This so random, but he does develop mental issues by end of this, he also already have amnesia cuz his brain injury, and he became suicidal by end of it but he do it self harm cuz the seme give him attention when he does it and he enjoy being treated harshly by him cuz he think it mean he care for him

Id like to see him get some infection or disease to see how he reacts.
A viral fever, muscle dysmorphia , a cancer or a heart attack that he can survive..
