WhenRiverdalereturns, the small town is in a state of chaos.
EW spoke with showrunner Roberto Aguirre-Sacasa about what to expect from the rest of season 5.
So I appreciate that.

Mark and Michael Consuelos in ‘Riverdale.'.The CW
I’m with you; time jumps can be very weird.
With all of the inmates running around, this first episode back is almost giving me Gotham City vibes.
It’s a classic criminals-running-amok-in-Riverdale kind of thing.
[Laughs] We love bringing those characters back.
Where did the idea for Penelope (Nathalie Boltt) creating her own ministry come from?
If you saw the HBO showPerry Masonthere was a similar character.
That was where the idea came from.
The idea of creating their own ministry felt somehow outlandish and yet very very Blossom-esque.
We saw Josie and the Pussycats in the latest trailer.
What can you say about their return?
I don’t want to spoil it but we’re getting to them sooner rather than later.
It’s wonderful; it was so great to have the girls back.
It’s one of our strongest episodes of the season.
Honestly, it’s all about Mark Consuelos.
Mark joined us in season 2 and he’s been such a terrific addition to the show.
He’s been completely up for being our big bad.
It’s a very off-the-beaten-path episode but we can’t wait for people to see it.
