Gretchen is a Teen Genius.Gretchen joins the Cool Asians at the end, and is shown sucking up to them in broken Vietnamese. What does it say about her intelligence that she is capable of learning another language at a conversational level on her own, in high school, as a social activity? This may also explain some of her disillusionment with the Plastics, and in turn, why she was targeted by Cady, Janis and Damian to break up the clique — she might have been upset with having to hang around with people like Karen and Regina in order to be popular. And not for nothing, but she was the only brunette in the group.
Janis ruined everything.If one stops to think about it if Janis had never even placed inside Cady's head the idea of posing as a Plastic mainly/solely as a part of Janis's revenge scheme on Regina or (going further) if Cady had never met Janis (and through Janis) or Regina, Cady's entry into the American teen social ladder might have occurred much differently. As was stated by Damien at the start of the film Cady was a "Hot Little slice" that could easily become integrated into mainstream High School life that after only a small "Refinement" and update in her personal fashion sense, Cady would have been easily considered as or more attractive then any of the Plastics. Also Cady herself states that she was only acting "Bitchy" because she had to pose as this to fit in with a clique of other teen "bitches" as part of Janis's (and in part Cady's own) Revenge scheme and because of this Cady was unintentionally Becoming the Mask. Also it can be argued that Cady only acted in that way simply because she was totally unacquainted with a more "realistic" American teenager social structure and simply assumed that all popular girls acted in this way or manner. Finally Cady intentionally "Dumbed herself down" (although this was only to get closer to Reginas Ex not for revenge so YMMV on that one) degrading her persona (and grades) further. So simply put by the previously stated points without Janis's influence Cady could have still become the most popular girl in school by her own beauty, intelligence, and general kindness that she might have discovered or learned on her own and by others, and would have dethroned Regina as Queen Bee and taken over the plastics without destroying her own personal sense of character and/or reputation and morality. Now technically one can argue that Cady's moral and character decent was the entire point of the film It can be essentially said that Janis by her own childish need for "7th Grade" Revenge ruins the chances of this alternate scenario ever happening (including becoming one of the clique herself and a better friend of Cady later on). However in fairness to this it genuinely does appear that near the films end that Janis does realize what directly she had done to Cady and tries to make amends (in a small way), although she may never have realized exactly how much she destroyed as she unwittingly lost the possibility of future popularity, friends, and increased happiness not just her but the entire school Might have gained in the process. Instead of the reconstruction from the social ruins that are shown at the end of the film.
Regina spread the rumor about Janis being gay to hide the fact that she's gay.
The Debacle between Regina and Janis is based on a Sitcommy Misunderstanding that Ballooned over the YearsImagine if you will: two very close gal-pals in the 7th grade. One day, one of the two finds out about her Lebanese heritage. This gal never once hid a secret from her other friend, so she proudly tells her of her heritage. The friends, being a bit soft in the head and having rather unusual hearing, is led to believe that her friend wants out of the closet and, not knowing entirely better, she tells others of her dear friend's Lesbian identification. She tells these others not to tell and to act surprised when Janis comes out to them officially, but kids are vicious at this age and the rumor spreads. The Other realizes the error of her ways too late. Perhaps she tries to amend ways, but it does not matter at this stage. The damage is done and everyone shuns her close friend for a supposed orientation, ins pite of the gals' best attempts to tell their peers otherwise. Little Regina believes that her former friend can forgive her and that they can remain friends in spite of the misunderstanding, but Janis refuses to do so—she is embittered by the wrongful bullying and tells Regina that she acted foolishly. They break off their friendship. Alone in Middle School, fearing social ostracization and longing for the stability of companionship (even a fake one), little Regina attempts to make friends with the meanest group of girls. She even goes along with the rumor and no longer acknowledges the mistake by joining in mocking her former friend, Janis, in spite of knowing better—not out of malice at first, but a desire to disown herself of guilt by somewhat unconvincingly telling herself that her friend was secretly a Lesbian all along. Janis, angry at her friend's betrayal, lashes out and the two former friends become enemies. As time goes by, Regina's guilt evaporates and she mocks her former friend with ease—but she never feels comfortable with the "friendships" that she does make, never truly trusting her cohorts. She becomes manipulative, harboring secrets and playing on the insecurities of her "friends" to expose if they should leave or betray her, secretly fearing that it would all be her fault. This skyrockets her to the top of the meanest girls. Janis, meanwhile, is a social drifter until she meets Damien—perhaps in detention or at the desolate wasteland that is lunchtime. He heard the rumors and, upon meeting her, brings them up. She corrects him. He believes her, and the two become the best of friends. Although, Janis too is uneasy with friendships and, although she is builds up a trust with Damien and believes that he would never hurt her, she fears opening up to a friend and having those secrets misunderstood and exploited yet again. Enter: Cady.
The freshman Girl Posse that shows up at the very end of the first film is Massie and the Pretty Committee.
