She blinked and stared at him for a while after he was done. 

God has his plans. He has his reasons. He works in mysterious ways...

These sort of things ran through her head as she looked upon the young man who proclaimed to have died, though she knew he was talking about his soul and humanity. 
A vampire who has maintained her humanity, and a human who thinks he's long lost it. It was too perfect to be a coincidence, she told herself. Just when she began to feel like a little girl again, trying to please her silent father, this boy -who was supposed to be her enemy- has come to her with the answer. 

Suddenly, after all of the solumn speeches, the dark air around them was broken by her gentle laughter. 

"I will come with you."

She got up and went to wrap her arms around him. " I will not falter..."

Yes, she was sure this would confuse him. But God has brought to her a source of inspiration, a reason to keep her chin up, just as she was faltering in her beliefs. She was sure that if she was faltering as much as she had been lately, that she wouldn't be able to keep being good...that she would start not caring about anything anymore. So, even though they had only known each other for a short period of time, she decided that she would make a pact with this man. He was going on a journey to find something that could grant her greatest wish. She would help him, and be repayed by the use of the medallion. In the meantime, she thought, she would need to open the boy's eyes, like he had for her.
