Glee's 100th episode will feature the reunion of most of the show's original cast members, and fans of one pair of characters will be treated to some good moments between the two of them.
Glee actors Harry Shum, Jr. (who plays Mike Chang) and Kevin McHale (Artie) spoke with The Huffington Post recently about what to expect from the 100th episode. Shum mentioned the return of a story line involving Santana (Naya Rivera) and Brittany (Heather Morris).
"There are some of those Santana and Brittany moments that we've all been missing," he said. "I'm a fan of those story lines, too, so I'm excited for people to see that."
Brittany was last seen in the season 4 finale All of Nothing, though she has been mentioned in select episodes of season 5. Her portrayer Morris was downgraded for season 5 due to her pregnancy.
McHale told The Huffington Post that he is still shocked that he has been a part of something as big as Glee.
"All season I've been going, 'This is my 92nd episode, this is my 93rd,'" McHale said. "Growing up, I'd always see how Friends and all these shows go on and on and on. They talk about going hundreds of episodes and I never thought I'd be a part of something like that."
The 100th episode of Glee will air on Tuesday, Mar. 18 at 8 p.m. on Fox.
Glee season 5 returns for its midseason premiere on Tuesday, Feb. 25 at 8 p.m. on Fox.
