Talk:One-Eyed King/@comment-10733658-20150922051824/@comment-26689808-20150922143146

I don't think that Nico told Kaneki directly that the One Eyed King was Eto, but he may have figured it out himself.

I'm pretty sure Nico told Kaneki that the One Eyed King was the One Eyed Owl. After this, Kaneki was starting to have suspicions on Aogiri Tree, namely Tatara, Noro and Eto.

Then when Kaneki visited Yomo, he found out that Yoshimura was covering for the real One Eyed Owl, which then led him to confront Yoshimura himself.

The first thing he asks is this: "Is Aogiri Tree's Leader... the One Eyed King... no, the One Eyed Owl... your child, Yoshimura-san?"

Kaneki may very well have discovered that Eto is the one he's looking for, through process of elimination (since she's always with Tatara and Noro who are described as subordinates).
