You never really know how low someone can go until you see it first hand. Evil is too kind a word to describe Gregory.

Twilight struggled to stay awake as she copied down a layout map of Gregory House from memory. Occasionally she would nod off and Nekozombie, not hearing her work, would call to wake her up. Twilight smiled, glad she had at least one friend with her.
Then, after an amount of hours unknown to Twilight, she finished her map and went to sleep. "Goodnight Nekozombie," Twilight called, "Just a few more days, er nights rather, and we can get out of here." "Goodnight Twilight." Nekozombie yawned, clearly skeptical of his own chances of escape.

Twilight didn't know if it was the squeaking of the floorboards of the clanking of the vault door of Nekozombie's room, but something woke her up. She was groggy and confused, so she stayed in her bed and listened to what was happening in the next room.
"Wakey! Wakey!" Gregory shouted. His shout was followed by a sound that Twilight could only guess was a kick to Nekozombie. Suddenly aware of the fact that her friend was in danger, Twilight started to get out of bed.
"What are you three doing here?" Nekozombie questioned. "Well, I couldn't help but notice that you haven't payed your rent in quite a few years. This is a very serious offense with very serious repercussions. Me, Chef, and Katherine are here to enforce the law."
Twilight froze at the mention of Katherine and Hell's Chef. If it were one, or maybe even two of them alone, then Twilight could handle it. But all three of them, Twilight couldn't even imagine surviving that kind of confrontation. She wanted to do anything, to help Nekozombie, but she was paralyzed by the horrifying prospect of being trapped in a room with the blood thirsty nurse, the deranged chef, and worst of all, Gregory.
What followed was over four hours filled with the sounds of fists beating, knives cutting, needles stabbing, grunts of effort, and Nekozombie's whimpering.
Twilight tried to force herself out of her room, to go to Nekozombie's aid, but in all that time, in all her fear, she only made it to her door.

Finally, the sounds of torture ended and Nekozombie's door closed. When she was certain all three of them had left, Twilight ran and looked through the keyhole.
Nekozombie lay on the stone floor, beaten, battered, bloodied, and defeated. "Nekozombie?" Twilight called, praying she would get an answer. "I'm... still... a-alive Twilight." Nekozombie said in pained breaths.
Twilight let out a sigh of relief, "How bad is it?" She asked. "It's not the worst they've ever done, but I don't think I'll be moving for awhile." Nekozombie said. "You'll be okay enough to escape when the time comes right?"
Nekozombie sighed, "Twilight, if I'm walking a month from now, it'll be a miracle. I'm sorry, but the only way your escaping alone, if you escape at all."
Twilight wanted to tell him that he was wrong. That he'd be okay and they'd escape together. But she knew how weak Nekozombie had always been, and after this, he didn't have any spirit left to fight with.
Twilight, eyes watering, stormed down the hall. Her emotions were all but bursting from her mind; sorrow, fear, guilt, worry, and strongest of all, anger. She was angry at all of Gregory house, and come hell or high water, she was determined to get out.
