Of all the Crawleys, Edith arguably goes through the most over the course of the series: being the overlooked, "plain" middle child; getting left at the altar; falling in love with a man she can't be with; having their daughter out of wedlock and finding out he died. That's why it's so nice to see her fall for Bertie, a genuinely kind man who appreciates her ambition and independence. Their seemingly smooth road to marriage is thrown when Mary spitefully tells Bertie about Edith's daughter before Edith herself has told him, leading to a broken engagement. It turns out that Bertie just needed some time to get used to the idea, though, because he apologises and re-proposes, finally letting Edith be the happy bride she's always wanted to be in the series finale. By the end of the first movie, they're expecting their own first child — and, as a bonus, with Bertie's unexpected inheritance, Edith actually outranks her entire family!
