McKinley High School is set to perform Grease as their annual school musical during Glee Season 4, Episode 6 — but Marley (Melissa Benoist) and the newbies won’t be the only ones getting all dressed up in classic ‘60s garb and tackling those beloved tunes.

We’ve already seen from earlier Twitter photos that Santana (Naya Rivera) will be back to join the McKinley kids during their production, and she’s sporting some sassy Rizzo-style hair.

But Santana’s not the only grad who heads back to Ohio for this newest ep. Rachel (Lea Michele) is there, too. On October 3, Lea Michele tweeted, “At work shooting a great musical number with the original New Directions! So happy to be back with everyone!”

She soon posted a photo of Rachel rockin’ a classic [end-of-the-show] Sandy look: sexy hair, tight black bodysuit, and all. We love the look — but wasn’t Sandy supposed to be Marley’s role? No fair stealing things from the New Rachel, Old Rachel! Geez.

Plenty of other grads have tweeted about their return to McKinley for this big Grease number, including both Amber Riley (Mercedes) and Harry Shum Jr. (Mike). Harry even tweeted a hilarious GIF that shows Santana and Blaine (Darren Criss) goofing around on what is unmistakably a carnival set.

Don't mix your words... @darrencriss @nayarivera #wankyseries

Look’s like “We Go Together” just might be the number of the hour! Our only question now: Who’s playing the Danny to Rachel’s Sandy?
