Say I get two eevees through the GTS, from japan. They're not nicknamed, so the names are just whateverthehell the japanese name for eevee is. I then trade them to a friend (they lack a ditto and their eevee is male). The friend evolves them. What happens to their names? Does it stay the japanese eevee? Does it become the japanese for whatever form it evolved into? Does it become the english for whatever form it evolved into?
