Glee-Cap: Feud.

History is full of famous feuds, I'm pretty sure the booming tabloid market can prove that - btw, Lohan vs. The Bieber is heating up, in case anyone was wondering. This week, feuds take center stage, and it's about to get real.

Blaine, Artie, and Tina call Will and Finn to meet over their feuding ways and declare it "Feuds" week and challenges their fearless leaders to find a famous musical feud and take their issues to the stage. Rachel finds out she's not pregnant, but Santana stops her blissful "it's all over" moment by reminding her that she can't just brush this aside, while Brody seduces a woman with a little Marina and The Diamonds "How to be a Heartbreaker" while Rachel agonize over what to do. Feuds boil over between Blaine and Sue about his lack of keeping up with the Cheerios, also Ryder gets a dash of drama from Unique for how he treated Marley and ruined her relationship with Jake. Will and Finn meet to discuss the assignment, but Will pulls out the big guns and dishes some harsh honesty, leaving Finn to man up and accept the challenge.

Rachel and Santana continue to fight about Brody, but Santana is ready to show Rachel what kind of guy Brody really is - feud on, bitches. Meanwhile, Sue steps her feud with Blaine, thus prompting her to channel him to a Nicki vs Mariah feud - which would if Blaine won, end his commitment to the Cheerios. Marley and Jake talk it out, while Unique and Ryder take it to the choir room and channel their inner Sir. Elton vs. Madonna mojo with "The Bitch is Back/Dress You up in My Love", but Ryder furthers the flames by refusing to acknowledge Unique as a girl. Wow, douchebag, right? Jake calls him on his douche move, but will that be enough? Guess Ryder will be getting back to his new online gal pal for him.

Santana crashes one of Brody's class at NYADA and gives him some straight up via Paula Abdul's hit "Cold Hearted Snake" before giving him an ultimatum - leave the apartment or be destroyed. Oooh, barracuda! At McKinley, Will and Finn take to the stage with a famous boy band feud - pairing "I Want It That Way" by the Backstreet Boys and "Bye, Bye, Bye" by NSYNC, but there's no harmony when Will can't find it in him to forgive Finn, prompting Finn to leave. Rachel and Kurt confront Santana about her actions, and proceed to give her a choice - lay off Brody or leave, thus prompting Santana to leave. Hey Lena Dunham, blow up that air mattress, Santana is coming.

Ryder's online gal pal gives him some truth about how he treated Unique, while Sue delivers straight up Minaj to Blaine's Mariah in "Super Bass/I Still Believe" and gets her way when she's declared winner. Hi, ho, Blaine Cheerio! Marley gives Finn a card thanking him for what he's done, but also lays down some harsh words, but Finn is too hurt to hear it, and leaves.

Ryder calls Marley, Jake, and Unique to apologize for his actions, but soon talk gets real when Unique reveals how she was taunted and teased about how he was dressed, which prompts Kitty to crash the party and join the fun. The newbies come together as they realize they need to stick together, because they're going to be the legacy soon once the seniors leave. Get it, newbies. Blaine rejoins the Cheerios, but while Sue thinks she's won - Blaine is planning to take her down from the inside. Santana surprises Brody at his usual haunts, but that's not the only surprise - a wild Finn Hudson appears. Brody and Finn throw down, and Finn tells Brody to stay away from Rachel, before storming out of the now destroyed hotel room. The glee club gets "Closer" with a Tegan and Sara hit, ending feuds and cementing friendships. Ryder wants to get close to his new online lady, but when he asks to meet, the conversation ends leaving Ryder confused and hurt.

It wasn't Lohan vs Bieber, but some sweet music came out of it, right? Next week - are you feeling guilty? Because, it's time to indulge in your guilty pleasures! Until next week, Gleeks!
