Thanks to that pesky World Series it has been weeks since we’ve seen a new episode of Glee but luckily Kristen over at E! posted a few sneak peeks of Wednesday’s episode to hold us over!

“Wheels” has gotten a lot of attention from critics and is being hailed as the most “heartbreaking” episode yet. Included in the sneak peeks below are a look at Artie’s solo (Kevin McHale) and Will’s (Matthew Morrison) plan to teach the kids a little something about tolerance.

Finally, take a listen to a “diva-off” between Rachel (Lea Michele) and Kurt (Chris Colfer) while singing the Wicked song “Defying Gravity” which will air Wednesday at 9 p.m.
