|During Jeff's first week at Greendale, he met fellow Spanish 101 student Abed Nadir and tried to get the attention of another classmate named Britta Perry. This involved forming a fake Spanish study group which backfired on him when she invited Abed and he in turn invited Annie Edison, Shirley Bennett, Pierce Hawthorne and Troy Barnes. He also attempted to convince his former client Professor Ian Duncan to help him cheat on his classes. Despite Jeff's best efforts he was unable to manipulate either situations to his favor. Exposed as a fraud to the study group and taught a lesson in cheating by Duncan. While he contemplated his next move, he crossed paths with the study group who took pity on him and allowed Jeff to rejoin them ("Pilot").
Jeff became the de facto leader of the group much to Britta's annoyance. They were all charmed by him particularly Pierce who wanted to be his best friend. When the Spanish teacher Ben Chang paired up the class for an assignment Jeff tried to become Britta's partner. Instead he wound up with Pierce who attempted to turn the simple assignment into a big production. After wasting several hours, Jeff left Pierce to join Britta at a protest she was attending. A drunk and angry Pierce showed up and made a spectacle of himself. The next day in Spanish class, Britta guilted Jeff into doing the presentation with Pierce. Jeff made up with Pierce but despite all of their pomp and circumstance they end up getting an "F" ("Spanish 101").
Jeff signed up for an Accounting class taught by taught by Professor Eustice Whitman having heard it was an easy "A". Whitman was influenced by a certain movie and Jeff unexpectedly found himself struggling with his assignment to "Seize the day". At the same time he got wrapped up in some family drama due to Britta pushing Abed to take a film class over his father's wishes. Abed casts Jeff and Britta as his mom and dad for a film assignment he is doing. He later shows the completed projected to Jeff, Britta and his father which convinced Gobi to allow his son to pursue his dream. As a reward for helping her and Abed, Britta kissed Jeff in front of Whitman who declares he finally passed his assignment ("Introduction to Film").
A disciplinary tribunal consisting of Dean Pelton, Duncan and Chang was held in Borchert Hall to deal with Britta who admitted to cheating on a Spanish test. Jeff volunteered to represent her but found his efforts hindered when she confessed her guilt. During recess she accused Jeff of only wanting to help her so she would sleep with him. Jeff admitted it was part of the reason but his main focus was trying to help a friend not get expelled. Britta revealed getting caught was intentional as she was driven by her fears of inadequacy. Jeff used her damaged psyche as her new defense and got her sentenced to a years worth of therapy sessions from Duncan. Afterwards, Britta begrudgingly thanked Jeff as they watched Pierce perform the new school song on the quad ("Advanced Criminal Law").
When Jeff refused to be a part of Greendale promotional materials he got blackmailed by Dean Pelton to recruit Troy for the football team. Annie is upset when he succeeds and Jeff points out that she just selfishly wants Troy all for herself. Annie doesn't deny this but counters that unlike Jeff she actually cares for Troy. Later, Jeff went to the gymn where the football pep rally was being held. Jeff confessed to Troy how he manipulated him into becoming a quarterback again. Troy didn't care as the team was so horrible it allowed him to play for the love of the game free of pressure. Outside the gym Jeff ran into Annie who showed up to support Troy and apologized for his actions. They were interrupted by Pelton and Pierce who introduced the school's new mascot ("Football, Feminism and You").
