- ‶I am not cut out to deal with people. I was made to be in a lab or an operating room or a bunker somewhere with a well-behaved monkey by my side″
Paris is a brutally honest, very driven person who is not afraid to bring up awkward conversations, often resulting in people running away. She is also one of the smartest people at Chilton and maybe even Yale. She will go to any length to get into her dream college, Harvard. An over-achiever, she seeks out every position she can hold at Chilton, becoming both editor of the school paper, the The Franklin, and president of the student council.
Madeline Lynn and Louise Grant are her two seemingly oldest friends in high school, though she is very different from them. Madeline and Louise care more about boys and fashion, than they seem to care about school. Rory and Paris have an interesting relationship throughout the series. They start out as rivals, as Paris feels threatened by Rory, but slowly become best friends (with several roadblocks) and roommates for the rest of the series. Paris does not get accepted into her dream school Harvard. She then gets accepted to Yale.
Rory meets Paris on her first day at Chilton. Paris doesn't want to lose her top of the class standing, and feels that Rory could be the one to challenge that position, after sneaking a peek at Rory's grades. Paris has a huge crush on Tristin, with whom she went to school since third grade (who only had eyes for Rory), and her mom pays her cousin Jacob to take her to the school dance in their sophomore year. Paris even breaks the news of Lorelai and Max's relationship just to get everyone to stop talking about her parents' (very public) divorce. After a while, Paris comes to view Rory as less and less of a threat and the two even collaborate on occasions. When Paris gets an A-minus, she pleads for a reluctant Rory to study with her. Rory offers her to stay for dinner (because Jess drops by) and when a fight with Dean almost breaks out, Paris covers for Rory, knowing that Rory went out of her way to help her. Paris and Jess also meet for the first time and debate passionately about their literary favorites.
Paris forms a somewhat steady friendship with Rory from then onwards and asks Rory to be her vice-presidential candidate for student council. During their senior year, their "professional" relationship endures further conflict when Francie Jarvis manipulates Paris into thinking that Rory broke her trust by telling about her boyfriend, Jamie, who she met over the summer in Washington D.C. at the leadership camp she attended for student government. Paris and Jamie take the next step into their relationship, leading to Paris worrying if she made the wrong decision and turns to Rory for support. She is rejected from Harvard and has a meltdown live on C-Span, believing that Harvard punished her for losing her virginity. She spends the next 5 days in bed, watching soaps, refusing to call anyone or see what other schools have accepted her.
With some serious advice from both Rory and Lorelai, Paris starts to seriously consider what school she should attend: Yale, Columbia or Princeton. She accepts Rory being made valedictorian over her (after researching that they don't necessarily do too well in later life). During graduation she swears she does not recognize half her class and when Headmaster Charleston hands her her diploma and congratulates her, she tells him "No hard feelings". She and Rory say their goodbyes and hug while admitting that they spent most of the time hating each other.
Paris surprises Rory on her first day of Yale as her new roommate. Paris had arranged it after her life coach, Terrance, told her that her "journey" with Rory wasn't quite over. She joins the Yale Daily News and ends up breaking up with her boyfriend Jamie for an older man, Asher Fleming, who is a professor. Paris and Rory attempt spring break and try their hardest to follow the crowd: Getting wasted, entering "banana" eating contests, and ending in Paris kissing a disgruntled Rory. Asher dies over the summer between their freshman and sophomore year and Paris spends the beginning of her sophomore year grieving for him and sets up a wake. She makes fun of "Farmer boy" (Dean) re-entering Rory's life and begins dating Doyle McMaster, the editor of the Yale Daily News. Paris is shocked and outraged when Rory drops out of Yale, and turns straight to Lorelai where she admits Rory was the only person that always listened to her, challenged her, and will lose motivation without her.
She is made editor of the Daily News but becomes too power crazy and won't let anything go to print without it being perfect by her standards, which drives the rest of the staff of the paper to oust her. She is replaced with Rory, and a furious Paris kicks her out of the apartment. Rory has no other option but to move in with her boyfriend, Logan Huntzberger. Rory and Paris eventually become roommates again (along with Doyle), this time, with a binding lease so that Paris can't move every item of Rory's out into the hall again. In preparation for graduation, Paris institutes "Operation Finish Line," with Rory, an obsessive program designed to maximize their choices after graduation. This succeeds beyond her dreams, and she is accepted to multiple law schools and medical schools.
Paris is immediately distressed about finally having to make a choice that will have such a profound effect on the remainder of her life. To this end, in order to think rationally and clear her plate of any undue influence, she breaks up with Doyle. Doyle however, will not accept her breakup and vows to follow her wherever she goes. Paris then decides that she would be going to medical school as she had always dreamed to be a doctor. At their graduation she tells Rory that they're now on their own but Rory is still gonna do such great things with her life. Rory tells her that she hasn't been able to shake Paris off for years and no matter where they end up, they will still remain friends for a very long time.
Paris has an unrequited crush on Tristin, who is in love with Rory,
