After a brief hiatus, Glee Season 4 returns this Thursday with an episode dedicated to the movies.

A week later, however, the focus will move from filming to feuding, as tension arises between Will and Finn. Big time.

In our first look at the March 14 installment (aptly titled "Feud"), we see these two staring daggers at each other from across the stage, while also getting a look at an upcoming performance and Kurt and Rachel looking sullen in NYC. Click through the images now:

Fox has also unveiled photos from the March 21 episode, "Guilty Pleasures."

Why is Kurt examining himself in the mirror? What is taking Santana and Rachel by surprise? Who is taking center stage for a performance? Visit our GLEE PHOTO GALLERY now to take another look ahead at scenes from that hour.
