Cole, Jay, and Kai blame Zane for the loss of their home, and in the ruckus, no one notices Zane flying off on his dragon.

Trivia

 * Many of the series' main events were commenced by the events of the first season.
 * The Great Devourer's death in season one caused the Stone Army to awaken in Season 2, which also led to The Overlord's final battle with Lloyd.
 * The Overlord's defeat left him vanquished and vengeful, and in the third season, he fought the Ninja. Zane seemingly died when he destroyed the Golden Master.
 * After the loss of Zane, in season four the Ninja went to find him on a mysterious island. They faced Master Chen's army, which was banished to the Cursed Realm through Garmadon's sacrifice - however, this allowed Morro to escape.
 * Morro possessed Lloyd in season five, and went on a quest to unleash The Preeminent, the physical manifestation of the Cursed Realm. Nya drowned The Preeminent, destroying the realm and killing its prisoners (including Garmadon).
 * Djinjago, the sister realm of the Cursed Realm, collapses due to the latter's destruction. Nadakhan seeks vengeance against the Ninja, and though he succeeds, Jay wishes that these events never happened.
 * The events of season seven didn't directly correlate to the previous seasons' events - rather, they were in response to events from long before the pilot episodes.
 * Harumi, who was orphaned after The Great Devourer's rampage in season one, seeks to resurrect Lord Garmadon, who died in season five. This goal is ultimately fulfilled, and the original Ninja and Wu wind up in the First Realm.
 * The Ninja try to escape the First Realm in season nine, while Wu ages back to his normal self after season seven's events. The Resistance holds up against Lord Garmadon's rule. Garmadon is defeated, but warns of a coming darkness.
