In the past, Jack, Kevin and Randall go on a camping trip, leaving Rebecca and Kate to have a girl’s day to themselves. However, while the boys are away, the nursing home where Jack’s father Stanley is staying called to tell Jack his father is dying. That means Rebecca will meet her father-in-law on his death bed.

Meanwhile in the present, Kevin invites Randall to a charity gala. Randall takes Deja to the gala, since it’s the first time Deja is actually excited to do something.

In Los Angeles, Kate tells Toby about her pregnancy and she recalls her special day with her mother. Thankfully, Toby is just as excited about the news as she is.

In the end of the episode, we were dealt a huge twist: Jack has a brother named Nick. We saw the two boys waiting in a truck for their father. Then, we saw the older Jack looking through his files. He stared at a picture of Nick during their service in the Vietnam War. It looks like the brother might have died, but there was nothing to confirm that. It appears that Jack had his brother’s dog tags in the box.

We still don’t know if the brother died. Some think that Jack has the box because Nick is deceased.
