Man, that one destroyed me every single time I read it.

So much so that he will put off the wedding.

He doesn’t care.

Carlos is first priority.

We learn that he does not sit down.

There are no leads.

This was premeditated, it was planned, someone meant to kill Carlos' father.

I think Carlos is forever changed.

So much so that he’s almost willing to kill.

He was going to pull the trigger.

Even when the heat gets turned down for the wedding, Gabriel’s death is still weighing on him.

Everyone’s loud, everyone’s laughing, and it’s a lot of fun.

But I personally had to remove myself because that’s not where Carlos would’ve been [mentally].

I desperately wanted to be there laughing and joking, but I couldn’t.

I sat separately from everybody to truly just have the focus.

Still, it’s a beautiful ceremony.

SILVA:The shot of us exchanging vows was one of the very last takes that we did.

It was an entire day of emotion.

I echo a lot of that.

Now, our son can live."

That was a really special moment for me.

It’s cool that she was there in some sort of capacity.

I think it was a really fascinating way to have one last gesture from Gwyn.

It was her wedding gift to the boys.

And Gina’s voice is just unbelievable.

It was pretty extraordinary.

RUBINSTEIN:It’s also so fitting that Tommy was the one to deliver that song.

Aside from the fact that Gina is a extremely talented storyteller, Tommy knows loss.

The song ends with Robert’s final moments.

TK doesn’t know about his uncle’s death yet.

How do you think that will play out in season 5?

RUBINSTEIN:I really hope they start next season on the next day.

I want to get into it.

I want to see him find out from Owen, right?

But when will that be?

I’m very interested to see what that secret does to Owen.

That’s probably going to F him up pretty good.

And where do you think Carlos will be when you return?

SILVA:Carlos has changed but how?

Is he still a police officer?

Has he abandoned the force, or is he in it more than ever?

Is he seeing a therapist?

Has he gone crazy?

Has he tried to take this matter into his own hands?

I’m excited to see how Carlos deals with grief.

SILVA:But I’m also excited to see who Carlos is as a husband.

Can we talk about this?"

RUBINSTEIN:I echo that!
