Trey (Jeff Pierre) has been through a lot.

What was your experience with that?

JEFF PIERRE:That was a whirlwind.

I read that script and I was, “What’s going on here?”

And I had a panic for a second because I mean, first of all, I love Lindsey.

She’s amazing, but I knew that meant something for me.

But shortly after that, [showrunner] Anna [Fricke] called me.

She said, “I know you just read it, but Trey’s fine.”

She didn’t even really get into anything.

She literally just said, “Trey is fine.”

So if she left, on a lot of shows, that’s it for Trey.

So, I’m glad I get to keep on doing this with them.

What has your experience been in the aftermath of that?

Because it feels to me like Trey has only become more ingrained in other parts of the show.

This is one of the things that I love the most about it.

But then I started having more with everybody and I just loved that.

I was actually on the farm and me and Captain James have a thing going on.

Just getting a chance to have different chemistry with everybody else.

And I feel like for Trey, he loves hard.

I feel like he’s part of the Walker family.

Given his skill set, it also just makes sense to have Trey around more!

But you know what?

He became a therapist on the show.

And I think that grew out his bond with the kids at the high school.

He was always that voice of reason.

He’s always there as a shoulder to lean on.

Can I be honest?

My first initial reaction, I screamed.

And I look at her: “Babe, I think I’m going to become a ranger.”

I’m happy for you.

Now I got to go put the baby to sleep."

[Laughs] But that’s how that went down.

It was so amazing in that moment.

And obviously he’s the perfect person to make it happen.

Something like this is huge.

It’s life changing for him.

And he’s been thinking about it.

Well, first he’s got to find his friend, then he can make his decision.

We need to save Walker.

A lot has happened from episode 1 to now.

He’s had a past where maybe he didn’t take things as seriously.

He was enjoying his time with Micki and his time and as a Marine.

But now, I think, he’s starting to really come into his own.

He’s forming these relationships with these people.

And I think his heart is growing even more.

Being surrounded by these people that he loves helps push him in the right direction.

So I think he’s on a good track now.
