'Community' Season Finale Sneek Peek: Jeff Is Graduating And Darkest Timeline Returns (VIDEO)

We don't know yet whether Thursday's "Community" season finale will also be the NBC comedy's swan song, but we do know that a key character has enough credits to leave Greendale Community College for good.

In HuffPost TV's exclusive clip (above) from Thursday's episode, "Introduction to Finality," the study group discusses Jeff's imminent graduation and what that might mean for the gang's collective future. Thursday will also see the return of the Darkest Timeline, which fans famously glimpsed in the classic episode "Remedial Chaos Theory."

Will Jeff leave Greendale? Will "Community" return? Will members of the study group don Darkest Timeline beards? What kind of costume will Dean Pelton wear to mark the end of another semester? We'll have to tune in for the "Community" finale to find out.

The "Community" finale airs Thursday, at 8 p.m. ET on NBC.
