NBC's This Is Us is one of TV's most popular shows and a big change is coming for two of it's main characters in when Season 4 kicks off on Sept. 24.

At the end of Season 3, Randall and Beth (played by Sterling K. Brown and Susan Kelechi Watson) had decided to move from New Jersey to Philadelphia.  TVLine.com interviewed Brown and Watson and found out that the TV couple start off the season "in a good place.”

The actors told TVLine.com that the same can't be said for their TV daughters, Tess, Annie and Deja.  As expected, a move like this can be more difficult for children than adults.  Watson explains that the kids face challenges like, "Going to a new school" and "meeting new people."  She also says that the family has moved into a smaller home, which will cause it's own set of new challenges.

This Is Us is nominated for an Emmy for Outstanding Drama Series.  In addition, Brown is nominated for Outstanding Lead Actor in a Drama Series.  Winners will be announced on Sept. 22.

A website called tvseriesfinale.com says that viewership for Season 3 of This Is Us was between 7-10.5 million weekly viewers.
