I'm not sure exactly. You might have to read or watch the story closely to find out.
A wizard who has dabbled in the Muggle world might give Harry a gun. This wizard could have seen the potential use of a Muggle weapon in the wizarding world's dangerous situations.
Often, it could be Dumbledore. He is a very authoritative figure in Harry's life and in the wizarding world in general. His orders usually carry great significance and often involve tasks related to the fight against Voldemort or the discovery of important magical secrets.
I'm not sure specifically as I haven't watched it directly. But generally, it might be about ghost guns which are often privately made firearms that lack serial numbers and are difficult to trace. It could cover aspects like how they are made, who is making them, and the potential implications for law enforcement and public safety.
Yes, it could be. The title 'the old man and the gun a ghost story' gives an impression of a spooky tale. If it is a movie, the 'ghost story' part might imply elements of the supernatural, and an old man with a gun in such a context can add to the mystery and potentially horror - like if he's a haunted figure or involved in some otherworldly events.
It could be a rogue wizard who has also acquired Muggle weapons and is using them to cause chaos. This wizard might be jealous of Harry's fame and wants to use the gun to prove that he's more powerful.
It could be some other wizard who Harry had an unexpected encounter with. Maybe it was a wizard who was secretly in love with Harry and used some sort of love - related magic that had an unforeseen consequence.
His friends like Hermione and Ron could also be important characters. Hermione might use her intelligence to help Harry during the pregnancy and after the birth, while Ron could provide some comical relief with his typical reactions.
The audience could be young students at Hogwarts who are eager to learn from Harry's real - life experiences in fighting dark wizards.
In this fanfic, Harry Potter is the protagonist. He is the one with the idea of giving the troll a job. The troll is the main character as well, as the story focuses on its new life with a job. Additionally, Dumbledore might be involved. He could be either supporting Harry's decision or warning him about the potential risks of having a troll in a certain role at Hogwarts.
It could be that the father is an unknown wizard who Harry had a brief encounter with. Maybe it was a one - time magical connection that led to the pregnancy.
