Glee Season 4 finale spoilers are about some lingering issues among this year's characters, including bits about Finn Hudson. But the Finchel (Finn and Rachel Berry) couple is not likely to be seen together. Lea Michele has teased fans to expect some "shockers." Meanwhile, we still haven't heard of an official Glee Season 5 confirmation.

Cory Monteith, the actor who plays Finn, has checked himself in to a rehab to combat substance addiction. This means Finn will be MIA in the Glee Season 4 finale in May. But series creator Ryan Murphy has told fans Finn's situation will be explained, anyway. The last time we saw him, Finn showed Brody some fist power to protect Rachel from the gigolo. Oh, and let's not forget he kissed Emma on impulse. Will the latest Finn update in the finale be Rachel-related?

"Just finished reading the final script of #Glee for this season! So many shockers and huge cliffhangers," Lea Michele shouted out on Twitter a week ago. This was a day before the airing of the controversial "Shooting Star" episode.

What shockers and cliffhangers await the viewers of Glee Season 4 finale? Last week's "Shooting Star" episode was a major shocker in its entirety. The "I-don't-work-here-anymore" line by Sue Sylvester has sparked several speculations, too. Will viewers miss Coach Sue in the finale?

Expect Sarah Jessica Parker, Kate Hudson, and Idina Menzel to reprise their roles in the last few episodes of Glee Season 4. American Idol 2012 runner-up Jessica Sanchez is showing up soon, and she will appear in the finale, too.

After this week's "Sweet Dreams" (Episode 19), only three episodes will be left to run in Glee Season 4. Fox has revealed in a statement that the penultimate season episode is called, "Wonder-ful," and Glee Season 4 finale will be called, "All or Nothing."

Here is what Fox has told entertainment sites about the Glee Season 4 finale:

"The members of New Directions travel to Regionals. But the competition gets tough when they go head-to-head with the Hoosierdaddies and lead singer Frida Romero (guest star Jessica Sanchez). Meanwhile, Rachel finds out if she gets the callback for "Funny Girl" on Broadway."

Glee Season 5 rumours are making fans anxious. It remains unclear whether Glee will come back for a fifth season due to the busy schedule of its showrunners. Murphy and company have yet to officially agree to another season, according to rumours. (Fans cross their fingers.)
