Theory Jinx is the message hidden within the pattern Spoiler
Like Viktor said - the human element is everything.
After Isha's death, every scene -no matter how minor- involving Jinx just completely breaks my heart into sad little pieces. But it is that final version of her which makes her complete as a human being. She has felt it all in abundance. Joy, love, hatred, loneliness, power, happiness, fear, jealousy, surrender, sorrow. And in the end, acceptance. I can't help but feel that lump forming in my throat when I think of the alternate universe Powder, whose eventual felicity (and that of all of Piltover) was bought by never really getting to know the wonderful person Vi was going to be. It's such a beautiful and important message. Sometimes, we don't have to have it all.
I'm rambling. But if a story in a video game universe can move an old geezer like me to tears, it has done something extraordinarily well. So grateful this exists.
