No, no. I understand perfectly. If this Azula went away, my Ty Lee would be seriously screwed. More so if they decided to take her past a certain point in canon which the DDD versions won't/can't go through due to the build up being wrong. Or the same if I dropped Ty Lee. It hasn't happened nor is it likely at this moment in time yet but it possibly could. Mai, aside from some built up agression, is basically the same character with the same canon boyfriend so someone could pull her off easily enough.

They got used to it eventually, but it was a bit slow going. (As the first Azula would have asked for Ty Lee to return but not Mai. The new Azula asked for both, which Ty Lee brought up but didn't question it when Azula said "Mai? Why shouldn't I?". Part of that was due to Ty Lee's temprament of the loyal subserviant friend to Azula, though.)

As it is, if the new Phoenix-mun agreed, another dimension would be the best bet.

And personally, I don't think it's being too selfish. Just...thinking ahead. Because if you enjoy playing here and if you can figure out a way to play without Idgie's Phoenix, then you shouldn't have to leave. Obviously you can still say something about Edgeworth's relationship with Phoenix still going on, just from Edgeworth's POV. I'm guessing it would be in private entries, but still. It could work.

....and now I'm rambling.
