Who Is Jughead's Grandpa On 'Riverdale'? Forsythe Pendleton Jones Is A Mystery

There is about to be a new Jones man stirring up trouble in Riverdale. Jughead's grandfather has come up in conversation a few times so far in Riverdale Season 4, and it has become pretty clear he is a big piece of the puzzle of what's going on at the mysterious Stonewall Prep. Now, The CW has confirmed when Forsythe Pendleton Jones I will finally be making his appearance, and the upcoming episode promises to reveal who Jughead's grandpa on Riverdale really is.

Spoiler alert: This post contains spoilers up to Riverdale Season 4, Episode 7, "The Ice Storm." Things at Stonewall have been getting super weird for Jughead, and it seems like it may all be connected to his lineage. In recent episodes, Jughead discovered his grandpa was the original author of the Baxter Brothers books; however, after Forsythe Jones I left Stonewall for mysterious reasons, Mr. DuPont took all the credit for writing the novel.

The CW confirmed Jughead's grandpa will finally make his appearance in Season 4, Episode 9, which is titled "Tangerine" and scheduled to air on Wednesday, Dec. 11. The episode synopsis reveals Jughead will search for his grandpa, who will be played by Timothy Webber.

After declaring war on Hiram, Veronica enlists a secret weapon against her father — her Abuelita (guest star Ana Mercedes). Archie and FP team up to take Dodger down for good, while Betty and Charles investigate a series of strange attacks aimed at Betty. Elsewhere, Jughead's search for his grandpa, Forsythe Pendleton Jones I (guest star Timothy Webber), leads to more questions than answers, while Cheryl finally makes peace with the past that's been haunting her.

Most recently, Webber has had featured roles in Once Upon a Time, A Series of Unfortunate Events, Loudermilk, and Apple TV+'s new series See.

Aside from introducing Jughead's grandpa, "Tangerine" also promises to shake up Archie, Veronica, and Betty's respective storylines as well. As the synopsis teases, Archie will team up with F.P. to finally take down Dodger, who recently slipped out of the hospital with some help from his family. And fans will get to see yet another estranged Lodge, as Veronica brings her grandmother into her war with Hiram. But what promises to be the most twisted plotline of all is Betty and Charles growing even closer as they investigate a dangerous new case... meaning Betty likely still has no idea Charles is secretly working with Chic.

Before "Tangerine" airs on Dec. 11, Riverdale's episode "In Treatment" will premiere on The CW on Wednesday, Dec. 4. The episode will center on each of the main high schoolers' meetings with a guidance counselor to discuss their futures after Riverdale High, so fans will definitely not want to miss out on the drama that will likely come with that.
