Tonight’s milestone 100th episode of Glee means that nearly all of the show’s original characters will be returning to Lima to bid the glee club that changed their lives a proper farewell. One familiar face featured in tonight’s instalment is none other than Dianna Agron, reprising her role as former head Cheerio Quinn Fabray, who is near the end of her freshman year at Yale.

Quinn’s long-awaited return to Lima is teased in the video below, and as we know she won’t be venturing to her hometown solo. Several months ago it was revealed that Gossip Girl alum Chace Crawford would be playing Q’s stuck up east coast boyfriend, Biff McIntosh, and now we have the first footage of the new couple in action. It looks like Biff’s in for a rude awakening as he heads to the midwest.

“I haven’t spent that much time around them, but poor people are generally less attractive than rich ones,” Biff tells his Quinn in the clip.

It also looks like this east coast preppy has a thing or two to learn about his gal, who may have “sugarcoated everything” for her buttoned-up beau. But don’t worry because Santana is there to fill in the blanks. “She dyed her hair pink, she got a Ryan Seacrest tattoo, and then lit a purple piano on fire ” Snicks says of her onetime bestie.

Biff may not fit in well with the Lima crowd, but Chace is actually quite friendly with several members of the Glee cast. Stars of teen dramas unite! “I know like probably more than half the cast,” the 28-year-old points out. “I’ve hung out with them at some point in time. I’m good friends with Matt Morrison, I know Dianna.”

We’re curious to see what the Lima crew thinks of Biff, but we’ll have to wait until tonight to find out. In the meantime, check out the clip below!

Glee airs on Tuesday nights at 8 p.m. ET on Fox.
