We have been teased by the journals and reds since 2012.
Now with the release of 
and his taunt to 
stating: "The always-enchanting tale of star-crossed lovers."
and to 
: "Your finale will be a duet." (Duet with Garen, I assume)
Rito pls! Either make this canon or give us more of teasers like this.
It already pretty much is
it is canon but still does it change anything? no look tryndamere and ashe are married but no difference in gameplay or even in the lore, same with lux being garen's sister its the same even if they were not
Yeah ain Cannon ..yet.
At Riots pace it never will be. Besides honestly it's way to cliche and there is NO reason for Kat to "love" Garen.
