Comments of chapter undefined of Shattered: A SAO Tale (Sword Art Online)

So I don’t know if anyone has made a connection but I really hope Yuki isn’t being replaced… I know it happens much later in the tower normally but I can’t remember if she started glitching before or after SAO launched. Though it also could just be a true AI like Cardinal in alfhim online. (Not sure if sleeping is right one that lol). I really hope it’s just a true AI.
