Caster blinked, momentarily floored by her Master's words and actions. She had prepared herself for the sort of Master way in over his head and requiring her gentle guidance in order to survive this iteration of the Grail War. Yet here was her Master, having demonstrated his mastery of the mental arts on the peasants, established a secluded love nest for their activities, and proved he possessed strong moral convictions to boot. 

"I'm truly the luckiest Servant to ever be summoned if I have a Master like you." Letting the spell tag fade into the ambient prana, Tamamo accepted the offer hand and sat sieza beside her Master's sleeping bag. She was practically glowing with joy as she smiled at him. "You already know my name and legend, there is little more for me to add at this time. Our fate's are intertwined, so you shall have my utmost trust Wes."

The rule about not killing civilians might be an issue in the future. Not that she had any great compulsion to go out and eat their souls, blood, or semen but if it came between pushing an old lady out of the way of a speeding car or keeping her Master safe, she knew what she would do. The insinuation that she was the weakest Servant class stung even knowing she had E rank STR and END, but it wasn't hard for her to justify it as Wes showing concern for her safety. Such a kind Master she had. He likely couldn't imagine life without her now.

"So you are seen as a heretic. Does that perhaps have to do with your wish for the Grail? My wish has already been granted, so I can dedicate myself to bringing about yours!" 

A sly grin pulled at her lips as she turned away to leave Wes staring at the top of head and the attentive fox ears. "But if I am to be the best wife I can be, I expect you to work just as hard. I can't reveal my secret garden without you reaching sufficient relationship flags!"

The thought processes of divinity is truly beyond all mortal comprehension.
