"HOME AGAIN, HOME AGAIN, LOTS OF LOVE"-
Coming to Fox this April, a look inside the home lives of the members of New Directions as they prepare for nationals.

Tina (Jenna Ushkowitz), desperate for a solo, attempts to convince her parents Evelyn (Margaret Cho) and Jimmy (Ken Jeong), that voice lessons might be the key to gaining a competitive edge over Rachel, who could pee on stage and still get a solo, and Quinn, who's played by Dianna Agron. Her parents, boyfriend and ex all convince her that she's good enough to earn the solo on her own, but the truth is that they've spent all her voice lesson money on bling for their dog.

After repeatedly discovering deeply-worn-in Cheeto stains on her son's mattress, Carole Hudson-Hummel (Romy Rosemont) sends Finn's mattress away to be steam-cleaned. Upon its return (and Finn's return from a boys-only camping trip with Puck and Mike), Finn discovers that the mattress has shrunk and accuses Kurt and Rachel, his shorter stepbrother and ex respectively, of plotting against him.

Meanwhile, Kurt discovers that Blaine (Darren Criss) has been struggling academically since Kurt's departure from Dalton Academy and offers to help the fellow junior out with his homework. Blaine is hesitant to invite Kurt over and so Kurt, not at all creepily, follows Blaine home one day only to discover that his boyfriend lives in a closet under some stairs.

Sam (Chord Overstreet) falls asleep in his parents' basement and wakes up in an internet meme. He is horrified to learn that he is unable to escape it, but he quickly uses it to his advantage and suggests to Mr. Schuester that he perform "Chocolate Rain" at Nationals. Mr. Schuester, while impressed that Sam is willing to explore his lower register, informs young Mr. Evans that the song is a "downer" and offers a more upbeat song from Communist Russia instead.

Mike (Harry Shum Jr.) learns that his father has become a motivational speaker. Empowered by his father's teachings, he tells Mr. Schuester that he is finally ready to perform a solo in front of the class. Tina is tremendously proud of him, but before he can begin, Artie (Kevin McHale) interrupts him to perform Rick Astley's 1987 hit "Never Gonna Give You Up." Rachel learns an important lesson about irony as her wheelchair-bound classmate "rickrolls" the Glee Club, and Tina's outrage at Artie's interruption of Mike's vocal debut quickly turns to admiration and the two escape the classroom to reconnect. Mike is momentarily heartbroken to so publicly lose his girlfriend, but Sam reminds him that all he needs to do is talk to his dad and look at a reflection of his abs and everything will be OK.

Lacking in a supportive male influence and not having quite the connection with Mr. Schuester that Finn does, Puck rekindles his friendship with Artie. Artie helps him reconnect with his "hood" side, but Puck's new choice in clothing enrages Principal Figgins (Iqbal Theba) who calls an emergency assembly to admonish the students who insist on "walking through town with their pants on the ground."

Sam falls asleep again, this time in class. He hallucinates Brad (Brad Ellis) as Keyboard Cat, and a mysterious stranger as his co-star in a hilarious cover of A-Ha's hit "Take On Me." He can't tell if it's Quinn or Kurt. He is woken up by an accidental elbow to the head by Santana's new love interest, Jane Anderson, Blaine's Hot Lesbian Sister (Camilla Belle). Brittany, having bonded with Sam over their mutual learning disabilities, is convinced the elbow is intentional and gets in a knock-down-drag-out fight with Jane. This turns Santana on, as well as Mike, Finn and Puck, but does nothing for Kurt, Sam or Artie, though with the latter this is not an issue of sexuality but rather due to the fact that he is implied to be engaging in intercourse with his on-again lady-love in a corner. This behavior is not visible due to Glee's TV-14 rating and the producers' desire to deprive Tina of screentime.

The end of the week is nigh and the students in New Directions, having learned many a lesson, are hesitant to let the week end. Their inspiration comes from an unlikely source, a forty-something cheer coach in a black wig, surrounded by an entourage of blue-suited prep school boys as she extols the benefits of getting off of school property.
