Eric made a mad dash to the car, and hurried to climb into the front passenger seat. Once he was in he quickly grabbed Scrap so he couldn't jump out when the others tried to get in. He knew Scrap, he was small but he was protective. Smelling fear on Eric would make him want to try and protect him, usually he does that by charging and barking. Unless he was hit by a beam while they were inside, Eric seriously doubted that would work against the robot.
