As soon as Stiles heard his sister scream, he was running. He ran throughout the corridors of Eichen House, screaming his sister's name, but no one replied. And when her screams stopped, he became even more panicked and increased his speed.

Finally he rounded the last corridor, his eyes horrified at the sight they saw. His sister lay in the corner of the room unconscious, her body covered in blood.

"Layla." He roared and banged his hands on the glass door. He needed to get in there. He needed to scoop her into his arms and carry her out of this hellhole. He needed to hold her and never let her go.

Theo didn't even know she was here. He didn't know what had been done to Layla or what had been happening to her, then again no one did. They didn't realise there was something wrong until it was too late.

And now they couldn't save her.

Relief filled Stiles as his twins eyes flickered open but his stomach dropped as he saw their colour.

Pitch black.

Her eyes were like an abyss, two black holes that were both hypnotic and terrifying. The blood ran back up her arms and legs as the wounds healed themselves. Grinning, she stood and rolled her neck, cracking it as her eyes faded to their normal colour.

"Oh that is better." She laughed.

"Layla?" Stiles whimpered.

"New and improved." She laughed and walked forward, pressing her hand to the glass. It shattered under her palm and fell to the floor like snowflakes.

Stiles stumbled backwards and Layla actually looked hurt. "We won't hurt you Stiles."

"We?" Stiles echoed.

"Yes." Layla confirmed. "We are one now."

"Who Layla?"

"The Goddess and I."

Stiles felt sick and he knew that Theo's words hadn't been a lie. Layla had been possessed by the Chimera Goddess, they were bound and his sister had done so willingly.

"We know what we must do and why we are here. We will not hurt you." Layla promised and turned to leave when Stiles grabbed her arm.

"Layla, whatever the doctors have done to you we can fix it. Just please don't leave, not again." He pleaded.

Layla's facial expression softened and she placed her hand on Stiles' cheek. Whatever she was at the moment, Stiles knew that she would not hurt him just as she had said.

"You can't fix me Stiles." She said and Stiles knew that it was just Layla speaking. "I've said yes, I've made my choice. And there's no going back. You can't save me and please don't try to, you could get hurt. Save her for me, save my Lydia. I love you Stiles, goodbye."

Her eyes went blank and she straightened. "We must go." And just like that his sister was gone again.

And so he had to watch helplessly as his sister walked away from him again.

Layla watched as her brother drove away with Scott and Lydia. He had saved her, her best friend was safe.

"You can let go now." The voice said, knowing she hadn't completely succumbed. But they had something to do and they had to be one to do that.

Layla closed her eyes, a tear running down her cheek.

"I can let go now."

And she did just that.
