Deal Game, Test of Wit More of the Kingdom of Senku begins reviving the rest of the crew just as Amaryllis arrives with news of Kohaku and Ginro's petrification and that Soyuz is likely the Master's son.

Moz appears in the cave at that moment, but in a moment of extremely rapid deduction, everyone realizes Moz knew Kohaku and Ginro were intruders yet never told Ibara, meaning Moz is secretly Ibara's enemy...
