Shinobu
Her cute minion was reacting so adorably to her teasing, she did of course expect the question, it simply made it easier for her to continue. How to answer the question was different matter however, perhaps....she should talk about the previous one she had turned. Considring who Medaka was and how she looked, that could prove rather entertaining if done in the right way.
"If I have ever been attracted to them? I could tell you about the previous person I turned. I am quite certain he would take a liking to you....with how short your skirt are and how much of those enormous breasts you are freely showing off, you would be quite to his taste. Now that I think about it his harem did lack a student council president, oh that's right I didn't tell you." Her hands had started to lazily rub the lower end of Medaka's back after moving from her ass.
"My previous underling had quite the harem, even if he would vehemently deny it....As if your average high school boy has a girlfriend. lusts after the class representative, takes bath with a vampire, molest a ghost and gropes his own sister....Oh you wanted blood did you not." Shinobu suddenly changed the topic mid sentence and tilted her head sideways, baring her neck for Medaka.
Jeanne
The blond saint tried her best to ignore the drunken behaviour Shirou was exhibiting, the way he was not so subtly ogling her assets wasn't the appopriate response to what was going on right now.
With the strange appearance of the demonic being and their encounter with another servant, the situation was tense indeed, although it seemed both of the men was unaware of it, one being drunk and the other probably frightened.
She couldn't ignore that Shirou had outright called attention to Petra being a Servant, that had to be smoothed over somehow, the other saint already looked angry. She guided Shirou over to the couch and sat him down before turning back to Petra.
"I come before you as a servant of The Lord and I wish to extend to you all the respect you so deserve." Jeanne bowed in reverence to the brown haired Saint. She hoped that the woman would understand she wasn't there on Grail War related business, that however didn't make the act itself any less genuine as she did possess a fair amount of respect for who the woman was.
