I'm confused. What happened with the whole thing with Yugo and Yuto? I never got to that part yet, so I am super confused about this whole thing.
Okay, well, this IS a spoiler, so don’t read if you don’t want to bespoiled.
Basically, it started off with Sora challenging Yuto, demanding toknow where Shun was so they could have a rematch. Yuya followed froma distance and ended up joining Sora against Yuto in an attempt toprotect Sora. Sora is dragged back to the Fusion Dimension in themiddle of the duel, and then Yugo shows up. Yuto and Yugo hadalready met before and both thought the other was allied with Fusion,and so they started dueling.
Both of them get out their ace dragons, Dark Rebellion XYZ Dragon andClear Wing Synchro Dragon, who start to resonate with each otherstrangely. Both boys’ eyes start glowing and they are suddenlyconsumed with a need to destroy. Yuya, who remembered hearing Yutosay he didn’t want to hurt people anymore, tried to snap Yuto out ofit. He managed to get through to Yuto, who snapped out of his“dragon rage”, but Yuya was not quick enough or close enough toYugo to snap him out of it too, and Yugo attacks with Clear Wing,defeating Yuto.
After that, there’s a weird scene about smiling (EGAOOOOO)(which we will see in a million and one flashbacks like wow I thinkwe remember that happened writers) in which Yuto asks Yuya to try andbring back everyone’s smiles, gives Yuya Dark Rebellion Dragon, anddisappears. Yugo then snaps out of his dragon rage and is like ‘thefuk just happened’ and then I believe he’s teleported away when Yuzuappears to find Yuya.
To add to this, only Yuto thinks Yugo’s allied with Fusion (thanks to his name, as the dork is forced to correct others on the pronounciation lol); Yugo just thinks Yuto’s behind whoever took Rin (”someone I love”) from him. Later, we find out it was Yuri who took Rin, and so Yugo’s teleported to Heartland, where he meets Yuto, except he mistakes his face for being Yuri’s while Yuto mistakes him for being with Academia (given the destruction going on, it’s natural that it’d be his first guess), and so they clash. All while Yuri watches nearby.
And then comes that duel where we get EGAO AD INFINITUM.
So, this all started with a misunderstanding.
FUNNY, RIGHT?
