Jhin says to katarina "your finale will be a duet"

Edit: jhin and Katarina both have close to the same exact Q spell. It could mean that jhin is very interested in having Katarina as a partner.

duet = 2 . Cass has no interactions with jhin nor does jhin mention a duet to anyone else.

When jhin uses the word "finale" he's always directing it towards himself. When he is referring to other people, he uses words like art, masterpieces, works, etc. but to katarina he uses the word "finale" which he only uses other times to describe himself. That's why I think it's 2 people(kat and ???) killing others and not jhin killing 2 people.

when I think of Katerina and finale in the same sentence, the first thing that pops in my head is a badass penta kill. I'm going to go out on a limb here and say that there will be a new champ with a crazy penta kill potential like katarina.
