Season three of Riverdale is underway and things have already gotten pretty crazy. There are floating babies, stolen dogs, and a really suspicious new character. On top of all of that, we're about to be taken back in time to the 90s when jean vests were cool and FP was rocking a letterman jacket instead of a Serpent jacket (weird, I know). That's right, the Riverdale flashback episode is upon us, and we can hardly wait. Don't know what we're talking about? Here's all the info on the season three episode, "The Midnight Club."

What can we expect from the episode?

Get excited, because "The Midnight Club" is about to be the craziest ep of Riverdale yet (and that's saying a lot because Riverdale can get super wacky). In a new clip from the episode, we see all of our favorite cast members (playing their parents) in school after hours getting ready to play the infamous "Griffins and Gargoyles." Madelaine Petsch leads the crew as a young Penelope (with braces and all). She explains the rules to the game, but Hermoine is unimpressed. "Not much of a party," she says. Luckily, Hiram has a solution, "fizzle rocks," which kind of look like the beta version of jingle jangle, the drug that took over Riverdale last season.

The fun doesn't end there. In another clip we see the teens as they start tripping on the fizzle rocks and form a band called "The Fred Heads." The teens run rampant through the school. Everyone seems to be having a great time except for the young Alice Cooper who, despite her tough exterior, doesn't seem down to do drugs with the rest of her friends.

This night will no doubt have consequences on the town that will last for decades, and we can't wait to see how the rest of the episode plays out!

Some things were different back then... Others, not so much... This Wednesday’s #Riverdale is an unmissable blast from the past. Teen FP and Teen Fred streaking, because why not? 🔥🎲🐍🏆💥☠️ pic.twitter.com/FK1LJFKxdr — RobertoAguirreSacasa (@WriterRAS) November 5, 2018

Yes, in several obvious ways, but the most important one is that we'll get to see Young FP and Young Fred streaking. S-T-R-E-A-K-I-N-G. Christmas is coming early, everyone.

Aguirre-Sacasa tweeted a super sexy pic of Cole Sprouse and KJ Apa playing their father characters as teens, and the heavens opened up and angels sang sweet hallelujahs.

Who's playing the parents?

For the episode, the younger cast members will be portraying their TV parents in high school. That means Lili Reinhart will portray a young Alice Cooper, KJ Apa will be Fred Andrews, etc. The cast looks amazing dressed in 90s fashion, playing their parents. In fact, KJ even went brunette for the episode and it looks great.

In addition to the normal cast, Trevor Stines, who you may recognize as the late Jason Blossom, will return as his dead father. Mark Consuelos' son, Michael, was fittingly chosen to play a young Hiram Lodge in the episode. The first image of his portrayal is here and the resemblance is uncanny, as expected.

From the photos that we have of the episode, it looks like relationships were just as complicated 30 years ago at Riverdale High as they are now. We've already seen shots of FP Jones seemingly flirting with Hermione Lodge and Fred Andrews hitting it off with Alice Cooper. Those are two relationships we've never explored on present-day Riverdale.

Plus, it's really hard to get past the fact that it's not Veronica and Jughead or Archie and Betty flirting, but their parents (I don't even know if that's better or worse)!

When is it Airing?

According to IMDB, "The Midnight Club" will air on November 7th as the fourth episode in the season. That means there will not be a new episode on Halloween and we'll have to wait in anticipation for one week longer.

Why are they doing it?

Because it's going to be so amazing to see the cast play their parents, duh! OK, but besides that, the episode actually fits really well into the storyline. "We learn learn about a really dark secret that the parents have been keeping since they were in high school," said Riverdale's producer, Roberto Aguirre-Sacasa about the episode.

Those caught up on season three will know that there's a game, Griffins and Gargoyles, that's taking control of Riverdale. It has already either directly or indirectly killed two students and who knows what other havoc the Gargoyle King will wreak on the town.

In episode two, Hermione gathers the adults in her office for the inaugural meeting of the Worst Parents Ever Club. Kidding, it's to discuss a vow they made in high school. While she doesn't mention exactly what she's talking about, she references Dilton Doiley, who was found dead with blue lips. This information seems to really resonate with the group, who all flash concerned looks when they hear the news.

Hermione is nervous that Dilton's scout, found by Jughead and Betty earlier in the episode, will start talking and it may lead back to the adults and "the secret that [they] buried all those years ago."

Tom Keller chimes in at this point, saying, "We made a pact to never revisit that night. Not to mention it. Not to even think about it." But Hemione won't have it. "We might not have that luxury Tom," she says. "Not if it's happening again. Not if it's our children. All our children, they're in danger."

The scene is very spooky and even more vague. But we can deduce that they're discussing Griffins and Gargoyles. Dilton took a combination of cyanide and some blue Kool-Aide-like beverage, which is what ultimately killed him. While we don't yet know the specifics, we know that his death, along with Ben Button's, had something to do with the game. Obviously, the parents got involved in the game back when they were in high school and things didn't end well. Now, we will get a glimpse into what happened and hopefully learn more about the threat which present-day Riverdale is currently facing.

What's the inspiration behind it?

The episode is inspired by the hit 80s movie, The Breakfast Club, which starred none other than Molly Ringwald AKA Mary Andrews. Anthony Michael Hall, who played Brian, the nerd, in the movie, will join the cast as Principal Featherhead in the episode.

How long have they been planning this?

Aguirre-Sacasa has actually been wanting to do a throwback episode for a while. "We’ve been teasing this for years, going back to Season 1," he told Deadline. "I call this the 'Lili Reinhart Memorial episode' because she’s been wanting to do a flashback episode for years."
