Joe Ga didn't really take the "rescue the princess" thing seriously...
Because he felt that it was only after the princess had gone to Central Africa that P·B would feel the direct pressure.
After all, Princess Amina wasn't actually in prison. How much trouble could it be to sneak her past a few servants' surveillance?
He let Nis and her group of girls ponder blindly how to crash the Crown Prince's party and steal the princess away, just like in the movies.
Joe Ga found his way to the study alone, then picked up the phone and called Karman, who had been busy in Central Africa on his behalf, to learn about the detailed situation at the base and then told Karman his return date.
Joe Ga hadn't been in America for very long, but he could quite clearly sense the 'uncertainty' in Karman's tone.
The old guy feared that the boss would fall in love with prosperous America and eventually shift the focus of the business to the United States.
