I know this is from the old lore, but whatever happened to the hinted crush/love between Garen and Katarina? It seemed rather entertaining, if some what cliche, for the two to have some sort of relationship beyond just enemies from opposing nations. Did the new story writers feel like it didn't work in the new lore?
There are several voicelines in-game hinting towards it.
It's still canon as far as I'm concerned.
Not that they are in a relationship, of course, but that they have feelings for each other.
It's still there just hasn't happened in present canon yet.
Go and see the special interactions videos for 
you'll see it's still canon it may be haven't happened yet but it will happen because these voice lines are from the new lore.
I dislike Kat x Garen with a passion. Don't like Garen at all as a champ or a character. Kat and Talon, Kat and Zed, Kat and Sylas, Kat and Kayn.
Whenever it comes up, Rioters leave the impression that it hasn't happened yet in the timeline but they will eventually meet.
Its still being hinted at. Just read some of the web comics rito has.
x 
look most interest more than 
x 
Its just that rito wants to hint at other things. I.E. possible alliances and nemesis.
I.E. ALL OF SWAIN

League of legends interactions are not canon but Legends of runetera has confirmed that all of it is canon and in there kata and garen have interactions that confirms they are a thing. Even garden's aunt knows about this and has a interaction with kata. I think I'm too late answering this but whatever.
