The season 4 finale of 'Stranger Things' will be almost 150 minutes long. Here's what else you need to know.

• "Stranger Things 4" has been the most "supersized" season of the show yet, according to Netflix.
• The first part of season four already premiered, but the final two episodes are coming July 1.

Warning: Spoilers ahead for "Stranger Things" season four, part one.

Netflix switched up its typical formula for the newest season of "Stranger Things." The first seven episodes of "Stranger Things" season four premiered on May 27 — but episodes eight and nine won't arrive on Netflix until Friday, July 1.

The streaming giant has already revealed that episode eight is around one hour and 25 minutes long, while the ninth episode (which will be the season four finale) is almost two hours and 30 minutes long.

Co-creators Matt and Ross Duffer then plan to deliver a fifth and final season of "Stranger Things" in the coming years, though no date has been announced for that chapter yet.

As for what's in store, we hope to get more explanation about Vecna's origin at the Hawkins National Lab, and how he's connected to Eleven and all the previous monsters we've seen on the show.

'Stranger Things' star Noah Schnapp teased dark possibilities of how season 4 will end

If you're looking for hints about what might be packed into that extra-long finale, Will Byers' actor Noah Schnapp helpfully supplied Insider with three possible outcomes for the show during a recent interview.

"A main character dies," Schnapp said to kick off a round of "two truths and a lie" — a game where he makes three statements about the upcoming season of "Stranger Things" and leaves it up to fans to decide which one is the lie, and which two are really going to happen.

"There's an intense romance this season," Schnapp said for the second possible truth in the game.

He paused for a moment, trying hard to think of a good third possibility that fans can chew on.

"The Upside Down eats up Hawkins," he said at last. "Like, takes over the real world."

So which is the lie, and which statements are true?

Fans will have to wait until July 1 to see what's in store for the characters of "Stranger Things."
