JANNA IS THE KILLAH

We all know the theory of how Riven is Yasuo's masters killer but I don't think that is the case because where in Yasuo's lore did it state that Singed was there? So there is no telling if the battle it said in Riven's lore is the same battle where Yasuo's master died.....But lemme get into what I think I think it was Janna Simply for the fact of she was a street vagrant surviving with her wit before she became the avatar of wind street vagrants wonder around so she may have wondered about to Ionia and she got offered a sum of money to kill him or something like that and the fact that she changed her physical appearance could be why they never found the killer and sounds mighty suspicious usually if someone changes like that its to hide something...... But hey its just my thoughts on it share you thoughts call me crazy,silly,(Maybe),ect. i'd like to hear yours!
