Check out another sneak peek for next week’s episode of Glee. Dianna isn’t in it but it is a Quinn related scene.

Next week’s episode of Glee is titled “Prom-asaurus” and fittingly so, given Brittany’s elaborate dancefloor performance of Ke$ha’s “Dinosaur.” Brit and the dinosaur-masked Cheerios break out some elaborate choreography, and the clip also reveals a nervous Finn (Cory Montieth) looking for an MIA Quinn (Dianna Agron). Where could she be?

Watch over at EW.

Brittany’s quest to throw the most dino-mite prom McKinley High has ever seen on Tuesday’s Glee (9/8c, Fox) leads the lovable dimwit-asaurus to impose some controversial restrictions on her classmates.

Given the dance’s prehistoric theme, Brit announces that hair gel will be banned from the event because the sticky stuff “wasn’t invented until almost 30 million years after the Upper Paleolithic Stone Age.”

She then turns to a horrified Blaine and sneers, “And, frankly, I don’t like the way you look.”

And wait until you see what Ms. Terror Nova has in store for Santana and Quinn.
