"I was born on a battlefield. Raised on a battlefield. Gunfire, sirens and screams... They were my lullabies..."
"I finally understand. I wasn't waiting to kill people... I was waiting for someone to kill me. A man like you... You're a hero. Please... Set me free."
Basically, a crazy predator girl that watched her family and friends die over time...her worldviews becoming twisted as time went on.
She thought she was finally free when Snake killed her...but she couldn't have been further from the truth...she has a huntsman curse. She seems to...come back if she's killed, so long as her soul isn't taken.
She's changed a bit though, she's a bit more personable now...
