We’ve already heard Finn (Cory Monteith) is back at McKinley High for Glee’s upcoming Season 4, Episode 5, and now we’ve learned that two more graduates will be joining him, as well!

Get ready, because both Mercedes (Amber Riley) and Mike (Harry Shum Jr.) are headed back to Ohio. The Hollywood Reporter reveals that the two will head back to McKinley to “lend Artie [Kevin McHale] a hand with a mysterious situation.”

On September 12, Glee creator Ryan Murphy tweeted this photo of all three grads back in the school auditorium. So far, the only other thing we know about this still-named new episode is that it’s also set to feature the debut of Glee Project winner Blake Jenner’s Ryder. 

But other than that? We have no clue. How about you: Any guesses what Artie’s big mystery situation might be?
