The core of Community, that core is the study group. A group of misfits from all walks of life, the study group has led a storied history across Greendale Community College, going on to conquer, fix, and cause the various obstacles within the school.
Like any good ecosystem, everyone within the study group has their place: Jeff is the leader, Annie is the brains, Pierce is the bankroll, and Britta, with the most important job of all, has to stay a safe distance away from everything. Far from a terrible character, Britta Perry sort of devolved across the story, moving away from bleeding heart to becoming the study group's airhead and punching bag. With a trying place in a group already filled with outcasts, Britta Perry has a few things about her life that are just too sad.
Her Life As An Activist
Britta self-identifies as a crusader for the betterment of her fellow man and the most pressing social issues of her age. It's just unfortunate that she's not much of a fighter. At her best, Britta has led social crusades that often alienate her own friends and the people helping her. At her worst, Britta doesn't contribute anything meaningful to a conversation other than her best wishes.
In "Geography of Global Conflict," she purposefully tries to get "oppressed" by the school through a variety of mild and convoluted annoyances across the school. In "Intro to Felt Surrogacy," she reveals that she's never actually voted (unless it's for The Voice). With very little action in her activism, Britta needs to stop trying to change the world and start changing herself.
Her Photography/Cinematography Skills
It's a bit of a stereotype that plenty of college girls try to get into photography as a means of purporting artistic skills. Britta Perry is the perfect example of this, as she's proved on multiple occasions that her best photographic quality is the fact that she owns a camera. In "Pillows and Blankets," Britta takes a variety of poor pictures in the midst of an actual, newsworthy battle on Greendale.
In "Advanced Documentary Filmmaking," she manages to catch the most important piece of evidence for Jeff's case against Changnesia but only by accident and after she fails to film a heart-wrenching interview with Shirley.
Her Psychology Skills
If Britta can't help the world, she might as well try to help people. In the later seasons, Britta came to realize her true ion in life and began studying as a Psyche Major, a trait that she proudly wore as if she actually had a Psyche degree. To an extent, she actually uses this well to help Jeff and Abed whenever they struggled with their personal issues.
In most other cases, she kind of drops the ball on being able to analyze people. She messed up on just the scanning portion of analyzing the study group's psyche tests and had a Freudian slip when looking at regular, test sheets. More often than not, she just enjoys getting to call herself a psyche major without much of the articulate tact that goes with it.
Her Love Life
Britta's relationship with Troy was a glowing element of the series but not because they went well together. Britta really needed a boy like Troy in her life given that most of her relationships have been toxic, destructive, and short-lived.
Britta's relationship with Jeff is a grand example of her attraction to emotionally distant men, and her infamous time with Blade showed just how obsessive she can be with the wrong people. The series even teased that she could fall in love with a random pizza guy with very little context. With a romantic life as rocky as hers, Britta's heart has more arrow wounds than actual arrows.
Her Cat Obsession
If she hasn't mentioned it enough across the series, Britta has a small interest in cats, as evident by the fact that she's adopted quite a few of them across the series. While these seemed to have been sadly abandoned during the later years of the series, Britta was the creepy cat lady during the early story who often tried to draw conversation to her cats.
When her cat, Suzie B., died, she was quick to replace her with Daniel. When Subway revealed his dream to help animals, she immediately asked if his dream included cats. Liking cats isn't necessarily a bad thing, but Britta, at one point, may have depended on them.
Her Constant Job Shifts
If anyone ever wondered how each member of the study group was able to pay for school, they can keep wondering with Britta Perry. In "Critical Film Studies," it was revealed that Britta struggles every bit as much in the workforce as she does at Greendale. With the same attitude issues and work ethic that plagues her studies, Britta was evidently a poor and unpopular waitress.
She has likely switched jobs quite a few times across the series, leading her to eventually run Shirley's Sandwiches which she would quickly turn into a bar. Given how hard it is for her to keep down relatively simpler jobs, becoming a psychiatrist (at least a trusted one) may be a pipe dream.
Her Money Troubles
As a symptom of her poor ability to keep a consistent job, Britta has often struggled with her finances across the series. She's constantly been in danger of keeping her rent (which inevitably led her to be homeless at the beginning of Season 6), often has to borrow money from the rest of the group, and was even called out by LeVar Burton for spending her money a little too easily.
According to Geordi La Forge himself, she's kind of stupid with money. Funny enough, this would lead Britta to reconnect with her parents again as she realized late in the series that the study group had been turning to them to help pay back her debts among a few other things that she's needed.
Her Rebellion Against Her Parents
Through most of the series, it was very obvious what the source of Britta's knee-jerk rebellion was. In "Introduction to Film," Britta blatantly projects her feelings about her own father as she berates Abed's. It wasn't until the episode "Lawnmower Maintenance and Postnatal Care" that fans would see how needless her rebellious side has been.
George and Deb Perry are, in fact, two very kind and ive parents who have been willing to accept every facet of Britta's being from day one and have apparently been ing her (but mostly her friends) in secret. In this case, Britta's hated her two closest allies since the beginning.
People Not Listening To Her
Britta's annoying legacy within Greendale has reached epic proportions on multiple occasions. Early in the series, people simply just got upset with her constant need to be heard and her wave of superficial social issues. As the series went on, that loud attitude just became a part of her school identity and the people around her just internalized not listening to her.
This is at full display in "App Development and Condiments" where, despite her sound advice, the entire school ignores her. It isn't until she rubs a few layers of mustard on her face to distract from her own, inherent coldness that people actually begin to listen to her.
Becoming A Term Of Endearment
There's nothing colder than having an entire term of endearment named after a person. Meaning a little more than to "make a small mistake," "Britta-ing" and "Britta'd" have become tossed around often since "Horror Fiction in Seven Spooky Steps." Much to Britta's disdain, the entire school has used her name to describe all manner of failures and shortcomings as a running gag.
While she's desperately tried to change that perception, she's only provided even more evidence across the story of how she can "Britta" like no one else. It's one thing to be the infamous airhead of a group, it's another to have all of those mistakes compartmentalized into an entire brand of its own.
