Okay, now that they are confirmed fake, might I suggest thinking about the following two things:
1) In Dento's gym, you seem to choose the type that is SE against the one that is on the curtains. You saw grass/fire/water symbol on the ground and fire symbol on the curtains, so you picked water. Also more importantly, after you defeat Dento, you'll notice 2 people standing behind him. Dento (green hair), a red-haired guy and a blue-haired guy. Red/blue/green... Fire/water/grass... Three coloured gems in the badge, also red/blue/green. It seems either your starter choice determines who you'll fight or which symbol you'll choose in the end. (Or maybe you even have to defeat all three of them?)
2) As we all know I think, we can see 4 badge silhouettes. Dento's, Aloe's and then we see a wing/heart one and a thunderbolt one. Which type would the wing/heart be?
