Tension mounted as the hours ticked by.

Kevin tried to downplay his relapse, promising Zoe (Melanie Liburd) that he was already past it.

Ultimately, they reached a truce and promised to find a way to make their schedules work.

Kate named the baby Jack (what else?)

and alongside Toby made a plea to her fathers spirit to protect their newborn.

ENTERTAINMENT WEEKLY: Who should we be most worried about right now?

Or Zoey and Kevin?ISAAC APTAKER:Oh, man.

Everyone has to rank it for themselves, depending on which story line youre most invested in.

I think Im the most worried right now about, I would say, Randall and Beth.

Because its been simmering all season, and it finally goes into a head.

Are they just a writers room fave, or was that integrated advertising?

[Laughs] Bekah Brunstetter, who wrote the episode, is a playwright.

And we kind of turned this one over to her and let her do her thing.

Zoe is steeped in trust issues, and Kevin knows thats a trigger for her.

So whats her next move?

And so, they have some serious work to do.

So on the other hand, they could attempt to work through this and regain that trust.

But its definitely a rocky road ahead for them.

You cant let something like that simmer.

How worried she would be about Kates baby?

The babys name is Jack.

We all guessed that could be the only choice, in spite of what Kate said about waiting.

Of course shes going to name him Jack.

We even entertained Jackson and Jake and kind of similar, derivative names.

And it came down to, just, nope Kate would name her baby Jack.

Theres no way around it.

Kevin and Randall clearly have so many deep issues and resentments.

Namely, his relationship with Beth.

I have a brother, so many of our writers have brothers.

And it feels like those brother issues, that sort of core dynamic there, never really goes away.

Thats the fundamental dynamic between Kevin and Randall.

Even though theyre in a really good place, its still there.

Rebeccas memories of her final trip to the hospital with Jack are seared on her brain.

Has she ever told anyone this before?

Thats a chapter of their lives thats so hard to talk about.

As weve seen over the past three years.

Are Miguel and Rebecca definitely going to move?

What does that look like from here?Yeah, were excited about it.

Theyre planning on it!

So were really excited about telling a fun new chapter for them.

And also, I think it speaks to how far Rebecca and Kate have come in their relationship.

That this would be something thats even on the table for them.

Not only that, [she] and Randall have this very, very deep connection.

Tobys joke to Miguel felt a little cruel, and Beth also shut him down.

Miguel took it in stride for now, but how will he exact his revenge for this betrayal?

The Other Big 3 gotta stick together.

[Laughs] Yeah, Miguel is a bit of a punching bag for the family.

Jon Huertas innate charms are just unavoidable at a certain point.

We really found that people are starting to root for Miguel.

Seeing that, oh, he has these really sweet grandparent moments with the girls.

I think showing his relationship with his own family on Thanksgiving really helped.

And I think that theres been a big shift in terms of the tides turning for that character.

Miguel is a calming presence, from reassuring Madison [Caitlin Thompson] to having Tobys parents numbers.

And he really barely bristles at the kids rudeness to him.

Will Miguel ever just lose it?

Were planning on doing a lot more Miguel next year.

Exploring more of that period of right after Jacks death and his relationship with the family.

Why is everyone dumping on me all the time?

So it feels like somethings got to give.

And the question is: Who is going to be the one whos willing to bend in this relationship?
