'Riverdale' Season 3 Will Have a Flashback Episode, Plus Everything Else We Learned From Comic-Con

Now that Comic-Con 2018 has come to a close, it’s time to take a step back and process everything we learned over the weekend about “Riverdale” Season 3.

First off, showrunner Roberto Aguirre-Sacasa promised at The CW series’ panel in Hall H Sunday that fans can expect a flashback episode early on in the upcoming season, in which the kids play their parents (so Lili Reinhart, who plays Betty, would be portraying her mom Alice, for example).

We can also look forward to another musical episode following Season 2’s “A Night to Remember,” in which the high schoolers put on a production of “Carrie: The Musical.” Casey Cott, who plays Kevin Keller, told us all about that episode right over here. But we can expect more music outside of the next musical episode, too. Kevin and Josie (Ashleigh Murray) will be living together in Season 3, now that their parents are dating. And while Murray said while that might cause some strain between the two friends (they have to fight over a bathroom like true siblings), we might just get a duet out of it, too.

Aguirre-Sacasa teased that Episode 3 will be an important one, as it will address the budding romance between Alice (Madchen Amick) and F.P. (Skeet Ulrich) and how that affects Betty and Jughead (Cole Sprouse)’s relationship… considering those are their parents. It sounds like the third episode will be centered around other relationships, too. Aguirre-Sacasa said that Reggie (), who now has a job at Veronica (Camila Mendes)’s speakeasy below Pop’s, finds an “unlikely” romance.

Aguirre-Sacasa also confirmed one thing that fans have been waiting for throughout both seasons: Jughead’s mom, Gladys, and sister Jellybean will be introduced around Epiosde 8 or 9 of Season 3. No word on who will play those characters yet, but we can’t wait to see how their arrival shakes things up for the Jones boys.

As for our dear Core Four? Archie (KJ Apa)’s arrest might put him and Ronnie on the rocks, but Bughead is strong as ever. Reinhart said that at the beginning of the season we’ll see Betty stepping into her role as the Serpent Queen. Speaking of Archie’s arrest — we also found out over the weekend that Penelope Ann Miller will play Ms. Wright, the prosecuting attorney in charge of Archie’s case.

You can watch the Season 3 sneak peek that was played in Hall H above.

“Riverdale” Season 3 premieres on The CW on Oct.10 at 8/7c.

15 Midseason TV Shows That Became Hits, From 'The Office' to 'Seinfeld' (Photos)

Not every show can make it into the fall primetime lineup -- and sometimes that's a good thing. Each year, networks have to find fresh programs to fill the midseason holes they face during long hiatuses or as cancellations creep up. And for shows like "Seinfeld," "The Office" and "Riverdale," being up against some easy competition during winter and summer lulls may have set them up to become fan favorites. Check out a sampling below to see some of the most beloved midseason replacements in TV history -- and some that are still airing.

1. "Seinfeld" -- Premiered July 5, 1989 on NBC One of the most famous sitcoms of all time debuted in the dead of summer, but that didn't stop the self-proclaimed "show about nothing" from becoming something.

NBC
2. "Happy Days" -- Premiered Jan. 15, 1974 on ABC Maybe a winter launch was what made the Fonz so cool in the first place.

ABC
3. "Buffy the Vampire Slayer" -- Premiered March 10, 1997 on The WB Viewers were introduced to Sunnydale High School's new vampire slayer well after the school year was already underway, but the shortened first season was enough of a hit for it to return for the fall semester.

20th Century Fox
4. "Grey's Anatomy" -- Premiered March 27, 2005 on ABC Shonda Rhimes began teaching us about medicine and love with the interns at Grey Sloan Memorial in the early spring of 2005, and hasn't stopped for 17 seasons and counting.

ABC
6. "Married... with Children" -- Premiered April 5, 1987 on Fox The Bundys began delighting viewers with their trademark brand of crass humor with a truncated first season in the late 1980s and kept going for 10 more.

Fox
7. "Malcolm in the Middle" -- Premiered Jan. 9, 2000 on Fox Life may be unfair, but the viewership this Frankie Muniz-led comedy saw for its winter debut on Fox was more than generous.
Fox
8. "The Simpsons" -- Dec. 17, 1989 on Fox The Matt Groening-created cartoon premiered just before Christmas and has since become the longest-running scripted primetime TV series in the U.S.

Fox
9. "The Office" -- Premiered March 24, 2005 on NBC Though the first six episodes of "The Office" may not be as universally-beloved as the rest of its nine-season run, we'll take a slow spring start over no Dunder Mifflin at all any day.
NBC
10. "Dawson's Creek" -- Premiered Jan. 20, 1998 on The WB The now-defunct network didn't wait for the end of winter before airing what would become one of the most famous primetime teen soap of all time.

CBS
14. "Dallas" -- Premiered April 2, 1978 Another CBS classic, nighttime drama "Dallas" took off in the midseason.
CBS
