"I am not a human, I am an animal. A cold-blooded animal."

"You poor, unfortunate fool."

"Life's a bitch, isn't it?"

"I've been dead once already. It's not so bad."

"Face your fears with courage."

"You can't live your life in fear."

"Snakes. Why'd it have to be snakes?"

"Fear is just another obstacle to overcome."
