Good ending is best ending, I'm happy for you Ditto. :)

Now let's hope a doting trainer will find both and give them even more happiness.

I wonder if the truth tag can be added since for some people it's like this too, as in other people like them only when the people in question are not really themselves, and when they try to be themselves people tend to shun them or dislike them.

It seems possible to me that Mimikyu could learn transform as one of its final moves. It wouldn't make Ditto irrelevant though due to Imposter.
