"Alice…"

In the cold silence of the obsidian castle's throne room, one voice spoke the girl's name. However it wasn't Sam's. 

Hela, the Nephilim queen, walked in slow steps, her bare feet making a distinct sound each time they made contact with the spotless floor. The terrifying aura she always emitted was gone making her appear like a different person. The red halo above her head slowed down and the symbols making it became visible, each one flickering as if they were about to disappear.

Seeing a blue hand touch the glass container shook Sam out of his stupor like state. He still couldn't believe what was in front of him, the contents of his stomach rising up to his throat. He fought the urge to vomit and turned to look at the other Alice, the one who's been with him through the past twenty years.
