Journal is very smart, but he can act pretty irrationally out of anger. Ever since his encounter with Mr. Hand, he slowly became workaholic, not caring much about his well-being. He hides any info about the topic. As of recent, his paranoia and stress had taken over due to his obsession with stopping Mr.Hand, turning him more bitter and irritable towards those who he had once good terms with. This resulted in him isolating from everyone and not listening to their concerns.
