All of us that knew Elliot knew that OSU wasn't far away enough. His boys could drive to Stillwater.
His father figure, not his father, tried to get him to go to Tennessee for that reason. PE was the leader of his crew, that was well known in Tulsa. As Cobra pointed out, PE was well known with TPD and was a main suspect in several serious crimes. I have known PE since he was in elementary school and playing in AAU tournaments. He was a nice kid but I think he at times suffers from bi polar issues. He can switch him mental state with the flip of a switch. I saw it too many times.
Hopefully Clark isn't the same.
