I watched a random cutscene on youtube where he fought creepy Johan/Jesse and his heart stop beating then vanish into pixalette. It really makes no sense. So yeah I was really wondering since everyone there said he's dead and Syrus crying like there's no tomorrow.
In fact this was the saddest moment in the anime(In the Japanese version) yes this is zane dead..i was thinking after that the anime will be so boring but I continued watching and see that Chazz and Alexis
are appear(they was died to)and tell Jaden that
they all were not dead just send to another world and he have to defeat yubel for return them to the life..the same thing happened to Zane
Apparently, they all came back to life afterwards. I just saw the episode where Edo "died", but then I know that he was still in it. But was Ryo's "death" different? I can't remember if it took them longer to find out that he was still alive.
