I'm so glad that Pokemon had made me learn Japanese all those years ago!!!!!

Everyone knows Shuu got an Absol. T_T
Saori was what Shuu is to Haruka: the rival who beat him on his first contest. In Shuu's first contest, he and Saori become friends/rivals, but Saori beat him in the final round...Like Haruka, he actually CRIED out of disappointment/regrets/whatever.
Oh my gosh.
After that, it seems like the two had kept contacting eact other throughout their journey. According to this Saori-neechan, it seems like recently HARUKA IS ALL SHUU IS TALKING ABOUT.
OH MY LATIAS!!
Dunno if this is come from Saori-neesama or not, but Shuu is come from La Rousse, i.e. THE CITY THAT WAS FEATURED IN THE 7TH MOVIE.
OH MY DEOXYS!!!!
Harley dressed as Haruka. And he comes from Slateport.
OH MY RAYQUAZA!!!! ((Faints))
Another note (which is relatively unconfirmed info because I only saw this from one site), this Saori person could possibly come from Pewter and Takeshi seems to know her (as in know that she exists, may not as friends).
