I'm planning on evolving my eevee into an espeon for type coverage reasons, which means I need to take her to a move forgetter so she doesn't evolve into a sylveon due to the Alluring Voice that she knew when I got her from a breeder. That's her favorite move to use when we do battles (her other three registered moves are hyper voice, calm mind, and covet) so my brother says it would be so cruel to her that she won't evolve if I do that. I'd teach her the move again right away after she evolves, I just want her to have a chance to be an espeon because you can't get sun dust very easily outside of Orre and I'm absolutely not going to Orre. Do you think it would really make her that unhappy that she wouldn't evolve?
I was gonna delete this blog but I'm keeping it a bit more just to answer this question :3 Your brother seems to be assuming she really wants to be a Sylveon, you gotta figure that out with your Eevee and no one else, have her hang out with other Eeveelutions at the park, or maybe take her to one of those fancy Eevee breeding shows, see if she seems to vibe with any evolution in particular. You gotta pay attention to these signs (under cut cus I got a bit excited lol):
