ENTERTAINMENT WEEKLY: You told meCaleb would be back.

We had to make the days work for Graham to come in when he can.

So with this new Haas, where did the idea come in to give Caleb a brother?

We ended up cutting it for time, but in our minds, they always existed.

We also wanted Shelby to have to continue to be tied to the Haas family in some way.

He auditioned for the pilot, and

Did he audition for Caleb?Not gonna say.

You cant put Hunter on a show where Graham existed and not have them play brothers.

Speaking of dirtying someone up, what can you tease about where Leons story is going?

Ultimately with the G20 stuff, we did reveal Leon to be a good and true person.

So who are those people?

This was the first episode with a single timeline.

What was the biggest challenge to that transition?The hardest thing was the energy.

The future [timeline] allowed us to sit with the characters more in the present.

It was tricky to discover the new rhythm.

Once we did, I think it just gets better and better.

Sasha is also a new character in the story.

We wanted to look at those checks and balances.

We knew we wanted her to interplay with Ryan, and shes with us for a long time.

That story is only going to get richer and wider, and it touches on everybody.
