Caster was outwardly silent as she entered the taxi and rode with the magus to the liquor store. The ride was short and quiet until they arrived at a quaint little liquor store and exited the vehicle. She would accept the offered money from Seyrun and purchase a good bottle of sake before joining Seryun out front.

"I must thank you for your assistance this day, honored Magus. It would reflect poorly upon my wifely skills if I had failed in this task, you see." Caster addressed Seyrun with a courteous bow before plastering on a bubbly smile. "Perhaps you'd let me return the favor? My Master and I could be of assistance in your investigation of the cities ley lines. You may not have a public interest in the Grail War itself, but surely other Masters and Servants will have an interest in securing the ley lines for their own interests, and would not be as discerning between Master and Magi as I am." She jiggled the bottle of alcohol, letting the sounds of sloshing sake ring between them. "Care to join us for an alliance over drinks?" 

Bubbly personality or not, she was still a courtesan of the imperial court, and one does not last long there without some skill outside of the carnal arts.

Reaching out for the link between Master and Servant, Tamamo initiated mental contact with Wes. [i]Master, I may have found us a potential ally for the course of the war in the form of a supposedly unaffiliated magus. Very clever girl, would have been proud to call her my rival in love if I hadn't already captured your heart![/i] She mentally tittered. [i]We shall likely be returning shortly, so it would be good to pull the boat to shore...unless you[/i] really [i]want to see me wet. [/i]
