John B told him once that if he kept going like this he was gonna end up just like his dad (reciting something JJ had said to John B earlier on) and JJ reacted angrily, but he seems to be aware of the fact that he was in fact becoming more and more like his father. However, when Deputy Plumb told him that he was going to end up in jail one day because it's in his blood, it seemed to affect him. JJ normally acts all carefree and like he doesn't care about other people's opinion. He still wishes that his father would love him or be proud of him though. However, when he is with his dad, he becomes more quiet and withdrawn and doesn't try to fight him because he is scared of him, until he finally spoke up for himself and fought back one day. JJ always has a snarky comment or a witty remark. He is self-aware of his dangerous, violent and criminal behavior, like his very unsafe driving. He often provokes others, knowing the consequences, just for fun. He's known at the police station for things like that. He is often seen smoking weed or drinking. He even stole the ambulance from his cousin. He steals without batting an eye, like he stole a gun and kept it.

He has a good heart and normally puts his friends - or his family as he calls them - first. JJ is also very protective of his friends and can't take their fighting. He is reckless and energetic and can't seem to hold still for even a few minutes as he always has something to say. When Shoupe told the remaining Pogues that Sarah and John B most likely died in the storm, JJ got angry and threatened to kill him, even though he would probably never really do that. JJ is someone who doesn't hesitate to get violent and hurt others, his threats often become true. JJ is also the one that the Pogues are usually worried about when they get into trouble, because all of them know that he might get them into even more trouble by his dangerous actions. His loyalty is shown when he took the fault for Pope even though he knew that his dad would hit him again for this. JJ likes to cover up his emotions and pain with humor. He might be like this because he doesn't know any different from home. He gets into fights a lot and his first solution is usually to fight others. The first plan JJ comes up with is usually something that includes violence, like killing other people or threatening them. JJ also seems to have anger issues, as he often has violent outbursts for seemingly no reason. When he wants something, there is not a lot that can stop him from getting it. He gets himself and others in trouble a lot. He is also not very good with emotions and comforting others, but he is loyal to his friends and would do anything for them. He always speaks his mind, even if it is hurtful. He tends to be irresponsible and doesn't think about the consequences of his actions. JJ is usually the life of the party and a trouble-maker.

He is John B's oldest friend, having been friends with him since the third grade. His father often has frequent violent outbursts which has led to JJ's own struggles with violent behavior. His mother never appears in Season 1 but his father does mention that she left, blaming JJ for it. He also physically and mentally abuses JJ. He can't hold down a legitimate job and it is insinuated that he is part of nefarious deals around the OBX. His father is an alcoholic and a drug addict - We see him leaving Barry's place before we know that he's JJ's father.
