The time has officially arrived for Will and Emma Pillsburry's Valentine's Day wedding. Finn must contend with his guilt over kissing Emma in the previous episode, while Emma is convinced she won't be able to go through with the wedding. Many alumni of McKinley's Glee Club return, causing old relationships to stir up and new ones to be created. Jake enlists Ryder's help in giving Marley the perfect Valentine's Week as Ryder struggles with his own feelings. Artie is introduced to Emma's niece, Betty, who proves to be more than the average tough cookie, Tina is unable to hide her jealousy over Kurt and Blaine. After the wedding, Rachel returns to New York to face a major bombshell.
PlotA guilty Finn confesses to Rachel - who's in town for the Valentine's Day wedding of Will and Emma - that he kissed Emma in a heated moment. Rachel tries to calm him down, advising him to tap his acting skills by playing the part of supportive best man. Finn admits his fear of facing Will with Emma, but the stress of wedding planning has her in frantic OCD overdrive - she snaps at him to play his role and otherwise give her a wide berth. Will returns to McKinley from Washington D.C., and he asks Finn to sing a song in lieu of a best man speech, while the glee kids will provide the rest of the wedding entertainment.
Marley gives Jake an early Valentine's Day gift, and Jake fields less-than-helpful suggestions from his brother Puck, but Ryder offers a winning tip: "Instead of making it Valentine's Day, make it Valentine's Week." In class Jake offers a tribute to Marley with the glee guys backing him: the couple duets on Marvin Gaye and Tammi Terrelll's You're All I Need to Get By. Meanwhile, Finn and Rachel find themselves experiencing some familiar chemistry.
As the chapel fills up, Santana shares with Brittany and Sam an awkward wave, while Quinn is feeling burned by men in general. Assigned to be the escort of Emma's niece Betty, Artie is surprised to find the acerbic Betty less than thrilled to have him as her date, even though she's also in a wheelchair. Jake scores again with Marley by giving her peonies, her favorite flower, but Jake's successes are really fueled by Ryder's close attention to every detail about Marley. Kurt and Blaine have a steamy backseat hookup in the parking lot, but Kurt balks at labeling it a reunion. Mercedes interrupts them and tell's them to come to the church.
As Emma preps to walk down the aisle, Sue shocks her by wearing an identical wedding gown - revenge on Will for letting Finn run the glee club. Emma has a panic attack as the big moment nears, with Getting Married Today from Company providing a musical backdrop to her meltdown as she jumps in a taxi and flees the church, sobbing in the backseat. In full bridal regalia, Sue walks down the aisle to deliver the crushing news to Will.
Finn's guilt weighs heavier when Will assumes responsibility for Emma's cold feet, blaming himself for leaving her alone so long. Will insists the already-paid-for reception should go on, and Santana and Quinn bond there in their anti-romantic moods. Ryder slips Jake some jewelry to give to Marley but is put off when Jake suggests that he and Marley will be going "all the way" after his successful Valentine's courtship.Jake assures him Marley is special and reiterates his promise not to hurt her, but Ryder's having trouble putting his own feelings for Marley aside.
Kurt and Blaine entertain the reception with Depeche Mode's Just Can't Get Enough, while Rachel assures Finn that Emma's reaction was too extreme to be caused simply by his kiss. Artie takes another shot at Betty, breaking down her walls and scoring a dance with her. When Tina angrily tells Kurt she doesn't approve of the way he's been treating Blaine, Kurt accusing her of being "hagged out," creepily in love with Blaine.
Sue takes it upon herself to throw Emma's bouquet. It lands in Rachel's arms, prompting Finn to make a heartfelt pitch: despite her no-strings relationship with Brody, he believes he and Rachel are ultimately meant to get back together. They duet on Bob Seger's, We've Got Tonite, setting the mood for a series of romantic hotel hookups after the reception: Rachel and Finn, Kurt and Blaine, Jake and Marley, Santana and Quinn, and Artie and Betty.
