Glee Season 4 Episode 21, "Wonder-ful," will see some McKinley High graduates coming back to Lima -- perhaps to show support for the upcoming Regionals in the finale. Kate Hudson reprises her role as Cassandra July. How will her character affect Rachel Berry's hopes for her 'Funny Girl' audition?

Glee Season 5 is just around the corner. Viewers are certain with a Season 6, too, but that is getting way ahead of the story. For now, the cast celebrates the Fox nod for another year of show choir fun. But rumour has it a current regular character will not be returning in the same capacity next season. Any guesses?

E! Online reports the character who will have a much smaller role on Glee Season 5 is someone in this photo:

Those who know of Heather Morris' first pregnancy might not be surprised about this news. Then again, is it safe to assume no one else is at risk of having a lesser role on the show?

Here are some things we expect to see in the Glee Season 4 penultimate episode:

1. The Gleeks will be performing some Stevie Wonder songs.

2. Artie's mom will make an appearance to relay some important news that could affect his future.

3. Mike, Mercedes and Kurt will be prancing on the hallways of McKinley High.

4. Blaine will shock Kurt's father with a big announcement.

5. Cassandra July and her gorgeous abs will react to Rachel Berry's 'Funny Girl' callback hopes and dreams.

Glee Season 4 Finale Spoilers: Obviously, no Nationals just yet!

If Glee is doing some Regionals preparation in its penultimate episode for the season, viewers can be certain there will be no Nationals until next season. This also means no graduation just yet. (How will the aforementioned rumoured series regular have a lesser role?)

"We're doing some weird sh*t on the show, just wait," Glee showrunner Ryan Murphy told The Hollywood Reporter in an interview. "I don't want to do what we've done every year; I want to do something different."
