It goes without saying that Riverdale Season 4 has been bonkers thus far. 

With Halloween around the corner, the series will continue to get crazier. 

On Riverdale Season 4 Episode 4, airing October 30 on The CW, the teenagers will, once again, find their lives on the line.

The official trailer for the special installment has Betty front and center as she's seemingly confronted by faces from the past. 

She also finds herself being tormented over the telephone, so there's that. The official synopsis teases that her past will come back to haunt her. 

Yes, we're talking about the Black Hood, but will these be hallucinations from the teenager, or something more sinister?

As for Jughead, he will be back at Stonewall Prep with his own mission to solve. He gets wind of a bunch of former students who disappeared. 

It was obvious there was more to that school than we were being led to believe. It all seemed way too perfect, right?

Jughead has a knack for finding himself in trouble, and with Moose leaving the school, it's likely he will be all alone unless he can get some allies. 

As for Archie, he'll be continuing his plight to make the gym a community center for the teens of Riverdale. 

However, things take a turn when some unwanted visitors crash the party. What lengths will the red-head go to to keep everyone safe?

Veronica will find herself in more trouble, and it's hard not to imagine it having something to do with the big bag of cash Mad Dog wanted her to clean through her nightclub. 

Then there's Cheryl and Toni. They are stunned to realize that there's a haunting at Thistlehouse. 

Could it be the spirit of Jason or something else entirely?

Only time will tell.

For now, watch the official trailer below.
