The Pearson family gets an unexpected visitor in the upcoming This Is Us season 5 episode 11. Titled "One Small Step," the story revolves around Nicky Pearson (Griffin Dunne), Jack Pearson's (Milo Ventimiglia) brother. There will be flashback scenes, which could bring more revelations to the family.

This Is Us season 5 episode 11 is going to be all about Nicky. This is a chance to learn more about why he decided to visit the Pearsons, given that he's already living on the other side of the country. He hasn't been with the family for a long time and it's interesting to see how he'll spend time with them.

The upcoming episode picks up where episode 10 left off, wherein someone knocked on the door. It was confirmed that "Uncle Nicky" is the unexpected guest and the Big Three, Randall Pearson (Sterling K. Brown), Kate Pearson (Chrissy Metz), and Kevin Person (Justin Hartley), were all surprised.

It can be noted that the current installment of romantic family drama is set during the pandemic, which means that it's difficult for characters to travel. But, writer Casey Johnson noted that Nicky had the COVID-19 vaccine that's why he's safe to visit the family.

The promo of This Is Us season 5 episode 11 featured Nicky's journey in order to get to the Pearson's doorstep, flashbacks during his time in Vietnam, as well as his relationship with Jack. In addition, the clip teased the return of Cassidy (Jennifer Morrison), who drives Nicky possibly to the airport.

At the end of the trailer, Kevin and Madison (Caitlin Thompson) couldn't believe that Nicky traveled just to visit their newborn twins. There'll be a lot of interesting stories coming here, with some believing that this unexpected visit brings more emotional moments for the Pearsons.

In fact, some fans shared their thoughts about Nicky's arrival in This Is Us season 5 episode 11. One fan on Reddit noted that he is back to serve as "a great example of forgiveness and self-forgiveness" for Kevin and Randall. After all, the two brothers need to work through their reconciliation.

Nicky has been with the family in the flash-forward scenes, hinting that he'll have more important roles as time goes by. He's also with Rebecca Pearson's (Mandy Moore) bedside, suggesting that he grew closer with his brother's wife later on in life.

This Is Us season 5 episode 11 airs on Tuesday, March 23, on NBC.
