Ogeode turns Moltar into crystal after the series finale
After Moltar's Heel–Face Turn in the last issue, Zardeth punishes him by turing him back into a human, which means he and Lavour will never be able to touch each other again. But there's an obvious solution, since Ogeode could turn him into crystal like his brother, if both he and Moltar are willing.
