- While Hassan cruises around town with Lindsey, Katrina, TOC, JATT, and SOCT, Colin stays behind at home to work on his theorem; he's gotten it to work for everyone but K-3 and K-19.
- One night Hassan comes home with some juicy gossip of his own: he kissed Katrina.
- OMG, this is huge news. Colin can't believe it—he doesn't get why Hassan would go and do that when he's only supposed to kiss a girl he's going to marry (because of his religion).
- The two get in a huge fight about it. Hassan is ticked that Colin reacted this way, and feels like he finally has a story of his own to tell but Colin ruined it.
- The next day the boys complete some interviews, but they're still annoyed with each other and when they get home, Colin tells Hassan to quit making fun of him all the time.
- Hassan lets Colin know that he feels like he's listened to him whine about Katherines a million times, and he's upset that Colin can't be supportive of him now.
- The two duke it out some more, until finally Colin tells Hassan what's really bothering him: Hassan referred to TOC as Colin. This is a big deal to Colin who wants to be original and not just re-type or anagram everything in life.
- Hassan gets it and knows he messed up, so he apologizes.
- At the store, the two guys talks about Hassan's date that night. TOC is there too and he invites Hassan to go hunting with them next weekend; then he's gotta scram because he's going bowling with his buddies.
- Lindsey chimes in that she likes bowling—hint, hint—but TOC leaves without her. She pretends to pout until he leaves, and then she decides to take Colin out that night instead.
- The three of them head back to the house, where they find Hollis, annoyed that they are home before 5:30PM; they'd figured it would be okay since they're all going out that night.
- Lindsey confronts her mom about selling the land, but Hollis brushes it off.
- Colin works on the theorem and finally gets it to work right for K-19, which leaves K-3 as his only problem. Every single time he's worked on the graph for K-3, it's said he dumped her, which is ridiculous since he knows she dumped him.
- He doesn't have time to figure this all out, though, because he and Lindsey leave for dinner.
- She takes him to Taco Hell to get food, and then out to the field to practice shooting—he's never used a gun before, and she doesn't want his first time to be in front of TOC and the gang.
- Colin asks about a fence, and Lindsey tells him her horse used to use it. Her father gave it to her mom as a wedding gift and, after he beat it, her mom gave it to her.
- She teaches him how to shoot and get used to the kick back—she doesn't want him to look weak. Then she tells him about a top-secret hideout that no one knows about that she goes to when she wants to be completely alone; she asks if he wants to see it.
- Colin thinks back to getting coffee with Katherine. She asked him about Pythagoras and told him that he believed math could unlock everything (hmmm…sounds like someone else we know).
- Then Colin thinks about how K-1 became K-19 and took the throne that was hers all along. Yep—that's how he describes it.
