Only now i realised they refer to the Abyss version of Alice as Alyss
Good one lol
So it all started coz
The core of the abyss got lonely > found the twin child of Lacie's (still can't forgive that previous glen and his f*cked up experiments) > possesses Alyss and became will of the Abyss > will of the abyss is weak and can't really contain the power of the Abyss, is mentally weak so it was easily manipulated by Jack to give him BRabbit chain > what happend happens
