A New MAVO Member - S1.E10

Jack takes the five Crystals (four real, one fake) to MAVO HQ and gives

them to Quellor. A celebration is held in honor of the find, and the Understander of Legends installs them in the MAVO ceiling. The Trio shrink themselves and the Airship and infiltrate MAVO HQ, and quietly replace the real Crystals with fakes, starting a brawl along the way. The Airship slips away during the commotion.
