During season two, it's heavily hinted that Clay is dealing with some sort of mental illness following Hannah's death. While it's not directly addressed this season, Dylan Minnette (the actor behind the character) told BuzzFeed News that he hopes the story will come up in future episodes. "It definitely is something that should be addressed because I think it's pretty clear that he definitely has some issues and he is struggling," he said. "It really takes a toll on him and almost takes him completely to the edge in this season."
