Dash doesn't have a great relationship with his father, Gordon, who is divorced from Dash's mom and is now an active dater. It's implied from flashbacks in which Dash has dinners with Gordon that he feels out of place around his dad's myriad girlfriends, and those feelings come to a head in a later scene when Gordon antagonizes Dash by calling out that he's not into sports and would rather have his nose in a book.
Understandably, Gordon's harping on antiquated gender stereotypes is unsettling, and overall, the scene is pretty uncomfortable. It may be worth chatting with your children about the fact that people don't have to enjoy certain activities because of or based on their gender. Additionally, the scenes with Gordon could drudge up feelings of animosity in young viewers who may have a complicated relationship with a parent, but could ultimately open up an opportunity for talking as a family, if applicable.
