For Kevin and Sophie.

Even for Randall and Beth.

And bubble baths and lava fries cant always fix everything.

You guys made some pretty big promises to each other, Miguel says.

But if I trust anyone to keep them, its the two of you.

And what should be a carefree occasion turns somber quickly when the latter couple announce they are divorcing.

Its flush the news shakes Jack and Rebecca on a level neither feels comfortable completely revealing.

At home, the always optimistic Jack declares that one should stay with their soulmate until they die.

Its not that simple, Rebecca says.

It is to me, Jack replies.

At the office the next day, Jack presses Miguel for answers.

Is he having an affair?

Why is the marriage ending?

But Miguel has no satisfactory answer for Jack.

And now to the present!

After waking from a dream in which his biological father dies (lousy fake-out,This Is Uswriters!

), Randall realizes that his eldest daughter, Tess, isnt in bed.

He and Beth find her downstairs playing chess with William.

Its heavy stuff for a tween, and Tess straightforwardness about Williams impending death unnerves Randall.

In a diner in the city, Kevin is trying to cajole an elderly couple out of their booth.

(And before their eggs have even arrived!)

He pleads his case to the couple: Its a special booth.

Its the booth he and his ex-wife sat in when they shared a kiss on their eighth-grade class trip.

Its the booth they sat in when Kevin decided he would move to L.A. and Sophie would stay behind.

Are you the Manny?

the woman finally asks.

And just in time, as Sophie comes storming in to tell Kevin to, essentially, screw himself.

After all, where they left off was Kevin cheating on her.

She flees to the subway with Kevin on her heels.

Shes really starting to come into her own at the weight-loss camp, perfecting her uppercuts and downward-facing dogs.

Until, that is, a distraction shows up.

And that distractions name is Toby.

and the body wash that makes Kate smell like Hawaii.

And hes been cleared for low-impact love-making.

But Toby doesnt take the process seriously.

He shows up in light-up sneakers and raps his drumsticks out of time with the choreography.

It was his final surprise.

Back at Randalls, tensions are running high.

He and Beth have hired a palliative care specialist.

Beth begins asking the specialist questions about handling grief, but Randall isnt ready for this discussion.

He begs off, saying he has to get to work, which isnt untrue.

And, can I just say, what an honest and long-time-coming plot line this is.

Later, we see him reaching for a glass of water, hand shaking.

Is it just stress?

Or is there a deeper issue?

Kevin awaits Sophie in their booth, with lava fries at the ready.

She finally appears but to what end?

And as for Kate, we leave her staring at Dukes cabin door.

Will she cheat on Toby?

Or will she finally tell Duke to leave her the hell alone?

For now, their parents are the ones to get the happy(ish) ending this episode.

Jack, determined to never take Rebecca for granted, hatches a romantic surprise.

He takes them to their first apartment, festooned with twinkling string lights and candles.

He pulls their ratty vows out of his pocket and they begin reading them to one another.

And then Rebecca tells him she wants to go on tour with her band.
