5. New guest stars and cast shake-ups!
Original cast members Brittany (Heather Morris), Quinn (Dianna Agron), Puck (Mark Salling), Mercedes (Amber Riley) and Mike (Harry Shum Jr.) are out as regulars during the fifth season. These beloved characters will only be appearing as occasional guest stars. To fill their shoes Marley (Melissa Benoist), Jake (Jacob Artist), Kitty (Becca Tobin), Ryder (Blake Jenner) and Unique (Alex Newell) are now series regulars. Rumored new characters include a love interest for Sam named Penny, an African American student named Ruby and a possible new male lead. Confirmed guest stars include American Idol runner-up Adam Lambert, who will play Kurt's new rival in NYC, and Demi Lovato, who will play Santana's new love interest, Dani.
4. Sue is coming back in a big way!
What can we say? There is no way to keep Sue Sylvester away. Last season we saw Sue (Jane Lynch) get fired after she took the fall for Becky's accidental gunshot fired on campus. The teaser for season 5 hints that Becky came clean and McKinley High's ferocious teacher is back, but (OMG) as principal of McKinley High.
3. Is this the beginning of Rachel's Broadway career?
One of the biggest questions from season 4's finale was whether Rachel (Lea Michele) lands her dream role in the revival of Funny Girl. Lea's recent tweets reveal that the new season will kick off with Rachel auditioning again for the role once played by her idol, Barbra Streisand. But will she actually get the gig? Here is to hoping!
2. Klaine and other couples news
So Artie and Kitty are reportedly the newest couple at McKinley High and now it is rumored that Ryder and Marley will get together. But wait, Marley and Jake may be a pseudo couple even though it was hinted that Jake will hook up with Ryder. Love triangle, maybe? But the real news everyone wants to know: What is going on the Klaine? Season 4 ended with one of the biggest cliffhangers in Klaine history. We saw Blaine (Darren Criss) secretly holding a little black box behind his back, but is there a ring in that box for Kurt (Chris Colfer)? We do know that Kurt and Blaine kick off season 5 locking lips.
Glee has paid tribute to big stars like Madonna, Michael Jackson and Britney Spears, but they are pulling out all the stops with a two-part premiere that will pay tribute to the Fab Four. This won't be the first Beatles song on Glee--remember Kurt performed of the Beatles' "Blackbird" in Season 2. No doubt it will be a fitting homage.
Glee returns tonight at 9/8c. What will you be watching for this season? Can't get enough Glee Beatlemania? Check out Darren Criss's quiz on all things Beatles!
