We now know what Darren Criss was hinting at when he said earlier this week someone from his past would appear on an upcoming episode of Glee.

That person is Joey Richter, otherwise known as Ron Weasley in A Very Potter Musical.

Hypable had heard murmurs over the past week and had independently confirmed the news but kept it quiet on purpose. But now a new promo for Glee 4×11 “Sadie Hawkins” depicts Richter, and the secret is out.

Also in the episode is Tessa Netting – a friend to StarKid and the Harry Potter fandom. She was one of the original ballet girls, Susan Parks, in Broadway’s Billy Elliot.

You can seeboth of them in this photo (Tessa in the left circle, Joey in the right). They’re being observed by Glee character Kurt (Chris Colfer), who in the episode is being woo’d by a new Glee-esque club while he’s in search of a niche at NYADA:

“There’s somebody who’s going to show up in an episode, that if people know where I come from […] Someone’s gonna show up. It’s really great,” said Criss at Chris Colfer’s Struck By Lightning premiere last weekend. We had speculated that it was someone in StarKid and are happy to see Criss pointed us in the right direction after all. At this time, the roles of Richter and Netting do not appear to be recurring on Glee but that may change.

Glee 4×11 “Sadie Hawkins” airs Thursday, January 24 on Fox at 9 PM ET/PT.
