Before Colin could pull out his gun, the young detective was shot and killed instantly.

Mare eventually took down the shooter, but it was too late for Colin.

It was a tragic end to the life of the detective who’d really taken a liking to Mare.

EW spoke with Evan Peters about his time on the show and his character Colin Zabel’s death.

ENTERTAINMENT WEEKLY: What made you want to get involved in the series?

EVAN PETERS:I was sent the materials, and it said, “Kate Winslet as Mare.”

I jumped at the chance to work with Kate.

The material was very grounded.

I know you got to film in Pennsylvania, which feels so rare in Hollywood.

What did it add for you to actually get to be in Pennsylvania to do this?

Oh, it was everything.

It was so nice to be able to just walk outside and hear people speaking.

You get close contact with the actual people who are living there, and I think it’s everything.

I wish we could shoot always on location.

It’s funny because I actually think it’s the opposite.

I guess they’re both sort of helping each other out in that way.

Well, now that you say that, it is kind of both.

He just maybe on the outside can sometimes present as more optimistic.

And I think, even in her haste, she is dealing with a lot more.

Her stuff is just so much heavier than his.

But, at the end of the day, I think he has some demons.

Colin seemed so crushed!

[Laughs] Kate would always be like, “Aw, poor Zabes,” which is true.

He’s trying so hard to just be a great detective, and he’s not the best detective.

He’s kind of a tragic character in that way.

And then, of course, the ultimate tragedy: He dies.

I assume you knew going into this that he was going to die?

I did, yeah.

They gave me the first five [scripts], so I knew that he would die in five.

It feels so sad that he’s taken outjustas they’re about to get the bad guy.

Yeah, it is pretty sad.

It’s incredibly tragic.

We wanted to bring a little levity in with him.

And it just felt, when he dies, you want it to be shocking and tragic.

So we decided to make him a little bit more of a bumpkin, trying to figure it out.

He’s not the best detective.

You know, he’s good.

He gets the job done, but he’s not Mare.

Mare is an incredible detective.

But, it’s that arc of him finally getting better.

And I think at the end there, he does some really good detective work.

He at least got that.

The way you all shot that scene, I couldn’t immediately tell if he was dead.

Yeah, it was pretty shocking.

We played with time a little bit there and slowed it down.

But Colin is not a quick draw.

That is for sure.

He is not a quick draw.
