I may have an idea on what will happen in the finale of the Beykingdom Arc…
So we know what the objectives are specifically for X and Dima:
X’s origins are tied to the Beykingdom and Dima’s goal is to become the next monarch.
For X, we could see his side of the family actually being as strong as him and when the finale happens, he finds out about his parents/relatives whereabouts in the Beykingdom which warrants him to not join in the final battle.
For Dima, he will take X’s place and it will be him, Bird, and Multi against the antagonist team.
In terms of a narrative sense, it makes sense because they already set up what they are going to do with X and Dima and if X was in the final battle instead and Dima ending up becoming a traitor to Team Persona, then we would have a problem. If Dima was plotting with the King or the evil princes, he wouldn’t go through the trouble of asking a high-ranking civil servant like Kiwami from the outside to be on his side. As for X, I feel that finding his real family should be a major plot point and not something to gloss over, considering that we still don’t know about X when we know more about Bird and Multi’s origins.
