And now, part 3 of the epic "Sarah talks to people" trilogy! Which, of course, predictably reveals at least four of the secondary male characters in this storyline are gay. It's pretty safe to assume that Cecil is heterosexual.
The origin for this was basically that I thought of the idea for the dialogue in panel one of this comic a while back, and things sort of escalated from there. And then I got other ideas. And then I laughed maniacally.
