Will tells the Glee club they must perform at least one ballad at this year's sectional competition. They will use random pairings and work on singing to the partner. Puck is paired with Mercedes, Tina is paired with Mike, Brittanyis paired with Santana, and Finn is paired with Kurt, much to his embarrassment, as he initially wanted to be paired with Quinn and Rachel had hoped to be paired with him. As Kurt beams, Finn laments to Will that he doesn't think he can do it with another guy. Because Matt's absence (due to having a spider in his ear) resulted in an uneven number of participants, Will gets paired with Rachel, who wants to sing Endless Love. During the duet, Rachel begins falling for Will.
While trying on her dress for the Chastity Ball, Quinn's mother notices it no longer fits her and tells her to exercise more. Quinn's father pops into the room and tells Quinn he wants to have Finn over for dinner.
Rachel brings Will a gift, which sets off further alarm bells that she may have a crush on him.
Will tells Emma the tale of Suzy Pepper, a student from two years earlier who fell hard for Will. She also gave him a novelty gift and ended up calling his home in the middle of the night. When Will finally was honest with Suzy she ended up eating a super-hot chili pepper and having to be taken to the hospital. Emma suggest Will let Rachel down easy with a song.
Kurt insists that Finn sing to him "everything you feel" but Finn struggles and lashes out about the pressure he constantly feels, given all the things on his mind. He is bothered that his daughter may never know who he is. Kurt, after fleetingly mentioning that girls may be the base of his issues, suggests Finn try to sing away all of his problems. Finn performs I'll Stand By You. Carole catches him singing to a sonogram. He breaks down and tells her Quinn is pregnant.Quinn is furious Finn told his mother and is worried it might come back to her parents. Via voiceover Kurt tells that he has been "madly in love with Finn" ever since they crossed paths in the hallway (Finn briefly chastised Puck for running Kurt into the lockers) and is helping him so Finn will come crying to Kurt when Quinn inevitably blows him off.
With Emma in the room, Will sings a mashup of Don't Stand So Close to Me and Young Girl. Instead of listening to the lyrics, Rachel stares star-struck at Will, as does Emma.
Kurt helps Finn look through his dead father's nice clothes. With Kurt's mother having passed away as well, the two bond over losing a parent. Kurt tells him that there is a dresser that smells like his mother and sometimes he just sits on the floor and smells her. Finn is worried about meeting Quinn's parents and Kurt suggests he sing to them.
Will returns home to find Rachel has made dinner. Realizing Rachel had a thing for her husband, Terri allowed her to cook and clean their house.
Will drives Rachel home. On the way she tries to sing him Crush, but he cuts her off after a few bars. She tells him she's not interested in high school boys and has her "sights set much higher." The next day, Suzy Pepper corners Rachel in the hall and tells her to stay away from Will.
When Mercedes tells Puck the club wants to sing a ballad to Finn and Quinn, he blurts out that he is actually the father of her baby. Mercedes tell him it doesn't matter, that Quinn has made her choice and he owes her staying out of the picture.
At dinner, Finn begins to get nervous when Quinn's father makes a toast. He excuses himself and calls Kurt for help. He heads back out and sings (You're) Having My Baby to the whole family. Quinn's parents sit Finn and Quinn down. Quinn's father is so disappointed he kicks her out of house. Quinn is upset that her mother must have known that she was knocked up but did nothing out of fear of what Quinn's father would say if she said that she noticed Quinn had a big round baby bump.
Finn brings Quinn to his own home and his mother tells her she can stay with them as long as she needs to.
Suzy tells Rachel that after two years of psychotherapy she's learned that girls like them select crushes who will never like them back in order to re-affirm their low self esteem.
Rachel tells Will she knows they will never be more than teacher-student. She brings flowers as an apology and was going to sing "Sorry." Will assures her that someday a boy will come along who will like her for who she is.
Finn tells Kurt he thinks it's good that everything with Quinn and her parents is out in the open. Kurt tells Finn his song was going to be "I Honestly Love You" in a shallow attempt at revealing his feelings, but Finn remains oblivious and states that he's unfamiliar with the song.
The Glee kids sit Finn and Quinn down and sing Lean On Me in order to show them how they feel. During the song Puck and Quinn glance knowingly at one another. Kurt meanwhile gives Finn the "call me" sign, which causes Finn to look nervously taken aback.
