After a nearly two-month hiatus,This Is Usreturned tonight with the fifth episode of the season.

But there’s an adjacent theme, too: “the road not taken.”

The episode reveals a pivotal moment in each Pearson’s past that could have completely changed their lives.

Let’s see what those roads are/were, starting with Kate.

He wonders why she didn’t tell him sooner, but doesn’t judge her or get particularly mad.

In a flashback, before Kate’s abortion, she visits Marc.

Still, Kate doesn’t immediately leave.

Marc turns on the television.

When he scoffs at the movieAirplane!

a Pearson family favorite Kate fondly remembers watching with her father that’s the final straw.

While Marc’s distracted, she disappears without telling him about the baby.

It’s quickly made clear, in their interaction, that Marc doesn’t have much going for him.

Kate asks him what he remembers of their relationship.

He brushes off “intense” moments as normal kid stuff.

Kate notes she was a kid, but he was 24 years old.

She calls him out for taking advantage of her youth and vulnerability, and for treating her so terribly.

She “gives back the disease” he gave her, and leaves.

Kate beams with relief and pride on the ride home, and thanks Toby for his support.

He’s the cure to the pain she’s experienced in her life.

Proving that, later that night, she and Toby watchAirplane!and Toby loves it.

Kevin is hesitant to go because of the incoming twins, but Madison supportively insists.

The two share a kiss.

That’s not the life she envisioned.

I am FURIOUS she’s implying he must choose between career and family.

Can television shows cancel this trope?

The “couple” share the world’s most awkward half-kiss goodbye.

Will they continue to force it?

Actually fall in love?

Or agree to just co-parent?

If the latter, will Sophie return?

Randall advises him that going to L.A. could ruin his relationship with Sophie.

Kevin dismisses the concern.

But is it, if he doesn’t love Madison like he loved Sophie?

Kevin’s road not taken is staying in New York with Sophie.

What home will the road he’s on now take him to?

Kevin expresses regret over Randall having had to face his identity struggles alone throughout their childhood.

The abrupt goodbye makes Kevin think Randall is still mad.

Hai says she died of breast cancer in 2015.

Shaken, Randall leaves work early.

So, he should want to take the risk and see what Hai has to say.

That night, Randall is deliberating when Kevin calls.

Randall ends his conversation with Kevin and calls Hai with Beth at his side.

After an awkward introduction, Randall asks Hai if William lied about Laurel’s death.

Hai thinks William told Randall what he believed was the truth.

Beth and Randall decide to go to New Orleans to meet Hai to learn more about Laurel.

See you next week for whatever wild rides are in store for Randall and his siblings!
