Better yet, what was it like to film such a somber scene with Ventimiglia looming nearby?

And because we’re asking questions, is there any chance of another addition to the Pearson family?

Below, Mandy Moore offers some insight to EW about “Three Sentences.”

I watched it, and I was crying.

I’m like, Dan, people are going to lose their s!'

He’s like, Really?'

I’m like, Yes!'"…

I was so affected.

She has this guttural scream while she’s in this therapy.

I was just like, “Ooof.

Cue the tears.'

It was really overwhelming.

The connection of the death of her father plays abigpart in her issues in life.”

It could be two seasons from now when we actually shoot a real scene around this.

I need to remember where I am and what I’m doing.'

On Ventimiglia being present at the shoot:“He was very respectful.

(Laughs) Sensing him there was weird.

It was almost as if he was a ghost just sort of watching us and observing this scene.

It was pretty heavy.”

On what those final images mean for the story:“I’m not sure people arepreparedfor this.

I hope it at least satiates some of their need to knowwhat,when,how,whywith Jack.

As Dan said: This is a line in the sand.

This is a critical juncture in the life of this family.

In the course of this family’s trajectory, everything is before Jack and after Jack.

This is that moment of utter loss and devastation and a family drowning in grief and sorrow.

I mean, I can’t even imagine….

It’s beyond tragic.”

We need to buckle down and take care of them to the best of our ability.

We can’t have this baby.

We can’t even take care of a dog.

We have three kids that are on the cusp of being young adults.

What are we even thinking?…

I love that idea.

And I wonder how that factors in somewhere down the road.

Or maybe there’s a kid that’s in the army.

Is there another kid?

I don’t think so.

I feel like we would’ve known about that.

And they deserve to have a dog.

Hopefully said dog will make its appearance in season 2."
