I just found a hidden global Jhin quote

Edit: just a bug.

I'm pretty sure I just found a hidden quote from in my last game and I wasn't even playing him.

It must've been 30 minutes in, we were losing against an enemy and I just finished my wolf camp as when suddenly someone said

"It's fun to kill a man, to take everything he ever had. :^)"

Aatrox said one of his usual quotes right after that, which made me notice that "this isn't Aatrox who said that wtf"

He was right on the other side of the map too, but he literally whispered it into my ear and when I mentioned it to my friend I was playing with, he said he didn't hear it now or ever before that as a Jhin main.

I don't know if it's included in his vo and I'm not gonna sit through 20 minutes of Jhins fucked up lines to find it either. I think it would change me. Anyways.

Now this isn't something really noteworthy as we know that Jhin A. Enjoys the killing B. Hates the killing C. Wants to be caught D. Dislikes sandwiches

So why did rito put that in? Is this specific to Aatrox maybe?
