How does Barry feel

Barry was the driver of the car that hit and killed David Gregg. He is especially concerned about getting caught because he was 18, an adult at the time of the accident. It was Barry's decision not to stop or go back to help, and he insisted they all create a pact not to tell what happened. He dates Helen among others and is physically attacked - shot by someone who tells him on the phone that he has pictures of what happened last summer.
