ENTERTAINMENT WEEKLY: You’ve said that you knew who the killer was going into this project.

I Know What You Did Last Summer

So the first question is: Why Margot?

SARA GOODMAN:This is my f—ed up brain.

I liked it being driven by love.

By being loved, by loving, by love, love, love.

And so everything is justified in that way.

I think that was what it was.

She had a nervous breakdown at USC and so she decided that that was the only solution.

But then you flip it to Margot, and it’s the same motivation, just a different twin.

If she knew, which obviously she did, then they killed the girl she loved.

And that’s the whole thing.

It was just flipped.

That is what the decision is.

It is a self-preservation and she’s going to be Lennon and that’s the end.

And all of her identity stuff is tied up in that.

There’s obviously places to go from there.

Does she love Margot?

I don’t know.

We’ll have to see.

I think Margot was equally shocked.

Ultimately it feels like you all delivered a very twisted love story.

This is better than any prom invitation.

This is the grand romantic gesture from Margot’s dreams."

And as messed up as that is, I think it speaks to her.

I think that those kinds of things we really went back and forth on.

Was she honest with Margot?

And then Margot was going to kill her anyway?

Those kinds of things.

Was she not honest with Dylan?

Who did she really reveal herself to and why?

And what the consequences of those things were.

That triangle and her identity.

Who does she want to be?

I feel like she needs a new name now.

But we never say her name at the end.

And I think also it makes you go, “Okay, what am I capable of?

Who do I want to be?”

Because, now she can be anyone, right?

She can reinvent herself.

That, very few people have a chance to do.

And at that age, you really still do.

You go to college and people don’t know you there.

So if there’s a season 2, is Riley (Ashley Moore) alive?

I guess you’d have to wait and see if there’s a season 2.

There’s a couple ways to go with it.

It definitely will reveal everything about the cult though.

Do you have a certain season arc in mind for this story?

Are you just seeing where it takes you in the hopes that you get to tell more of it?

When I originally did the Bible for season 1, I pitched a potential season 2 and 3.

They all took place in this world.

There’s no way, I hate that.

But I also feel like these two women are now stuck in a relationship for their survival.

I think a person is in prison for something he did not do.

And all he has is his faith at that point.

So there’s a lot of ways to go.
