For the Coordinator!Emmet AU, when it comes to Ingo becoming the PLA protagonist's actual, legal Uncle, as cute as Emmet and Johanna meeting, getting to know one another, becoming friends, and then falling in love could be, it would be WAAAAY more funny if Emmet suggested it sheerly because he heard the kid refer to Ingo as their 'Uncle.'
Emmet hears "Uncle Ingo" and just thinks to himself, 'Uncle Ingo...? Hey, we can actually make that happen!'
The next day he runs up to Johanna just like, "Hey! So, hear me out. Let's get married! Why? Well, we are both single. No one would nag us to be looking for a partner or try to get with either of us when we're not interested. But also, 1: Tax benefits. 2: It would make it easier for all of us to get dual citizenship. 3: More excuses for all of us to get together. 4: The kid calling Ingo their 'Uncle' would become a factual statement. 5: We're all already practically family anyway. 6: Ingo and I will make sure that you and the kid will always be able to access the Unovan Subway system for free."
This is just an idea that absolutely tickles me.
