Jenna Darabond lied and said she was Ashley Katchadourian when she let Deandra into the girls room as part of a complicated Batman Gambit to incite chaos among the popular girls of Overland Park. That's why she's been offscreen so far, she's savoring the carnage from a safe distance.
Actually confirmed as of Episode 30 and 31. In the latter, Jenna admits she actually did lie and say she was Ashley Katchadourian to Deandra to set off a scheme that involved stealing Ashley's boyfriend and humiliating Mackenzie. She also admits to burning down the Atchison Mall to get Tanya involved.
A well-liked comment posed the theory that Connor Devarnon has genuine feelings for Brittnay, and only spread the rumor of her giving second rate handjobs so no one would want one from her anymore.
Ass Pull: The fact that Deandra was a registered midwife was not foreshadowed in any way, and is so far, not brought up again in the series.
Tyler Oakley's inclusion as the main casts' teacher.
As of Episode 70, fans are turning their back on Mackenzie, since it seems like Shay actually does not have a real cause for the other's and Brittnay's hatred of her.
Trisha being the one responsible for switching the tapes on the party with Shay's drunken rant, possibly causing her fall from popularity. Some feel that it's out of character for her to intentionally humiliate somebody, even if it is Shay. Then again, in Shay's rant, she also had not-so-nice things to say about her best friend Trisha 2, her boyfriend Matthew Derringer, and even Shay's own best friend, Saison.
Case in point, episode 14. Both Trisha and Mackenzie punch Brittnay in the stomach after incorrectly assuming she's pregnant to cause a deliberate miscarriage, Trisha because she doesn't want Brittnay throwing her life away, and Mackenzie because she doesn't want her ruining the national cheer competition for them. And then Shay punches her in the stomach, not because she thinks she's pregnant (she didn't even know about the pregnancy test), but because her sister Cameron asked her to.
Deandra's injury in Episode 11 is so Bloody Hilariousand horrifying at the same time.
Draco in Leather Pants: Fans often downplay various character's (i.e. Than, Brittnay, Mackenzie, Shay) meanness' in fanfics to make them appear more sympathetic than they would ever like to show.
Mackenzie, as of Episode 18. She gets her bald spot diagnosed and is especially torn when the doctor told her she's suffering from Female Pattern Baldness. She's utterly helpless when she tried to regress her anger in front of a rivaling cheer squad.
Than. Completely obnoxious, creepy, and insufferable, but it's clear he really does just want the football players to like him.
Brittnay would also count, if you feel sorry for her because her car got blown up by Mackenzie.
The entire squad (mostly sans Trisha for the Jerkass part) as of season 3. Sure, they may be giant bitches, but the New Year's Eve episode completely highlights the friendlessness the squad had going on and as of episode 40, they are so desperate for new members, they just hire anyone they know regardless of who they were.
Shay Van Buren, definitely—if you side with her. Just look at all the crap inflicted on her throughout the series!
Jenna Darabond. Episode 31 is a must see to see just how awesomely evil she is and nobody even saw her until two seasons later. Every major story line in the series that happened were all because of her.
She then gets one-upped by Mackenzie, who reveals that she set up the parent-teacher conference by instigating Brittnay into attacking Jenna via blowing up Brittnay's car so Jenna's dad would meet Cameron, Cameron would inevitably sink her hooks into Darren Darabond and end up destroying Jenna's family, and then recorded Jenna's confession of burning down the Atchison Mall which she brought to the police.
Moral Event Horizon: Jenna Darabond crosses it right off the bat in Episode 31 when she reveals that she was the one who burnt down the Atchison mallóbecause she wanted Justin all to herself. In the eyes of fans, she also crosses it by hating Amberlynn Weggers.
Trisha Squared/Trisha^2, or just Trisha (the two Trishas)
This was mocked by a drunken Shay in Episode 65, calling her teamup with Brittnay "Shittnay".
Purity Sue: Amberlynn, largely in that everyone loves her. However, since she doesn't appear that much, audiences like her just fine.
Also, it appears that not everyone likes her. Jenna Darabond seems to think she's an annoying bitch. So does Shay van Buren.
Rescued from the Scrappy Heap: The football team wasn't all that widely liked in the past seasons but since Deandra joined the football team on episode 41, a many commentators are already declaring love.
Deandra's big secret about why she left her old school. She had a failedPotty Emergency while on top of the pyramid during a cheer routine. The flashback shows extremely realistic-looking poop splatter all over Tanya, Taylor, and even the scoreboard!
They Wasted a Perfectly Good Plot: Season Four was hyped up as the "Brittnay Matthews: Mercenary Cheerleader" season, so naturally, a lot of viewers were disappointed when Brittnay only did that for about three episodes.
Uncanny Valley: The Damian Lewis doll that suddenly appeared at the end of episode 56 had some viewers aghast. Considering that the cast mainly consists of Barbies, action figures, and anything of the sort, his ultra-realistic features are jarring to say the least.
Played With. There's a minority in the fandom who believe that Jenna Darabond's fate was unjust as seen in Episode 39, she wasn't really evil in the beginning. Only after seeing Mackenzie break cheer code by making out with Ashley's then-boyfriend, Justin (who she has a crush on) was her Start of Darkness. Note that it's also Mackenzie who told Jenna that another cheerleader's boyfriend was off-limits. Brittnay making out with him at prom only added fuel to the fire. She even stated that she tried to be the bigger person by following that rule so one can see a little bit of justification as to why she hated them so much but it most definitely does not excuse her getting the Atchison Cheer Squad involved by burning down their mall, which is probably the most fucked up thing anyone had done out of all the characters. Even Brittnay's murder of the Expendables (Episode 67) was mitigated by the fact that they were trying to kill her, so it's mostly self-defense on her part.
As of Episode 70, Shay can be seen like this, when you consider how most of the bitchy things she's done are merely in retaliation against the Cheer Squad.
What Do You Mean, It's Not for Kids?: Trust us that this show is portrayed by little girls' dolls, Barbies, dolls of your favorite characters (Disney or otherwise), but it contains a lot of swearing that could fill up a jar that's enough to save a third-world country. That's not even counting the sex that some of these characters, have implied or confirmed, done before. And they're only in high school.
It gets even worse because of Episode 31 when we learn she was specifically set up to be blamed by Jenna Darabond so she could get Ashely's then-boyfriend Justin and has been The Chew Toy for the whole series. In episode 32 she asks to be left out of the ongoing strife between Mackenzie and Jenna, and Trisha speaks on her behalf. In episode 33, we learn from Ashley's little sister Brooklyn that Ashley has been depressed for a while and their mom is trying to help her.
