That Johnny line has to be a mistranslation of sorts. Cloud failed to get in to SOILDER. And if he failed to get in then there is no way that loser Johnny would make it.

That guy's a jerk. I kept thinking he was trying to steal Tifa away from Cloud. I think they should have had him keep popping up throughout the game though. Maybe he shows up at The Gold Saucer and then at Icicle Inn etc but it seems like they forgot about him after Costa Del Sol.
