- Still on the floor from hitting his head, Colin's mind whirls with a bunch of thoughts, some of which he decides to write down. He sketches a graph and he thinks about it representing his relationship with Katherine-19.
- While all this is happening, Lindsey and Hassan are trying to figure out if he's fine. Lindsey asks the typical what-day-is-it type of questions to see if he's lost his marbles, but Hassan takes a different approach and asks Colin random factoid questions that no normal person would know. Lindsey is super impressed when Colin answers them… although no one really knows if he's correct or not.
- The conversation turns to Colin's graph in his notebook. He wrote it about his relationship with K-19, but Hassan thinks it will work for any relationship. Woosh (that's the sound of our minds being blown).
- Colin fills Lindsey in on the fact that he's only ever dated Katherines. Lindsey's all ha, ha, that's funny, but no one realizes why. Then she breaks it to Colin: she's only ever dated one guy… and his name is Colin.
- Colin takes us back to the third grade, when he only attended school for three hours a day so he had time to visit his Volvo-driving psychology professor/tutor, Keith Carter, a.k.a. Krazy Keith.
- The guy would let Colin read and then quiz him on the book he picked. Colin lets us in on the fact that he wasn't a genius or anything; he just spent more time studying than everyone else.
- One day Katherine came to visit her dad (Krazy Keith) and watched Colin study. She asked him why he was reading, studying, and learning Latin, and while Colin could answer easily at first, after a while he too became fascinated with the why. Why was he studying Latin, or reading Ovid?
- After this why game, Katherine randomly asked Colin if he wanted to go out; he did, so she kissed him.
