The list of familiar Glee folks who will be appearing in the show's upcoming 100th episode extravaganza is getting to be about as long as Santa's list. Unfortunately, we're now learning that one of the original cast members won't be in the episode. Sad face.

Glee will hit the 100-episode mark with Season 5, Episode 12, which is likely to air on March 18, 2014. And the episode will be quite the reunion, as such beloved characters as Quinn (Dianna Agron), Brittany (Heather Morris), Puck (Mark Salling), Mercedes (Amber Riley), and even April Rhodes (Kristin Chenoweth) will grace the show with their presence. 

However, one character who was a mainstay on Glee's early seasons is not likely to join the fray for the 100th episode. TV Line is reporting that everyone's favorite pregnancy-faker, Terri Schuester (Jessalyn Gilsig), will not appear in the episode. We suppose this means no Howard Bamboo either.

To be fair, Terri's absence kinda makes sense, since the show seems to have exhausted any possible Terri-related plotlines. Plus, the episode figures to be quite music-heavy — as fans' ten favorite Glee tunes will be performed — and Terri has never really done much singing. 

Still, we're curious to get an update on Terri, who hasn't appeared since Season 4's "Glee, Actually," in the alternative-universe storyline. Can someone please pay a visit to the Miami branch of Sheets-N-Things and tell her we say hello?

Are you bummed that Terri isn't appearing in the 100th episode?
