We visited the set of time drama Frequency and grilled the cast on their Nightingale killer theories…

The cast does it, too.

Except for in person and probably at the scripts.

Does this change how Raimy and the rest of the police department engages with the case?

And I think thats unnerving because theyre hardly ever in that position.

Im like, I dont know.

They probably have something really clever up their sleeves.

Im just gonna follow my leads as Frank gets em.

The question of how the killer knows so much will start to become more of a focus.

Is he someone listening into Raimy and Franks conversations?

Smith said:

That was one thought I had!

We dont know why hes steps ahead of us yet.

That could be one explanation.

There could be a lot of them.

But somehow, he seems to always be right ahead of us.

Will Franks suspicions turn to the people around him?

Smith said definitely, adding:

Its becoming too obvious that things are getting tipped off.

We dont understand what it is or why, but Frank kinda almost loses his ally in a sense.

Mekhi Phifer on the Nightingale killer…

This is based on his own personal theories rather than inside information.

The actor added of his Nightingale hunch: With these scripts and this story, you never know.

It could go so many different ways.

Is there any chance the Nightingale killer could be Satch himself?

Phifer said:

That would be interesting.

He would have to be a hell of a sociopath.

It could be interesting.

I dont think theyre going that way.

But it could be interesting.

Takeaway: It could be interesting.

In the 2016 reality, hes killed already 22 women.

Wrapped them in rosary beads and all that stuff.

This case has affected his life from the time he was just a plain detective in 96 to 2016.

He has a lot of feelings that will come out about this Nightingale guy.

Why hes so passionate about catching this guy and having this task force be a helpful producer.

However, his character seems like a red herring when it comes to the Nightingale killer, no?

So Stan runs the undercover wing that Frank was a part of in 1996.

So Stan in 1996 has nothing to do with the Nightingale.

Stan in 2016 has a bigger scope.

Hes risen in the ranks so he does weigh in on the Nightingale.

Does Kelley have any theories about who the baddie might be?

I feel like my theories change week to week.

But I dont think its going down that path.

Stan was too easy, hes already sketchy, he has other stuff going on.

Hes too busy being weird in other ways…

I dont know man, Im at a loss.

Kelley said:

The secrets more fun, I think.

They keep us on our toes.

Its like a serial kind of book that we get to read and then act it out.

Its a lot of fun to get the new scripts.

Its a lot of fun.

Lenny Jacobson on the Nightingale killer… That would be cool, though.

Whoever the Nightingale killer is, can we c’mon have Gordo catch him or her?
