>>105816076>they thought the original set up didn't make sense
They could've easily worked a sensible setup. Give the road trip a destination, somewhere that Gwen really wants to go but can't. She's asked her parents but they're working and can't take her. Ben is talking about his roadtrip in class, and she overhears that he'll be passing right past that academy she's interested in applying to, or a celebrity's house that she's obsessed with. The gears start turning in her head. She goes to work on her parents, who have actually known the Tennyson's for years. Maybe her parents went to school with Ben's parents? Maybe Gwen's dad had a crush on Ben's mom back in the day, and while they drifted apart in life perhaps that influences the decision to let Gwen tag along?
