Nightmare found you while he was destroying an AU, you demostrated you could fight, so he took you in. But you're always a human, some monster's prey, and it seems one knows that you... Miss your mom.

After a fight, the others; Dust, Horror and Killer were already on their way to the castle, you were about to follow them but then you heard a familiar voice. A shadow-monster took the figure of your mother...

Nightmare noticed you weren't following them, as he turned around, his eyes widened up.
