Theres just this general feeling of not quite being deserving of this big extraordinary life hes lived.

What was the biggest challenge in creating Kevins addiction arc?

It was both of those things.

It does have such that TV trope of [hums dramatically] Dun-dun-dun to it.

Of course his drug of choice would be painkillers.

In terms of that, its hard to feel for this handsome movie-star guy.

I dont feel that way because of Justins performance.

He brings out the pain and humanizes Kevin so much.

And I think tonights a real showcase for that.

All he wants is for someone to say, You dont deserve this.

And everyone in that room just takes it as, Oh, the movie star is being humble!

Hes throwing the praise on to these other people.

And they love him even more.

And that scene on the football field, which is my favorite scene in the episode, K.J.

That was something we knew was coming and we knew we wanted it in this episode.

And then it was K.J.

Lets start with the first, in the hospital.

How hard was it for Kevin to process the image of Jack praying for strength?

This is not the man that I know.

I dont think its magically fixed in that moment.

Young Kevin always felt neglected, that Jack and Rebeccas attention was on Randall or even Kate.

Are they more excited because theyre living vicariously through me and have bragging rights?

Or is it proud of me no matter what because Im their kid?

Plus: Is there any hope for Sophie and Kevin?

Alexandra Breckenridge, who was made a series regular this season, is pregnant in real life.

How might that impact how you are telling that story in the second half of the season?

How much will we get to see her?Shes due very, very soon.

Weve been able to work around it, so nothings off the table with her.

Lets go to the powerhouse moment on Charlottes lawn near the end of the episode.

And we had a couple of different versions of how he actually would come to lose the necklace.

So we knew when he lost that, that would be his Oh my god, his low point.

How will he react to this news?

I mean, weve seen how much hes hurt Sophie.

But I dont think Kevin even realizes how disconnected hes been from his family and especially his twin sister.

Can you hint at how Kate react to this tragedy of losing a child?Thats next weeks episode.

[Its] a special hour of television.

How will that impact her?Thats really tough.

She was really, really reluctant to tell anyone.

She didnt want to let herself get excited.

She was being as protective as possible in terms of getting invested in this pregnancy.

And Toby was the one who broke her open and said, No, this is exciting.

We have to believe in this, and we have to get psyched about it.

How could you get me excited and now its gone?

And we find out this information in someone elses story line.

So, it was important to us to connect the episodes.
