Again, It's just my theory

With the release of the new Project skins, I came up with a theory. I might be wrong, But bare with me here. On the sneak peak of the new Project skins at the lol website, It showed new Project weapons used by a certain champion. Most of the people knew It was going to be zed, Lucian, leona, fiora. However, people were confused with Yi's weapon, and when people tried to get more info on the champion, It said memory lost. So people assumed this was going to be a new champion, possibly Yasuo's brother Yone (don't know if I spelled that correctly). When the skins did come out, It was Master YI. Now, in ingame, two of Master yI's quotes, (probably the two and only quotes), are "have I died?" and "memories, like shadows in the fog". So my theory is I THINK, Project Yi might be Yasuo's brother.
