Tina tries to intervene with Mike's father, but he remains convinced that dancing is too risky a path for Mike.

Tina reveals that Mike is doing what he hates just to appease his parents when he could be doing what he loves. Tina also reveals that she wants to be a performer someday, it's what she was born to do just as Mike was born to dance. She then turns to Mr.Chang and discusses honor with him, and how Mr. Chang does not honor Mike's gifts.
Sectionals this year are being held in the McKinley auditorium. Before the competition the Troubletones come to see the New Directions and tell them they are welcome to join the Troubletones after they lose, much to the New Directions' offense. Also Mike is angry at Tina for talking to his father. The Unitards—led by Harmony —are first, performing Buenos Aires. Quinn leaves the auditorium to tell Principal Figgins about Shelby and Puck, but Rachel stops her and urges her to warn Shelby first. Quinn confronts Shelby, who tells her that she is resigning from McKinley and apologizes to her.
The Troubletones performs next, singing Survivor/I Will Survive. New Directions then performs ABC, Control and Man in the Mirror, and Mike and Tina are surprised to see Mike's father in the audience. Afterward, he tells the couple that he now understands that dancing is Mike's passion, and Mike should apply to the best dance schools. At first Mike is disappointed because he missed the deadline, but Tina revealed she applied for him, causing Mike to proclaim his love for her in front of his father. At the judging process, the Unitards finish in third place, which Harmony is surprisingly proud to receive. She and Kurt talk before she walks off stage. Kurt believes Harmony is very talented, to which Harmony smiles at and reveals that she is only a sophomore so she's only going to improve. The Troubletones are then announced as second place as New Directions are crowned first. The crowd slowly disperses and the group are left alone on stage as the lights dim.
Quinn decides not to reveal Shelby's secret for Beth's sake. Outside Figgins' office, Quinn thanks Rachel for stopping her from doing something she would have regretted her whole life, and the two become friends She also tells Rachel that she's thinking of applying to the drama program at Yale thanks to her growing love of performing. Quinn then convinces Rachel and Mr. Schuester to promise to feature the Troubletones members in all future New Directions competitions if they agree to be in the group. Quinn meets up with Mercedes, Brittany and Santana in the girls' washroom to tell them that they don't have much time left together in high school, and lets them in on the plan. She invites them to join New Directions in the auditorium for a victory number and to get ready for Regionals, saying they need a few more girl voices. Mercedes, Santana and Brittany look pensive as Quinn leaves.
The girls, along with Sugar, show up in the auditorium and during We Are Young they start to sing and dance with the New Directions. Quinn waltzes Mercedes onto the stage, Sugar jumps onto Artie's lap, Rachel takes Santana by the hand and Brittany jumps into Rory's open arms.

- The title refers to Sam's favorite lyric in John Mellencamp's song, Jack and Diane, which he said to Quinn: "Hold on to sixteen as long as you can."
- Fitting with the episode's theme of age and maturity, New Directions' setlist for Sectionals chronologically covers a lifespan: childhood (ABC), young adulthood (Control) and adulthood (Man in the Mirror).
- This is one of three episodes submitted for the 2012 Emmys, the other two being "Asian F" and "Yes/No."
- When the Survivor/I Will Survive performance was originally uploaded early to the Glee VEVO channel (before said channel got deleted), the performance was slightly longer; the performance opened with all of the Troubletones' backs facing the audience before they all spun around one after the other (this was while we hear the opening music to the song just before Santana sings the first line). However, in the episode - this part was cut and you instead hear the opening music to the song during the end of Shelby and Quinn's scene prior to the performance.
- This is the episode contains the most amount of songs Quinn has sung in a single episode, singing in four songs.
- On the iTunes site of this episode, the summary for it includes "Harry", the name of Mike's portrayer, Harry Shum, Jr, instead of "Mike".
- The competition in this episode is the only one in which Rachel doesn't participate during her high school career.
- This is only the second time that Rachel doesn't sing in the setlist for a competition, the first time being 2010 Sectionals.
- When the New Directions are celebrating their victory, Artie is clapping and you can see Kevin McHale's tattoo on his forearm.
- Kurt mentions the ship RMS Titanic when he says "The Titanic has hit the iceberg and now we're on a sinking ship".
- When Sam returns to the Choir Room, Mike trips over his chair on the way to hug him, but plays it off.
- Quinn states that she is 17 in this episode. However she also says "I'm an adult" and six episodes ago (I Am Unicorn) Shelby said "you're 18." However, it's possible Shelby was a year off of Quinn's age.
- A cameraman can be seen during the scene between Finn and Blaine.
- When Tina goes to see Mike's dad, when she is about to leave she picks up the DVD and then when she turns around again the DVD is sitting on the desk again.
- Right before the competition starts, Will says that The Troubletones are on in five minutes, but the Unitards go first.
- After the New Directions are proclaimed winners, the clown throws the card that said one of the two remaining glee clubs, but in the next scene the card is gone, off the floor.
It was that damn Trouty Mouth! Even I felt a little something in my lady loins when he did that magic sex dance.
Rachel: We're kind of friends, huh?
Don't wish away your life. You're exactly where you're supposed to be.
