Okay look, if we're seriously going to address the question of how he became king, we have to know whether Bosh ever actually had kingship transferred to him (shouldn't be too hard) and if John retained all his rights and perhaps even his position afterwards. If John was still king or still had his rights then it seems likely that John gave the kingdom to Packratia (maybe for USD, maybe not). If Bosh was the sole king then it's more likely that the staff did it, but it would still be possible that Bosh made him king (maybe for USD, maybe not).
