Yall, i dnt know who needs to hear this but i have a theory...
we know Cyn gave V, N, and J a mission and in the last episode i think it basically confirmed their mission was to kill Yeva and Nori (and since Uzi and Doll were born them as well) so N didnt kill nori just on a whim, he was hired to kill her spesifically because she had the solver as was V with Yeva. its really obvious looking at it now i just thought it was neat lol. but hey, thats just a THEORY
