Are you telling me you've never had anyone do that to you?

[It's clearly some kind of terrible betrayal. Not letting Quattro spoil him in such a way when he clearly enjoys giving Zechs a good time.]

Oh, Zechs, you've been missing out. I wish you had said something sooner. I feel as though I should have realized, but I thought you simply had other things you enjoyed more and asked for those instead.

[There's definitely a trend in the things Zechs asks for when Quattro gets him to that point.]
