You can see the moment Ardiis mentally breaks in round 11 when he rips ult, Flys up twice and dies while not even remotely trying to take a kill with the knives lmao
they call Knight "K-night" probably because the Mandarin Chinese casters say "小K" which means "little K" instead of "knight" or a Mandarin phrase for knight
Saw somewhere the lore is that he wanted night ign but it was taken so he added a k, but still wants it to mean nighttime. And the pronoucation are as per the players themselves so no ambiguity there
