Hermione might visit Harry. She would probably be worried about him living alone and bring him some books she thought he'd like or some new potions she'd been working on.
One possible plot could be that Harry, after years of dealing with the chaos in the wizarding world, decides to live by himself to find inner peace. He might choose a secluded place, like a small cottage deep in the Forbidden Forest. He spends his days studying ancient magic that he never had time for before, and perhaps he starts to document his past adventures in a detailed journal.
Well, he might manage his daily life by relying on magic for basic tasks like cooking. He could use spells to clean his place and keep it tidy. Maybe he'd also use magic to grow some food in his small garden if he has one.
Perhaps he's dealing with some sort of trauma. For example, after the many battles he's been through, like the fight against Voldemort, he may be suffering from post - traumatic stress disorder. To cope with this, he isolates himself from others as he doesn't want to burden them or he's just too caught up in his own dark thoughts.
If he stabs himself in a non - vital area, he might survive but be severely weakened. This could lead to him having to rely on his friends more for protection and support, changing the dynamics of their relationships.
Another reason could be his sense of responsibility for the whole wizarding world. Since he's the 'Chosen One', he might blame himself for every setback in the fight against Voldemort. He may think that any harm that comes to the wizarding community is due to his own inadequacies in leading the fight or in not being powerful enough quickly enough.
No. The Harry Potter series is aimed at a wide range of audiences, including children and young adults. Such a concept is inappropriate and goes against the values of the original story which promotes friendship, courage, and the fight against evil.
In many fanfictions, Snape's sacrifice for Harry is often explored in great emotional depth. One common aspect is how his love for Lily Potter extended to protecting Harry. His self - sacrifice is shown as a redemptive act, finally revealing his true nature to Harry, which was full of love and loyalty all along.
Hermione would be a likely helper. She's always full of knowledge. She could research about simulacrums in the library and find some old spells or precautions that Harry should take while creating or handling it.
It could be due to the trauma he has experienced. Losing friends and facing Voldemort multiple times has surely left deep scars. Isolating himself might be his way of dealing with the post - trauma stress. He needs time alone to heal and come to terms with everything that has happened.
