"I read somewhere once, that all good stories start with a wedding"
No you didn't. There is no known historical literature that says such a thing. This is lazy writing, by someone who needed to legitimise their own quote, by saying "Someone else once said it, or wrote it". Trying to legitimise a poor conceptual opening premise, through a lineage of "unknown origin"
This is the same as saying "I heard from someone ..." then inserting your own concept, belief or lie, so you can't be questioned or called out on its legitimacy
This it that liars do, when they want to promote something they don't know is true, as if it were true
"Someone told me that ..." without offering "who" is the same as saying "I know this probably not true, but I want to tell you anyways"
In this case, it's borrowed authority used to drive a poorly driven narrative
Next scene
Enola is established as the one who needs save Sherlock
Then in the next scene, she established as Mary Sue Correcting Sherlock, to show that she is undoubtedly smarter and more competent that Sherlock
Making her instantly unlikable, as she lacks any relatability or room for growth
Then in establishing the relationship with her fiance, she makes it clear he is only there to suit her. To the point where her dialogue denegrates him as not being important enough that she would care what his first name is "Yes, he has a first name. I was surprised to". It supposed to illustrate he wants to marry her, cause she is great. But he is barely important enough to her, to warrant knowing his first name
