You’d better start stocking up on tissues now, because Tuesday’s Glee Season 3 finale, Episode 22: "Goodbye" is going to make you bawl your eyes out! We’re already starting to sniffle at the sight of the promo for next week’s episode — that is, we until Quinn (Dianna Agron) and Puck (Mark Salling) started making out. Yes, you didn’t imagine it. That actually just happened!

That one little promo holds so many great teasers and clues for what’s to come, and we don’t want to miss a moment of it! We’re breaking down the video: second by second, frame by frame in search of new clues. Take a look at what we’ve discovered.

Scene 1a: Tuesday, 9/8c.
Yes, you read that right. Next week’s Glee finale won’t air until an hour later than usual. (Hey, don’t be upset with us. Take it up with American Idol.)

Scene 1b: Will (Matthew Morrison) stands in the choir room.
He’s addressing the original New Directions. For one of the last times ever. Oh great, we’re starting to tear up already. And the promo is only at 0:01. This isn’t going to go well.

Will speaks “There’s only one thing left to do. Say goodbye.” Waterworks.

Scene 2a: Graduation is here!
Mercedes (Amber Riley) is dressed in a bright red gown. She gleefully tosses her graduation cap. Not too long, and she’ll be headed off to Los Angeles to pursue her dream of becoming a star! But what does that mean for Mercedes’ future in Glee Season 4? From what we’ve heard, Glee‘s “revolutionary” new show-within-a-show format is only going to include Ohio and New York City. That doesn’t make her chances of coming back seem very promising, no matter how much Amber Riley might suggest otherwise on Twitter.

Scene 2b: Finn and Puck perform in the choir room.
Based on the song spoilers for the episode, we’re betting this is Puck (Mark Salling) and Finn’s (Cory Monteith) rolicking performance of Bruce Springsteen’s “Glory Days.” Um, yee-haw?

Scene 2c: Burt Hummel (Mike O’Malley) is back!
We love every chance to see
Kurt’s (Chris Colfer) amazing papa, so having him in the Season 3 finale seems like an absolute must. But hold it: Is Burt performing that infamous Beyonce “Single Ladies” dance that Kurt so infamously wowed us with back at the very beginning of Glee Season 1? So. Many. Happy. Flashbacks.

Scene 3a: The graduating seniors emerge!
All dressed up in their caps and gowns, Glee’s seniors make their way down the hallway for one of the last times ever. But who is graduating, exactly? Last time we checked, Puck and Brittany’s (Heather Morris) futures still seemed very much up in the air. So will they walk at graduation?

Let’s see. We spot Rachel (Lea Michele), Mercedes, Mike (Harry Shum Jr.) and Quinn. That looks like Finn (Cory Monteith) and Santana (Naya Rivera) in the background. Then two more guys, as well. Yep there’s Puck all right.

Puckerman graduates! But what about Brit? She is nowhere in sight. Looks like Brittany might be repeating her senior year after all.

Scene 4a: “But as some say goodbye...”
Quinn gives Sue (Jane Lynch) a giant  hug. “I’m really going to miss you.” Sue starts to tear up. “I really don’t think that’s possible, but thank you.”

Scene 4b: “Others can’t let go.”
Wait a second. Hold everything. Puck and Quinn are making out! Holy Quick, is this actually happening? They’re in her bedroom, sitting on her bed. (Uh, guys: You do remember what happened the last time you were in a situation like this, right? You ended up making a baby.)

Whatever, they’re older and wiser now. We’re sure they’ll remember to use protection. We’re just thrilled that Glee is finally remembering the existence of this plotline. It’s about time.

Scene 4c: But what about Klaine?
Kurt and Blaine (Darren Criss) sit at a desk, their hands clasped together tightly. Kurt looks his boyfriend straight in the face. “I told you. I’m never saying goodbye to you.” That’s what we want to hear: Klaine forever!

Our only question is: What part of the episode does this scene air in? See, Chris Colfer recently shared that Kurt and Blaine’s relationship will “definitely zig” during the episode, but then zag again “at the end of the finale.” So as long as the “zig” is talk of a breakup, and this heartwarming scene is the final “zag,” then we’re totally good! But what if it’s not? We don’t want to even think of the alternative.

Scene 5a: The unforgettable Glee season finale.
Finn and Rachel make out on the graduation stage, right there in front of everybody. Hey, at least they didn’t make out onstage at Nationals like last year — because then THIS probably would not have happened.

Scene 5b: The graduating seniors toss their caps.
That confirms it: Rachel, Finn, Kurt, Santana, Puck, Mercedes, and Mike are all in the shot. Brittany is not. Our favorite Senior Class President didn’t make it to graduation. Sad. (But also GOOD, because we assume this means she’ll get to stick around Glee for another year. Season 4 without Brittany would have been a very sad thing to watch.)

Scene 5c: Now Rachel and Finn are crying!
Rachel sobs into Finn’s shoulder. “I love you so much.” Finn whispers back in her ear, “I’ll love you forever.” Sounds like a super sweet moment, right? Think again! We recognize that coat she’s wearing, and we know exactly what scene this is from. Rachel is about to hop on a train for New York City, and she’s leaving both Ohio and Finn behind!

So is that the end of the story? Is Finchel done for good? We wouldn’t jump straight to that conclusion, but Lea Michele did just recently reveal that Finn and Rachel’s love story would end on a cliffhanger this year. Gulp.
