I think I'll go ahead and post my predictions for Iris and Cilan.
Iris
Axew
Emolga
Excadrill
Aggron
Zweilous
Axew: I can't see him evolving for a while.. if he does I don't see it happening until Iris's departure episode.
Excadrill: Done.
Emolga: Done.
Aggron: New Pokemon that Iris captures as an Aron. As an Aron it is rather lazy and docile but when it evolves into Lairon it becomes headstrong and stubborn and often picks fights with the other Pokemon. It would spend a decent amount of time.. in this stage and would eventually evolve into an Aggron in an episode where it gets separated from the group with Axew it would eventually evolve to protect him and retain its docile personality it had as an Aron.
Zweilous: I still have hope for this one as it still hasn't debuted yet and Iris has a Hydreigon in B2/W2 so maybe that boost her chances of getting this one a little bit. It would develop a rivalry with Axew after gaining Iris's attention as her "new" dragon type which would make Axew jealous.
