Finn’s Explanation

Garry's eyes seemed to be focused on looking ahead, where the car in front of him was a coordinated car that he guessed must be headed to where Cale and Sue were.

Until ...

"What the hell!!" Garry shouted quite excitedly when the four cars that had been walking hand in hand suddenly dispersed just like that when there was a crossroads.

Garry quickly swerved, trying to follow one of the cars, hoping he was following the right one.

"Ugh... did they realize that I was following them, and for that reason, they trick me now?" Garry mumbled, who was still trying to follow one of the cars he had chased.

To be honest, the longer he drove following the car in front of him, the less sure he was that the car in front of him would lead to where Cale and Sue were.
