The New Directions are gathered around, sitting on chairs in a loose semicircle. MR. SCHUESTER stands at the whiteboard, writing “DUETS WEEK” in big letters.

MR. SCHUESTER: "Alright, guys, this week’s assignment is all about collaboration. It’s Duets Week!"

RACHEL: raising hand immediately "Mr. Schue, obviously Finn and I should—"

MERCEDES: cutting her off "Nope. No. We all know you two are gonna sing some mushy ballad and hog the spotlight."

KURT: sarcastic "What a shocking development that would be."

RACHEL: indignant "Excuse me, but duets are about chemistry."

SANTANA: leaning back in her chair "Yeah, and the only chemistry I care about is the kind that explodes."
