Pokémon X and Pokémon Y

i don't get the one about the spider. If he has the game he could easily go back and confirm its name..

Same with Froakie's evolution. If he is using it, why can't he confirm it's name?

He also somehow knows Raichu and Tropius's mega evolutions but makes no mention of Mega Stones whatsoever? and I thought you couldn't get Mega Evolutions until you go to the mega tower?

If he is legit, he's definitely picking and choosing random things to reveal and completely skipping other things (like new pokemon, gym leaders, plot)

And how did he "only" see the pokedex entry of the mirror pokemon, as well as the fact it has an evo, yet not know the evo's name?

EDIT: He's still updating the site. He's mentioned Mega Stones now. You get them in a similar way to mining from the 4th gen. which, if true, is kinda what I expected.
