TBHK 111 SPOILERS BELOW CUT
GUYS THEY DIDN'T JUST GO BACK TO BEFORE THE FAR SHORE ARC HAPPENED. THEY WENT BACK TO 1968 WHEN THE TWINS WERE ALIVE WTF
Also, I KNEW IT. Yugi Tsukasa died in 1956 at four years old. TBHK just got real dark because damn. That entity has been using Tsukasa's body as a puppet this whole time, AND AMANE KNEW SOMETHING WAS WRONG THE SECOND HE LOOKED AT HIM OMG
It was implied ever since the red house arc that the Tsukasa we meet in that house is not Tsukasa, it's just his body. The last time the real "Yugi Tsukasa" talked to Amane, he told him "of course I love you!", and then, without having talked to him after that, red house arc Tsukasa says that Amane hates him? Yeah he's a fake
This was also implied with the God telling Sakura that the wish she made hundreds of years ago would come true soon. HOW does Tsukasa know that? The twins have existed for maybe 50+ years, so this means that Sakura doesn't work for Tsukasa, but the God living inside of him. She could be his worshipper, a kannagi sacrificed to him, or sacrificed someone to him to get her wish granted (or all of those options)
Because of the clock keepers arc, we know that everyone will remember everything (except Kou, because he hasn't been frozen in time, and Aoi for some reason). Hanako remembered because he's a supernatural, and a high ranking one at that, and Nene would have remembered if it weren't for Mirai trying to move her time forward. Nene remembers at least, she wouldn't be making a face that screamed "I was five years old and in court two seconds ago, what happened."
There are so many things that could happen like... If Teru DID hear what Akane said, he might find Nene first which we don't want yet since we don't know what Akane asked of him. Now, since Hanako always keeps his memory of a jump back in time, it's possible he's alive as Amane right now and has his memories as Hanako. If we're lucky, he'll find Nene first. GUYS THOSE TWO BEING IN 1968 IS SUCH A BLESSING IN DISGUISE. AMANENE COULD BE CANON IF THIS TIMELINE BECOMES THE NEW PRESENT