Afterward, a happy Blaine wants Kurt to recognize they're back together, but Kurt remains noncommittal; Quinn tells Santana it was fun but most likely a one-time thing, though she's tempted back for one more round; Artie and Betty laughingly admit that neither of them knows if it was good for them; Marley apologizes for not going through with it, but Jake takes it in stride; and Rachel silently slips out while Finn sleeps.
Rachel returns home to find her apartment decorated with hearts and flowers by Brody - neither of them are entirely honest with the other about how they spent Valentine's Day. Tina admits to Kurt and Blaine that seeing their chemistry onstage has helped shake her out of her unrequited affection for Blaine, but Kurt can't help but downplay their relationship.
Marley gives Ryder a Valentine, admitting that she knows he played Cyrano for Jake and that his thoughtfulness was romantic - it'll be wonderful for him when it's for real with another girl someday. Ryder tells her it was real and impulsively kisses her, then apologizes. Both walk away confused.
Finn urges Will to stop moping and take action - it's the biggest lesson Will and glee club ever taught him.Will resists, wanting time to process what happened, but Finn promises to help Will find Emma and make things right. Betty surprises Artie at McKinley to apologize for her initial bitchiness and to tell him she was "the best she'd ever had," and Artie gets her number to take her out again. Artie tells her "anything could happen" as the New Directions start singing Ellie Goulding's Anything Could Happen while it intercuts with Rachel in her bed checking her calendar, Will going through pictures of Emma on his phone, and Rachel in the bathroom taking a home pregnancy test, which ends with her looking worried as she sees her results.

I kissed Ms. Pillsbury... like on the mouth.
Finn: I'm worried about being able to look Mr. Schue in the eye.
Emma: Get over it!
Emma: Uh, Sue...I feel really scared. I feel really overwhelmed. I feel like I can't think straight and I'm just really, really worried that this isn't going to work.
Sue: Well, of course it isn't going to work. You're a weird bird lady with a hallow pelvis and OCD, and Will Schuester is a weepy man-child who's greatest joy in life is singing with children. And his best friend: 19.
Emma: It's just the last time was such a disaster. I-I turned into someone I didn't recognize. If I'm wrong again, I won't survive.
Sue: Well, don't say that to Will Schuester. He'll have you singing a stripped down acoustic version of I Will Survive in a choir room full of teenagers with meaningful looks on their faces.
Today's the day we honor Saint Valentine! A man publicly beheaded for defying his government by exchanging candies and chocolates to nonsensically render the objects of our affection more fat and less attractive. And in other nonsensical traditions, Emma left behind her bouquet as she fled the scene, leaving it to somebody else to toss these soon-to-be dead flowers under the mythical belief that the person who catches them will magically be the next one who gets married. Or, more than likely, sprint from the alter. So gather around single ladies, and allow me to be the one to enable your false dreams and ridiculous expectations.
Tina: I don't like the way you treat Blaine. There, I said it. You're here. You're in New York. You're at vogue.com. You're at NYADA. Who are you Kurt? Meanwhile, Blaine is here lonely, and yes he cheated but we're all human Kurt, we all deserve to be loved back Kurt.
Kurt: Okay Tina, I say this with total love but the moment we all saw coming is finally here. You're a hag. You're hagged out, you're in love with Blaine and it's creepy. Stop.
Tina: What do you know about love? You just come and go. Who's been here to support him? Me. Who took him to Sadie Hawkins? Me. Who put him in bed when he got sick and rubbed vapor rub all over his little muscled chest while he slept-
Kurt: Wait, what? Did you, huh?
Tina: What? No. I didn't mean- This isn't about me Kurt! I have to go!
Kurt: Did you vaporape my ex-boyfriend? Don't walk away from me Tina Cohen-Chang!
Blaine: Tell me now that we're not back together.
Kurt: I mean, it was fun but--
Blaine: I'm not going to let you minimize this Kurt!
Quinn: So that's why college girls experiment
Santana: And thank God they do.
Quinn: You know it was fun and I've always wondered what it would be like to be with a women but, uh, I don't know. I think for me it was more of a one-time thing.
