The beginning of the present-day story is set to the episode-eponymous song “Guitar Man.”
Let’s dive in.
However, unlike his siblings, he doesn’t yet know how to swim.

Jack (Milo Ventimiglia) gets in the pool to take a stab at help him finally learn.
After a while, Kevin impatiently asks again about going to the diving board.
Frustrated, Kevin storms off.
Rebecca finds him sulking.
Kevin says he’s not like his father, but Rebecca insists he is.
And that mindset never faded.
(A nod to Kate’s quiet strength, as we’ve seen Rebecca do in recent episodes).
He ponders quitting acting to become a builder like Jack, since Jack was so solid.
Again, Kevin’s thinking of himself as not enough inferior to his siblings and especially his father.
Then, Kevin prepares to head to the cabin with the twins.
He rudely demands an explanation from Cassidy, who accepted his job offer of overseeing the construction.
The foundation was poured wrong and needs to be redone.
At dinner, Kevin and Cassidy make amends.
Then they, Matty, Nicky, and Edie have a joyous dinner and game of Monopoly.
That night, Cassidy disappears for a drive and gets into a car crash.
However, the doctor says Cassidy was fully sober and had even refused pain medicine, for her sobriety.
Kevin is relieved to hear that, and that she only suffered a fracture and broken arm.
Nicky says to help Cassidy, Kevin needs to just be there, and nothing more.
So, Kevin spends the night.
Kevin then visits Cassidy’s bedside.
He vows to only sit and not ask questions.
The weight of those thoughts is heaviest when her son leaves her to return to his dad.
Nicky gives Cassidy the name of a readjustment counselor who helped him.
The flight home with the twins goes significantly better for Kevin.
When the flight attendant says Kevin’s good, he says he’s getting there.
And like Kate that night in the empty pool, he will get where he wants in time.
