Just a question that came to my mind this morning. I've never been a huge fan of it (my ship is Shaco x Jinx) but I'm curious what people thinks she sees in him and vice versa.
EDIT: Glad the conversation went well, just curious why the down votes, is something wrong with this line of questioning?
Years into the future:
I may not be as young as I once was, but I can still hear an assassin creeping into my room.
As sharp as always, Garen.
I thought you were retired. Your body aged so that you couldn't serve your country.
Are you calling me an old maid?
Heh. The wrinkles on your face do not detract from your beauty, even after all these years.
Your grey hair gives away your age, can you still survive a fight?
Is that what you're after here?
...No. I came to give you something. Something I could never give you while we both served.
Your skin is still soft.
Yours is still rough.
Shall we retire for the night?
I'm afraid not. This is for Noxus, you understand.
Ah, the hidden dagger. I fear that you've caught me off guard.
A mortal wound.
A mortal wound indeed.
Do you despise me now?
No. I admire your conviction. I've always admired that.
Shhh. Lay back. I'll steal your last breath from your lips myself.
An honor to perish in such a manner, mylady.
Now I'm just blushing. Be still, my l-
It would seem we're both alike, Katarina. This is for Demacia, you understand.
I feel so foolish. I never would have imagined you using a hidden weapon against me.
I may have become more wise with age.
Hah! Your skull is still thick. But you have good aim.
A mortal wound.
A mortal wound indeed.
Shall we rest together?
It seems I have no choice. Although. It could be worse.
We go together. I would have it no other way.
Look. Our blood is mixing on the bedsheets. What a... beautiful...color...
Sleep now...
Garen. I'm here to summon you. Jarvan wishes you to meet him and J5 for a rousing game of Kill the Teemo.
Garen?
By the king! They're dead!
...Would that love known any other form, they would have been happy together.
No. Perhaps they were happy together. In their own way.
Also worth noting Garen defended Katarina from his own soldiers when she went to Demacia with information on the Kalamada scandal.
Katarina likes Garen for his determination, character and loyalty for not only his city, but also for his own beliefs.
Plus, he is hot as fuck.
Well, Garen does lift the world up when he does handstands, isn't that enough? Plus he has the sexiest dance in all of League
A REALLY 
?
He's like her. Loyalty is all that matters to him. He fights hard and he fights only for his country - not for personal gain, not to further any hare-brained schemes of his own. She probably sees him as one of the rare few who actually understands duty as a fighter should.
Katarina with Garen be like
Garen admires her beauty, devotion and fighting ability. She literally will do anything for noxus because that is how loyal she is to it. ''Never question my loyalty. You will never know what I endure for it.'' -- Katarina It also says this within garens lore "Even simply the pursuit of a worthy opponent on the battlefield is, to a true warrior, the reason to rise each morning. The promise of one, particularly so beautifully and diametrically opposed, is the validation of his existence."
Now i don't know what katarina sees in garen. Maybe she admires his loyalty and strength as well since last i checked garen is like on of demacias finest soldiers but in the end i do not know. I personally don't want to see kat with garen but that is just cause i don't like garen. I'm not sure who id rather it be but in the end it is what it is. Kat will always be my Bae.
He's a 7 ft tall muscle bound soldier/national hero. Does that explain it?
Katarina likes the big sword, just like how Nami likes the little boys. Katarina likes the big sword, just like how Riven likes shapeshifting green blobs. Katarina likes the big sword, just like how Vi likes other officers of the law. Katarina likes the big sword, just like how Elise likes insects. Katarina likes the big sword, just like how Rumble likes purple skinned, white haired, rocket jumping, yordles. Katarina likes the big sword, just like how Soraka secretly likes lycanthropes. Katarina likes the big sword, just like how Ezreal wants to see the light, but Taric wants to show him the family gems. Katarina likes the big sword, just like how Lulu wants to be special friends with a certain demon jester when she is no longer a minor. Katarina likes the big sword, just like how Orianna only likes the large machines. Katarina likes the big sword, just like how Garen likes her personality. :)
She sees a kindred spirit. Garen lives the life Katarina does, and in some sense they both can tell that they are sick of it. They have really high expectations for set for them. In the heat of battle they don't have any room for error or else moral will take a huge dive. A lot of weight they have to carry (n00b team sigh).
They're also equals in battle, something Katarina has never come across. In my headcanon they're the strongest fighters in Runeterra, battle-wise. After so many battles against one another there is an understanding, even a "relationship" that they hold. They probably always think of new ways to corner the other, try and triumph, but this sort of challenge is something they fear is once in a lifetime. Once they are victorious, there will be no other quite like their old rival.
Also, there is the irony that in two completely different societies, under two completely different ideologies, they are just a reflection of one another. Thats something fantastic and profound to Katarina, and to Garen. They aren't fools who just swallow the propaganda of their respective nations, mostly because of their rivalry which changed how they think. They want to know more about the other because through their clashes they have recognized how similar, how close they really are. The only one who truly can relate to their personal struggles and thoughts. Someone to be honest to, someone who would understand. Garen wants this as much as Katarina wants this.They just want to talk, in a moment of peace and quiet, and see how deep their similarities are. But reality is harsh, and all they can really do is speak with their weapons.
(Hint: They perfect matcharino)
But its not just Romeo and Juliet.
She likes them big and dumb.
Not a fan of the couple, but if people want it, people have it.
Not sure why, but it clicks. Kat probably admires Garen's seriousness and fighting ability.
