Spoiler alert: This story contains plot details from Tuesdays episode ofThis Is Us, The Graduates.

Kate (Chrissy Metz) grandly graduated community college (remember?

she had returned to school?

), as Toby (Chris Sullivan) elevated the completion of eight credits into anevent.

R.I.P., Radio Shack Jack.

Her water broke, which means shes going to have it sooner than later.

How grave is this situation?ISAAC APTAKER:I think its like you said.

Ideally, she wouldve continued to grow this baby inside of her for a lot longer.

But it is a very nerve-racking situation.

Did it feel just like a realistic outcome to a high-risk pregnancy?Exactly.

So this felt like what would actually happen, which is always what we strive for.

This isnt something that were going to drag out.

How would you describe relations between the brothers-in-law in the next episode?Well, not great.

Id be pretty pissed off if I was Toby.

So I think theres definitely some repair that needs to happen between those guys.

Kate busted Kevin in his hotel room with empty liquor bottles.

Unable to drive her to the hospital, Kevin was seeing the consequences of his drinking.

Its so easy to forget that.

You want to say, Kevins being selfish.

How could he do this?

But this is a guy with a disease, and this is a guy in pain.

I think that moment really reminds you of that.

Rebecca bonds with Kate over how they really didnt want the next big moments of their lives to come.

[Laughs] Thats a relief, and I think so earned.

And this is kind of an extension of that.

How would you compare it to the long, intense rehab therapy scene from last season?

So that is what were doing here.

Do you feel like its as incendiary as that one?Oh, definitely.

Absolutely, if not more.

Its such a spectacular hour that Bekah Brunstetter wrote; she is a playwright.

We were so, so excited with how it came out.
