We Glee fans only got a taste of Idina Menzel last week after her duet with Lea Michele, but this week there was another duet and her own solo. Menzel is a Tony-winning Broadway star, and if anyone watching had never heard her sing before, they have to go back and get the original soundtracks of Wicked and Rent. If there was anyone out there talented enough to play Lea's more experienced mother, it would be Menzel, and she just rocked it on the show this episode. Hopefully it is not the last time the audience sees her.
Rachel realizes that Vocal Adrenaline is getting ready to do a big Lady Gaga number, so Will is determined to try and get in touch with Gaga's particular style too. Tina is not allowed to wear her goth clothes anymore because the principal believes in vampires, so he thinks Gaga might encourage everyone to explore wild costumes. Which of course they do, and the costumes are awesome. Apparently Lady Gaga gave either some of her old costumes or ideas for the designs, and they look marvelous.
Rachel goes spying on Vocal Adrenaline and she hears Shelby sing "Funny Girl," realizing it's the same voice from on the recording. She introduces herself and the two talk, but they have trouble bonding. Shelby is not getting anything out of this that she wants, and Rachel is awkwardly trying to learn about her mother. After a talk from Will, Shelby realizes she may have missed too much of Rachel's life by now, and that they might be better suited keeping apart. She gives Rachel a glass with stars on it (they are so alike), and the two sing "Poker Face." It's highly inappropriate, but a beautiful rendition all the same.
Kurt and Finn's parents are finally moving in together, and Finn is not okay with sharing Kurt's room. Unfortunately he has no real say in the matter, which is harsh and explains why he acts like such a brat later on. Kurt's crush has not gone unnoticed by Finn, and this situation has made him tense, so after Kurt rearranges their room to try and make it nicer, Finn snaps at him. Kurt swears he knows that Finn doesn't like him, but Finn says he hasn't accepted it, and uses the "f" word against the decorations he chose. It's as horrifying as any PC person can imagine, or anyone who hates hateful words like that. Kurt's father hears it and gives Finn a dressing down that is heartfelt, understanding, and firm. He'd used those words himself once upon a time, but now he's trying to change out of love for his son, and he won't accept Finn's hatred – no matter how slight – in his house. Finn is asked to leave, and Burt Hummel wins Best Dad on Television yet again.
In the end Finn starts to understand and realize he doesn't want to be that guy. He's being bullied by some jocks, as are Kurt and Tina. So he stands up for them in the end by wearing a wild plastic Lady Gaga outfit and the Glee club backs everyone up as a gang. It's nice, although a little silly with Will's slow clap in pride, but it was important for Finn to calm down. While Kurt's crush on him is intense and it might be uncomfortable to sleep in the same room as him, he has to find a valid and honest way to express that without resorting to personal insults.
Tina manages to scare the principal by declaring herself to be a vampire, and she can get her style back. The boys all sing a KISS song (in full makeup!) because they don't like Gaga, and the girls (and Kurt) all sing "Bad Romance." Every piece in this episode is well done. Puck then sings "Beth" to Quinn, suggesting the name of the song as a name for their baby, and saying that even if they give her up, he wants to be there at the birth. She agrees tearfully. It's very sweet, and a nice callback to the fact Quinn should be popping out her youngster any episode now. Likely in the finale, which is only a few weeks away!
Overall this was an excellent episode, and Lady Gaga must have been delighted to get so much publicity for it. Not like she needs it, let's be honest. The costumes were wonderful, and Mike O'Malley should absolutely get an Emmy nod for his supporting guest star role as Burt Hummel. Parents are usually either ignored, completely dysfunctional, or squeaky clean on television these days. He manages to play his role realistically and sweetly no matter what scene he's in. Everyone wants to have a parent like Burt Hummel.
