Oh my god, people, stop with the whole "Eeveelutions come in pairs" thing. It's annoying. There is NO reason for them to continue this so-called "pattern" because there isn't any significance to it whatsoever.
Vaporeon jolten and flareon, three is a pair?
Technically Gen 1 had two pairs.
Eevee/Flareon, Vaporeon/Jolteon... or however you wanna split them. Eevee did count as a new Eevee in Gen 1.
There is a difference between four and two pairs. --- Harmony is peace. Peace is unity. Unity is harmony. I tell this to the King Nook. He ask me to leave.
