Nina Harper's cousin, Petra (who's basically just a meaner/snobbier/bitchier version of Nina), is visiting Elkford, British Columbia from London, England. During the visit, Petra notices that Nina's still nursing a grudge against Sharon Spitz (Nina's BFF-turned-nemesis) for allegedly decapitating her beloved fashion dolls when they were little kids. Petra laughs at her cousin and casually (almost gloatingly) admits that she was the one who had done it—hearing this shocks Nina, as she had always assumed that Sharon was the culprit (despite never having any actual evidence to prove it).
Realizing that she's wasted basically half of her life being a jerk to Sharon for nothing, Nina makes an effort to patch things up with Sharon in the hopes of becoming friends again. Sharon initially (but understandably) refuses to go along with whatever Nina has in store—but with a little encouragement from Griffin (Nina's boyfriend's who also the son of Sharon's dad's girlfriend) and being given some time to think things over, Sharon decides to give Nina another chance. Sharon also notes that, if she and Nina do become friends again, it could mean the end of Nina's abuse towards her (and, by extension, Sharon's current circle of friends).
At first, things are nice, but Sharon soon realizes that becoming friends with Nina again isn't as cool as she thought it would be, as Nina forces her to do things that only [Nina] likes to do and is still mean to Sharon's current circle of friends. Ultimately, Sharon decides that patching things up with Nina just isn't worth it and chooses Maria, Connor, Alyson and Brock as her friends (which relieves them, as they were worried that Sharon was going to choose Nina over them).
Sharon's choice makes Nina mad and she and Sharon ultimately go back to being enemies—but at this point, Sharon doesn't care and figures that it's probably for the best. The episode ends with Sharon admitting in a voiceover, "Even though I hadn't decapitated Nina's dolls when we were little, a part of me kind of wishes I had" (after Nina had given Sharon the head of one her old dolls as "revenge").
This episode contains examples of:
- Disproportionate Retribution: Pretty much the whole that Sharon and Nina stopped being friends was because one day, while playing together at Nina's house when they were around seven-years-old, Nina saw that someone had decapitated all of her beloved fashion dolls—despite never having any evidence to prove it, Nina assumed Sharon had done it and subsequently ended their friendship. In the years that followed, Nina made it her personal mission the make Sharon's life (as well as the lives of anyone who would dare to attach themselves to Sharon) a living hell. It wasn't until well into their freshman year of high school (by the time they're around 14 or so) that Nina finally learned the truth of what really happened.
- The Fashionista: Nina and Petra are both this, being obsessed with fashion and their appearances. However, despite Petra claiming that she has better taste in fashion than Nina does, her taste in fashion is much gaudier compared to Nina's.
- For the Evulz: Petra doesn't really give a reason on why she decapitated her cousin's dolls when they were little kids, other than simply stating that she "was a nasty little brat" as a kid.
- Freudian Excuse: Petra's just as mean (if not meaner) to Nina as Nina typically is to others—it's probably safe to assume that Petra's at least partially responsible in Nina's turnout as a mean person.
- Heel–Face Turn: What Nina attempts to do the once the truth of the doll incident is revealed. However...
- Heel–Face Door-Slam: By the time Nina finally learned the truth, she and Sharon were teenaged high school students who haven't hung out together since they were around seven, and their interests have obviously changed significantly as they've gotten older. Plus, Nina only wanted to become friends with Sharon and continued acting like a jerk to Sharon's current friends (and basically everyone else).
- My God, What Have I Done?: After Petra casually (almost gloatingly) admits that she was the one decapitated Nina's dolls and not Sharon, Nina appears to be thinking this, realizing that she's wasted a large part of her life being mad at Sharon for nothing.
- Status Quo Is God/We Want Our Jerk Back!: Although Sharon and Nina do make an effort to become friends again (especially Nina), and while Nina has fun with what they're doing, Sharon just feels uncomfortable and ultimately chooses Maria, Connor, Alyson and Brock as her friends over Nina. Nina gets mad when Sharon chooses the others over her, but Sharon doesn't care, feeling that, at least at this point in their lives, the two of them are probably just better off as enemies than friends.
- Wham Line: When Sharon remembers that Petra was at the Harper residence the day of the doll incident and Nina once again accuses Sharon of being the culprit, Petra laughs at her cousin and drops a bombshell:Petra: When did you finally figure out that I was the one who did it?
