I was so excited/shocked/terrified."

“It was a big surprise when I first got to set and I realized that nobody else knew.

I just assumed that other people would know, but nobody knew.”

ADINA VERSON:No, I did not.

The crew members were all like, “Oh my gosh, wait a minute.

Is it Poppy?”

So then they were all in on the secret.

Selena and Martin didn’t know until they got the script for episode 10.

That scene was filmed separately.

I actually don’t think that Jayne Houdyshell, who plays Bunny, even knew.

Wow, this is so much more cloak-and-dagger than I thought.

Even behind the scenes!

Yeah, it was really fun to have that secret alongside Poppy.

[Laughs] I’m excited for them to see it.

It’s been weird, and kind of humbling, being like, “Will people be mad?”

She’s really smart, but her Achilles heel is that she needs recognition.

She’s like this little soft, wounded creature and I have a lot of empathy for her.

What was it like playing the moments when Poppy finally gets to reveal that she’s actually Beckyandthe killer?

It’s just sad to me that there’s so much unkindness towards Poppy.

I ended up just doing a bunch of different things and then they edited it really beautifully.

That would’ve been a bad choice.

And people were really surprised that Poppy was the killer!

I think that maybe some of the actors didn’t get the full script …

I don’t know why, but people were still confused while we were shooting it.

They were like, “Oh, it’s Alice.”

I was like, “Wait, no, have you read the next few pages?”

Poppy got to come be revealed in front of the whole cast just doing the scene.

Could we see Poppy again, like how Amy Ryan’s season 1 killer Jan returned this season?

Nothing has been confirmed.

Maybe Poppy/Becky still works with Cinda on the next season of their podcast but while she is behind bars.

That would be amazing.

Maybe there’s some prison scandal and Poppy has the inside scoop on it.
