Summer spies on Johnny and Marissa as they go into Chili's bedroom. Marissa puts her bag down and finds a picture of Johnny and Chili from their dorky-little-kid days, which doesn't really make sense if Johnny moved to Newport and met Chili only a few years ago. Or maybe they dressed up as Power Rangers when they were fifteen. Whatever. Embarrassed, Johnny grabs the picture away and hides it behind his back. Marissa giggles flirtatiously and reaches for the picture, putting her hands all over the guy who isn't her boyfriend. Summer looks pained. I guess the Dawn Patrol punch isn't sitting well.
Seth is lying on a pommel horse when his phone rings. He manages to extract it from his pants pocket -- not a small feat when you consider how tight his pants are. Being a hipster is tough sometimes. Summer's on the other end, and she says that Ryan needs to get to Chili's house right now! It's an emergency! Before she can tell Seth the melodramatic nature of it, Taylor Townsend grabs the phone away from him and lectures that cell phones are not allowed in the lock-in. Seth almost strangles Taylor Townsend, but manages to restrain himself and point out that the lock-in hasn't even started yet. Taylor Townsend doesn't care. She walks away with Seth's phone. I just want to know what happened to those Sidekicks everyone was walking around with last week. Ryan asks Seth what's going on, and Seth tells him that there's an emergency at Chili's house on Dune Road. Ryan takes off. Taylor Townsend reminds him that if he doesn't come back by 9, he'll be locked out and in a lot of trouble. Ryan doesn't care, because the day needs saving.
Marissa and Johnny check out Chili's CD collection together. Summer and Chili watch them from afar. Chili asks Summer why she doesn't like him. There are so many reasons -- starting with the fact that he calls himself "Chili" -- but Summer picks the one that's least insulting and says that she's already dating a dork. Chili says that just makes him more hopeful. He pats Summer on the leg, and she laughs. She's about three seconds away from wrestling with him over an embarrassing picture and then indignantly wondering why everyone seems to think she and Chili have something going on while she ditches her real boyfriend every chance she gets.
Casey finally shows up to the party, but pulls away from Johnny when he tries to touch her. Marissa manages to get a clue and makes an excuse to leave the real couple alone. Summer tries to call Seth to tell him not to send Ryan over after all, but Seth isn't answering his phone. Then Summer spots Ryan and tells him that her whole frantic call about Marissa being in trouble was just a false alarm, so he can go back to the lock-in. Ryan isn't buying it. The rocks in Summer's head can't think of an excuse, so she admits that Johnny and Marissa seemed to be getting a little too close, but now that Johnny's real girlfriend is here, it's obvious that she was getting worked up over nothing. Marissa walks out and asks Ryan what he's doing there. Summer lies that Ryan was making sure she would get to the lock-in on time. Then Johnny walks out and greets Ryan. He offers to get Ryan a beer, and Ryan says he'd love to stick around.
