There is no episode in which it shows Gary evolving into his Eevee into an Umbreon, all that is known is that he had his Eevee as of the episode titled "The Rivalry Revival" however he ended up evolving his Eevee into an Umbreon prior to a Johto episode that was titled "The Power Play."
Blastoise Umbreon and Electivire.

I believe it's by losing to him once, but winning or avoiding the other times, out of the first 3 battles. Seriously just use google.
You go into garys room play with his animals
no you cant get umbreon since the only way to them is to evolve them at. night but you can get espeon by training him until your friendship is strong or at its best and trainig him. you can check how strong youre friendship is in the place where you start the game in garys house talk to his sister and she will tell you PS she only tells you if you've already beaten the Pokemon league
