Why does Eren need to touch?
Why does Eren need to touch? It’s simple — he is not of royal blood. In order to truly access the Founding Titan’s abilities, the holder needs to be in physical contact with someone of royal blood. This is why Zeke Yeager is needed.
Why did Zeke and Eren wait to touch?
It was a trust exercise between half-blood siblings. Or Eren decided to follow what he saw would happen in the future, meaning he had to wait until it was the right to act, not then or later.
Who knew of Eren’s plan?
As it turned out, Floch not only knew about Eren’s attack ahead of time, but he also knew about Eren’s plan to betray Zeke and his Euthanasia Plan to instead use the Rumbling to destroy the world, 10 months before it actually happened.
