I feel like Bastien would have a Zorua as a companion Pokemon and they’re adorable and the best of friends, and Zorua is the one who makes the illusion that Bastien’s father is still alive because the idea of Bastien knowing the truth and being so upset and depressed tears Zorua apart and being the illusion Pokemon, he just won’t let that happen.

So Zorua carries the burden of knowing the truth and keeping it from his best friend and trainer.
