Stitch & Ai S01E06 - The Lock

Ai explains in the cold open that Stitch was protected by "special qi energy" during his re-entry into Earth's atmosphere in the first episode; the same energy was also responsible for him losing much of his memories of his life before Ai, including Lilo. He knew that he had to find a secret shrine but does not know where it was or why he had to find it. In the episode proper, Ai takes Stitch to a bridge where several locks are. Friends write their names on the locks and lock them on the bridge as a symbol of their unbreakable friendship. Unfortunately, Stitch does not agree with where to place the lock, resulting in them fighting over it and dropping the lock below the bridge. They then get attacked by both Woolagongs and Jaboodies going after Stitch once again, and Pleakley ends up getting caught up in the fight when he tries to rescue the duo. Jumba sends out his latest experiment, a xiezhi, to save Stitch, Ai, and Pleakley. After the two alien factions are defeated again, Stitch finds the lock, and he and Ai finally agree on a spot to lock it.
