The fourth season begins with a special comedy where Jack and Rebecca decided to take the Big Three in the pool for a special day. At that time, Jack tries to meet Rebecca's parents and new characters may emerge along the way. Beth and Randall face a new path as they adapt to life in Philadelphia.
I have to admit that I thought the show would string us along for several episodes before revealing how these people were tied into the main story, but good on This Is Us - by the end of "Strangers" we know how they're initially connected.

The multiple story threads are becoming refreshed with new vines to follow, but what has not changed at all is the ability of "This Is Us" to be ever so moving.
This Is Us could have confused viewers by introducing three new families and allowing their stories to take up so much screen time. But at the end, it all came together beautifully.
After an uneven third season, season four is poised to be the moment where This Is Us either re-finds its feet or goes entirely off the rails. Now that's a mystery worth tuning in for.
