Though I don't know which is which my guess would be that Dawn is the one on the right. Isn't it Dawn that will be doing the princess role? Iris I think is the one on the left as her clothing doesn't look as royal and elegant as the one on the right. PK can scold me if I'm wrong.
The only hint that I saw visually in the double episode was when Dawn and Ash were training together alone. Thank god Brock finally wasn't with them for once. There may have been spoken hints but I don't know a scrap of Japanese so I'll leave it to PK to point them out as he knows better than me.
I don't really know what to think regarding the two upcoming episodes. the episodes themselves look Pearlshippy but I can't say the same for the writer. I'm gonna let fate decide this one but I'll be prepared for either possibility.
