'Call The Midwife's Overstuffed Season 12 Finale Is Equal Measures Joy & Tragedy

After seven episodes of serious and hard-hitting material, Call The Midwife lets it all hang out in the Season 12 finale. This episode’s focus is on the long-anticipated wedding of Nurse Trixie Franklin and Sir Matthew Aylward (now he’s inherited the baronetcy). Despite Trixie’s careful planning, almost everything on the big day goes pear-shaped. There’s also news about the future of Nonnatus House, under threat of demolition for so long, and a possible staff change.

It’s something that doesn’t distract me from the fact that I’m marrying you for you. Not a title or a name or any of the things that go with it.

Nonnatus’s expectant mothers’ clinic is invaded by another wedding party, who enter dancing the conga. Lizzie Yu (Rebecca Hyde), expecting a baby very soon, and Arnold Yu (Eric Mak) have tied the knot just in time, stopping by Nonnatus with all their guests in tow for her appointment. However, when Nurse Shelagh makes a house call with antibiotics for Lizzie, the following day, she can’t help but notice the friction between the two sets of parents.
