Mario "interviews" Beatrice and Carly backstage like he works at the day care center they go to, and then Khloe introduces Arin to sing for his survival in the competition. He comes out looking as pissed off as he did when he wasn't named in the first place, and sings "I Look To You" while Britney sits patiently waiting for it to be over. Or at least she does until he careens into the last chorus, at which point her face turns into "Wait, what?" L.A. tells him he doesn't know why he even has to try to save himself. Please don't encourage Arin's increasingly entitled attitude, L.A. Demi talks about how much the girls love him and agrees with L.A. Simon says this was a different league from Arin's performance last night, and that his leaving would be a huge mistake. And since it's Britney Spears's mistake to make, Arin looks rightfully terrified.
It's Diamond White's turn, and tonight she's here to sing "Sorry Seems to Be the Hardest Word," something that sounds pretty grown-up for somebody who has Mickey Mouse hands all over her shirt. She does pretty well, while the camera keeps cutting to Britney waiting for it to be her turn to talk. L.A. says she gives him "chill-bumps" and that she has a real future in the business. Demi was impressed by Diamond's soul, and Simon says he'd hate to be Britney, because Diamond totally changed his mind in the last twenty seconds of her song. In fact, he doesn't think either of them should have to go, so I guess Beatrice Miller should count herself lucky that Simon doesn't march backstage and boot her himself. Arin comes back out, not helping himself by looking annoyed at this whole situation while Diamond keeps on smiling. Britney says it's a tough decision, but she's sending home Diamond, stunning both of them. Arin takes off while the hosts patronizingly buck up Diamond, whose post-defeat period of depression lasted all of two seconds.
