This question is similar to another thread about how you think Arya and Dany should meet at the current point in the show/books. That question leads to this: If you could alter the story at any point, when would prefer Arya to meet Dany for the first time?
Personally, I think having Arya somehow end up in Meereen instead of Braavos after the end of 'A Storm of Swords' would be a good time period for starting any type of relationship between them. At that point, they've both gone through enough character building to be more established, personality-wise, but still have room to grow and change. It would also be interesting to see how Arya would potentially influence how Dany rules Meereen and what her impact on the events there would be.
I Stan so hard the idea of them meeting while Dany’s still trying to become the ruler she hopes she can be. So, basically anytime before she gets to Westeros.
