Well, I'm not sure if you're talking seriously about the S=R-Theory or just kidding around, but it's crap. I may be wrong, but as far as I know, There shouldn't be a "Selphie" in the game. Rinoa was later replaced by Selphie. You can see a lot of Screenshots of the Trial-Version, where Rinoa is standing at the beach of the Dollet-Mission or something like that. But in the full version of Final Fantasy VIII, it's Selphies' part.
