We reach the conclusion of our second story arc, and see our first real Ultimate level member of the team in episode 20 - "The Earthquake of Metalgreymon" or "Evolution to Perfect! Metalgreymon"

Along the way: Needlessly enormous hidden rooms, Datamon is ruthless about possibly sentient life, a plan that works entirely too well, Etemon breaks the already stretched rules of the Digital World, Joel and Jules cannot stop saying the p-word, and we try matching Digidestined to the various regenerations of The Doctor.
