The character of the last fic you wrote meet their Canon counterpart. What do they say to each other?
In the process of writing a fic just like this, which makes for funny interactions and it makes me wonder how that would go for other authors. It's also really interesting, because usually when you write a fic, the goal is to keep the core of the character and then do whatever you want with them. But then putting them right beside the Canon material, suddenly all the differences shine through in a way that I hadn't even noticed before.
For me, their first meeting is just a lot of staring and the my younger version gasps and goes "You're me!" Canon version answers with "Right" and then ignores my version for the rest of the day 😂
