Courtney is in this extremely weird place where she's too young to really hang out with Will, Jeremy, John, Darius etc etc but she's also too old to be besties with Riley, Maddie, Bobbie, etc. God, middle school age is the worst. (She's close to turning 11, which should translate roughly to her going off to 6th grade this fall.)
I think it's smart for Mark to bring Courtney in because he can pull in "bridge" characters through her. By that I mean he can bring in characters that are the same age as Courtney. It will be useful to have that whenever Mark decides that he's finally had enough of the Elder Millennial characters (so Matt, Wade, Will, Jeremy, Travis, etc) but isn't ready yet to have Riley and Maddie be 15 years old.
Always nice to see the Boston crew. I wonder what day school Wade insisted on Maddie and Riley attending. (They're turning 6, so they should be getting ready for grade school.)
