Summer was about to go on an overseas trip to Italy with Zach and his family, when the feelings she still had for Seth prevented her from doing so and she left her heartbroken Zach at the airport, going back to Seth. Zach returned later on in the season however, and this along with Zach and Seth once again going into a partnership for a comic book strained her relationship with Seth. Zach also somewhat subtly exploited this to weaken Seth and Summer's relationship and restart his relationship with her, causing something of a love triangle. The introduction of Reed, a female attractive, older comic book executive who Seth was not initially truthful about also caused difficulties. This was eventually resolved when on the day of the Junior Prom they flipped a coin as to who would go to the prom with Summer and who would meet George Lucas for a comic book project meeting, with Zach winning the date with Summer.
