So, how worried should viewers be that Toby might not be married to Kate anymore?

Depends on what you want to worry about, Sullivan quips to EW.

I mean, its not going to be easy…. Did Fogelman hint to Sullivan about the resolution of this story?

There have been several hints, he says.

There were different options, actually.

When Dan said it to me, hes like, We could do this or we could do this.

He asked my opinion and I gave it.

And I am not 100-percent certain anyone knows.

Its like, Lets have him bring it in and well figure it out.

When I asked Dan about it, he was like, It could be a couple things.

It seems to be what hes good at.

Everyone seems happy hes out of the NICU, so thats good news, Sullivan says.

Theyre trying to navigate all kinds of new things.

The NICU story line, by the way, proved to contain Sullivans favorite scenes from season 3.

(Brown uses words like subversive and disruptive.)

When I read episode 1, I was like, Wait!

The opening of season 4 is going to be very surprising.
