Whatever happens in the finale of "The Leftovers," it will be definitive. This really is The End.

When HBO renewed "The Leftovers," it was for a third and final season, with just two episodes left at this point: Episode 7, "The Most Powerful Man in the World (and His Identical Twin Brother)" on Sunday, May 28, and the finale, "The Book of Nora," which airs June 4.

The show's fans are incredibly loyal, and can't really believe the show is ending after just three seasons -- and only eight episodes in this finale season -- when so many other less gripping shows go on and on. (Then again, ratings.)

The final episode, "The Book of Nora" is meant to take us back to that mind-trip of a moment from the end of the premiere, "The Book of Kevin," when an older-looking Nora Durst (Carrie Coon) called "Sarah" denied she knew anyone named Kevin. We know Nora actually knows two of them, both named Kevin Garvey, the father and son team played by Scott Glenn and Justin Theroux.

Showrunner and co-creator Damon Lindelof -- who will never leave "Lost" and its controversial finale behind him -- told Variety that everything will be wrapped up in the (hopefully) satisfying finale.

"This is it; we left no dangling threads, no to be continued, no spinoff possibilities. We made pretty sure that this was going to be the last season of the show. The audience deserves as satisfying an ending as we can give them. I don't think anyone wants to see a question mark at the end of this."

Nora herself, Carrie Coon, teased a "truthful" finale ahead:

"I think in a show like this, you can have a really explosive, shocking ending or you can have something that feels really truthful and I think that's what we have. I was so proud to be a part of it, and I'm a big part of it."

"The Leftovers" airs Sundays at 9 p.m. on HBO.
