As for the first part, I think it's fair to say that Dexter was listening to his "bark" passenger at the moment, if you catch my drift.
As for the second, Dexter has basically become a surrogate-Wayne Randall, with all of the horizontal monster mashing that entails.
Speaking of monster mashing, off topic, but you put it into the joint Spotify playlist. Why would you submit anyone to that?
But on topic, I would monster mash her all day every day. Even if her daddy made her perfect.
Also I can't wait for the Dexter RPG made by BioWare. They actually have that scene and the paragon option is to kill her, the renegade option is to fuck her, and the neutral option is to sob and for spaghetti to come out of your pants as you leave sobbing like a baby.
