It's time to get competitive on "Glee."While we loved the "Grilled Cheesus" episode (that Kurt sure can tug on our heartstrings), "Glee" is following that up with something lighter and more playful.In "Duets," we see first of all that Sam (Chord Overstreet) is now part of New Directions, probably since he just got injured on the football field. Mr. Schue is challenging the show choir to pair up and compete as duets. We wonder what the prize could be?It looks like Mercedes (Amber Riley) and Santana (Naya Rivera) are paired, and then Sam and Kurt (Chris Colfer) ... although why is Sam getting all tender and romance-y with Quinn (Dianna Agron)? Who's singing with whom here? Finn (Cory Monteith) then confronts Sam, "You tried to kiss her? Major glee party foul, dude." Okay, we're assuming he's referring to Quinn, but we could be wrong about that. Why would he be so protective of Quinn though? He's dating Rachel. We're not sure how much of this confusion is the promo editing or just Finn being irrational. We can't wait to see what's what.
