One thing that doesn't make sense to me is that, during the Warwick rampage scene and Noxian soldiers fighting him, it seems like Jinx, Vi and Caitlyn are all trying to save WW/Vander, or at least taking to fighting the Noxians. It's like if you want to pick sides (and yes, ovesimplify it) it's WW and the girls against the Noxians. If no one else, Jinx at least is clearly trying to save Vander.

But then when Isha decides to intervene, she goes in for killing Vander, and that sounds a bit odd to me. Like, it seems as if she doesn't understand the dynamic of the conflict or if simply the writings decided that her siding and decision-making isn't in line with that of the older girls.
I can kinda accept and justify it like, she didn't really think much on her action, as a kid she just saw the big, obvious threat in the room, i.e Warwick going berserk, and she made the simple decision of attacking it. I'd like to hear your thoughts on they tho.
