Open with Will (Matthew Morrison) and Sue (Jane Lynch) in a heated slow-mo argument. Via voiceovers we learn the origin of this "throwdown" came several days ago when the two co-directors had a meeting in Figgins' office.

They report to Figgins (Iqbal Theba) the new arrangement at the top of Glee couldn't be going better. In updates to Figgins we learn that some members of Glee are upset Will isn't selecting more modern, urban music. The Cheerios report this to Sue, who sees this as an opportunity to split the club. Will and Sue are each going to direct a song for the upcoming sectional competition. When Figgins makes them "hug out" the meeting, we see they still can't stand each other.

Quinn (Dianna Agron) has an ultrasound and learns she is having a girl. Quinn is still planning to give the child up for adoption, and Finn (Cory Monteith) is upset he has no real control over a stressful situation.

When Jacob threatens to run a blog post about Quinn being pregnant, Rachel (Lea Michele) offers to do she can to stop it.

Intending to paint Will as racially insensitive, Sue takes all of the minority members of Glee for her number.

Will tells Terri (Jessalyn Gilsig) he's tired of not having any involvement in their unborn son. He demands to be taken to the next OB appointment.

Rachel tells Finn about protecting him and Quinn. She had to give Jacob a pair of underpants, and Jacob wants a pair without a price tag on it.

Sue lets her half sing Jill Scott's "Hate on Me."

After the rehearsal, Will confronts Sue in the hallway about sabotaging (removing the piano, destroying sheet music) his practices. Sue confesses she is trying to destroy him and Glee.

At home Terri suggests Will get nasty in his battle with Sue.

The next day Sue learns most of her Cheerios are now academically ineligible after flunking Will's Spanish class.

In another meeting with Figgins, we learn the Cheerios are all terrible students and should have been failing Spanish for years. Figgins sides with Will.

Finn suggests a name (Drizzle) for the baby. Quinn thinks it's insensitive he is even talking about naming a child they will give up. He says he wishes she were more like Rachel. She warns him not to cheat on her with Rachel.

The entire club gets together on the sly and sings some Nelly. During Will's time he gives them their new song: Rachel and Finn will be doing a duet of "No Air." Previously coached by Sue, Quinn complains the rest of their half is relegated to back-up duty in the number. This causes all but three singers to leave Will's number and move to Sue's.

Will tells Terri he has made an appointment for that Friday with her obstetrician, Dr. Wu.

Sue tells Will she will give him back his singers if he passes her Cheerios. He says no.

Kendra (Jennifer Aspen) and Terri threaten Dr. Wu with a frivolous lawsuit if he doesn't help Terri fake her upcoming appointment.

Quinn tells Rachel to stay away from Finn. Rachel confronts Quinn about working on the side for Sue and warns her Sue won't be there once her pregnancy is revealed. This leads into Quinn and the Cheerios performing "You Keep Me Hangin' On"

Rachel, Finn and Quinn rehearse in front of Sue and the rest of Glee. When Sue starts to walk out, Will and Sue have the "throwdown" we saw at the show's opening. The result is all of the kids walk out of the room.

At the fake ultrasound Wu pretends Will and Terri are actually having a girl. Will gets emotional seeing images of his child. Terri pulls Will in for a kiss: "No matter what happens," she says. "I want you to remember at this moment that we love each other."

Sue agrees to give control of Glee back to Will.

Will tells Glee they are all minorities of some kind. Sue walks in and spills the beans that Quinn is pregnant.

Sue forced Jacob to go public with the story after finding Rachel's underwear in his locker. Quinn is beside herself.

The entire Glee performs Avril Lavigne's "Keep Holding On."
