Members of Canadian prog-rock power trio Rush.

Bad things come in threes, too.

First came Kevins calamity, as he descended into a vortex of alcohol and pills.

Then came Kates catastrophe, as she suffered a miscarriage right when she started embracing pregnant life.

And finally, on Tuesday night, came Randalls ridiculously rough ride.

How did Randall and Beth, in a panic over their missing daughter, handle this news?

The phrase Ill kill him!

ENTERTAINMENT WEEKLY: In this final episode of the Big Three trilogy, we dug deeper into Randall.

The bond between Jack and Randall deepens in this episode, culminating with that conversation at the memorial.

It seemed further proof that Randalls relationship with Jack will end as the least fraught of the Big Three.

And that does have a lot to do with the really beautiful relationship that he has with his father.

Theres not a lot of angst there, theres not a lot of drama there.

He mentioned that he hadnt even told Rebecca about what exactly happened in Vietnam.

Is there more to come on that, perhaps in a moment with Rebecca?

Its a very mature father-son moment.

NEXT PAGE: Will we see Deja again?

Is that mystery boy coming soon to the Pearsons?

This episode explores the idea of what is the best environment for Deja.

We probably spent six minutes with the character over our whole series so far.

They dont have very much to go off of.

But at the end of the day, they really are just hoping that they made the right choice.

As Linda says, this foster care business isnt an exact science.Exactly.

Even though he said, I know that.

Because it feels like he needed to hear that, even if he said he didnt.Of course.

Her performance is so incredible in this episode.

Have we seen the last of Deja?I cant say whether weve seen the last of Deja.

This could be it.

She could be back.

We then catch a glimpse of the young boy who was having trouble going through the foster care system.

And he might be the one that winds up with Beth and Randall for good.

She seemed welcoming of Deja, and was sad when she left.

Can you hint at why she is so unhappy?

Theres been so much upheaval in the house this last year with the arrival of William and Deja.

Kevin is so wrapped up within the drugs and misses whats going on with his sister.

Everyone is missing whats happening to the people right around them.

NEXT PAGE: Has Kevin bottomed out?

And how close are we now to Jacks death?

We have that perspective looking back on it.

For William, there was no way of knowing that.

Okay,nowhas Kevin bottomed out?

Will he come to terms with what he needs to?Yes.

Thats not where our show is going.

Randall and Kevin have been through some serious ups and downs over the years.

Its not exactly the perfect way to continue a happy brother relationship.

But addiction is an illness, and Kevin has really been suffering.

And then theres also the saving grace that Kevin did not know Tess was in that car.

She was running away from home, crouched down in the back seat.

Shes wrapped in her own thing.

Meanwhile, Randall has not only just found out about Kate but had Deja taken from him.

So theres always so much going on that people are missing the ball.

Lets talk about that final moment with the Pearsons.

But Randalls game of Pac-Man ends when the ghosts get him, and the screen reads Game Over.

Its a lovely family moment, but its also ominous it feels like the end is nigh for Jack.

How should we read that ending?Its definitely ominous.

So were really down to that one piece, which is Randall and his red-haired high school girlfriend.

And once we meet her, everything that weve seen is now in place.

Its safe to say that the time is closing in.

We were concerned with the amount of real estate we had with her.

And will we care when shes taken away?

That exceeded our wildest expectations.

In terms of the other question… that is trickier.
