Earlier Lea drove a gray SUV car with Shaun as a passenger but when they go on their road trip Shaun points to a red SUV car in the parking lot and says it is Lea's car.
Shaun supposedly lives on the third floor of his apartment building, but he appears to have a sliding door in the back that goes out to what looks like a patio. Maybe it's supposed to be a terrace, but how would his neighbor get to that door unless it was on the ground floor? This has happened in the shows with his new neighbor, the one who replaced Lea.
