The point is made: being a 26-year-old virgin makes Shanna at least as "abnormal" as the people she mocks.
I like to think we're not totally riffing on the Takahashi "I hate you SO MUCH" relationship. At this point, I had no idea Shanna and Will would even be interested in one another. I expected Will to break up with Katherine but get back together with her later.
On the other hand, panel 3 was when I figured out we were gonna do something with Rikk and Rumy.
