Sully's quick-on-her-feet "...yes" still makes me titter, because every time I read it, it reminds me of a routine on Seinfeld where Elaine is talking to two people, one of whom believes she's named "Suzie," about a problem between "Elaine" and "Suzie," and she actually manages to get away with it. "Yes! Yes, I'm Alisin! Alisin is me! That's who I am! Definitely!"
If Rikk had any experience at all with girls, he'd know that a line like "less comfortable," at this phase of getting to know one another, is a huge sign of danger (and not the fun kind of danger), but what guy hasn't dreamed it could be this easy? The dialogue porn movies are made of.
