Riverdale
Riverdale returns with season 2 on CW in October Riverdale/CW

Although Jason Blossom's murderer – who turned out to be his own father Clifford – was revealed, the finale episode of Riverdale's first season didn't end well for the three teens – Archie, Jughead and Cheryl. All of them will be dealing with "daddy issues" when the CW show returns with a new season this fall.

Archie is faced with the heartbreaking possibility of losing Fred while Jughead seems to be embracing his father's old way as he accepts the Southside Serpent's jacket. As for Chloe, her whole world came crashing down on 11 May's episode –The Sweet Hereafter – after losing her father and brother.

The cliffhanger finale indeed left several unanswered questions like, who shot Fred Andrews? Is Cheryl plotting revenge? And is there a war brewing in the town?

Here's what fans can expect when Riverdale season 2 returns on CW:

"Jughead is going to be placed in the center of two worlds; he's got his foot on the North Side and his foot on the South Side, and that places him in a kind of dilemma," Jughead actor Cole Sprouse teased. "[With] Archie and Jughead, we're going to be discussing social circumstances that force a person to do bad [things]. ... That's really going to be Jughead's dilemma this next season."

Cheryl is meaner and colder – what's her game?

Madelaine Petsch, who plays Cheryl Blossom, confirmed that her character is not going to join the sad breakfast club instead she's even meaner and even colder in season 2 of Riverdale.

"Veronica wants Cheryl to become a part of the gang, and Cheryl wants so badly to become a part of the gang," Petsch told TV Line, "but she's so egotistical and there's so much going on in her head that she doesn't do it."
