ENTERTAINMENT WEEKLY: We finally get the long-awaited crossover!

What was it like for you to step back into Sabrina’s shoes and play her again?

It was a thrill.

I did quite literally, in theme with Rivervale, feel like I was in an alternate universe.

[Laughs] It was wonderful.

I enjoyed every minute of it.

It’s funny, she just like took over me the second that I started speaking.

It was the craziest thing.

I felt like no time had passed.

The best bike ride ever.

CHAOSended with Sabrina’s death, so do we get an explanation as to how she’s back?

What’s the biggest change in Sabrina?

How is she different?

She’s Sabrina the twentysomething witch, which makes for a wiser Sabrina.

That’s the most palpable difference.

We really just see Sabrina with Cheryl.

The big reveal of Sabrina happens and shortly thereafter she is spellcasting with Cheryl Blossom.

It’s very fun.

It’s definitely established as a dynamic duo.

Is she a better witch now that she’s older?

At this point, Rivervale could use some help.

She gets to be the hero of the story.

Did anything surprise you about this experience?

I was always itching to get over there.

Do we see Salem at all?

Not in this episode, but I hope that eventually we do.

So it sounds like there’s potential for more Sabrina in the future?

Yeah I think the door’s open.

I think the door is open, and that’s very exciting.
