, when her character’s father fell ill. After Fennell posted a message on Twitter about her “glorious” time on the show, fans feared she might not return.
However, Nurse Patsy was referenced in last week’s episode and pictures have been revealed by the BBC of Mount reuniting with her partner Nurse Delia Busby (Kate Lamb).

Thank you all for your lovely  messages! What a glorious, beautiful thing to be part of. Lucky old me. ❤️❤️❤️

The emotional reunion for the two characters along with the highly anticipated wedding for Nurse Barbara Gilbert (Charlotte Ritchie) and vicar Tom Hereward (Jack Ashton) should make the series 6 finale a fan favourite.

Barbara and Tom’s wedding is fast-tracked due to her father, a canon, accepting a missionary post in New Guinea for the next three years, meaning he would not be able to officiate at her nuptials as planned.
Barbara and Tom, who became engaged during the 2016 Christmas special, cannot imagine their big day without her father there, so they endeavour to arrange the wedding in just three weeks before he sets sail.

So there’s a wedding, but what about babies?

Elsewhere, former nun Shelagh Turner goes into labour before wedding bells have even rung – but will everything go according to plan after her surprise pregnancy?
Actress Laura Main, who plays Shelagh, said she looked at birthing videos online to get into her role.
She told the Radio Times: ‘They haven’t been edited too much and it’s pretty difficult to watch! But the women have no inhibitions and they are very inspiring.
‘Women who are giving birth go into a zone, don’t they? You block it all out and just go for it.’

And the actress added filming the scene was a ‘very memorable day’ after the journey her character has been on.
She said: ‘After all, I started on the show as Sister Bernadette, a nun who thought she was infertile. And here I am as midwife Shelagh giving birth.
‘It was just lovely. And nice for me as an actress to play another massive aspect of life.
‘It makes me want to have a baby of my own.’
