* The end credits:
---> Duelists, thank you for a decade of dueling... and the best is yet to come!
* When Jaden and Yusei save DMG from getting blasted using De-Fusion and Junk Gardna's ability, she has a cute grateful smile.
* The fact that the protagonists work like they've been Tag Dueling together for years, even though they have no clue of each other's play style.
** That said, Yusei and Jaden could have a good idea of what Yugi's play style is, Yugi being the very first King of Games and all, Jaden specially, since he even dueled against Yugi before.
* Yusei tells Yugi that if it's necessary to [[ShootTheDog destroy Stardust Dragon]] to stop Paradox, to do so. Yugi instead resolves to get it back, and does!
* A blink and you'll miss it moment when Paradox plays Rainbow Dragon. Judai is absolutely ''furious'' at him for ''daring'' to use Johan's card. A callback to the beautiful "J and J" friendship.
