At first, Will would be in shock. But as time passes, he would start to analyze Hannibal's motives. He is a profiler, after all. He might try to use his psychological knowledge to manipulate Hannibal in return. He could also go through periods of anger, resenting Hannibal for taking away his freedom. And there might be moments of confusion as he tries to figure out if there is any part of Hannibal's actions that could be considered 'caring' in his warped way.
Clarice could also become very defiant. She is a strong - willed character. So, instead of cowering, she might constantly challenge Hannibal, trying to get under his skin and make him make mistakes. This could lead to some intense mental battles between them within the fanfiction.
Well, his motive might be related to his twisted sense of love. In the context of fanfiction, Hannibal could think that by kidnapping Will, he is protecting him. He may view the world as a dangerous place for Will, and his actions are a way to keep Will safe in his own, very abnormal way. Also, it could be a power play. He wants to show that he has the power to take Will whenever he wants, asserting his dominance over Will.
Perhaps it's a power play. Hannibal is a character who enjoys being in control. By kidnapping Clarice, he asserts his dominance over her. He can manipulate the situation, make her dependent on him in a way, and show that he has the upper hand. It's like a game to him, and Clarice is the most interesting piece on the board.
Will might initially be in shock. He trusts Hannibal to a certain extent, so the betrayal of being kidnapped would be a huge blow. He could be angry and try to fight back against Hannibal.
One possible motive could be his obsession with Will. Hannibal sees Will as a unique individual, almost like a kindred spirit in some ways. He might kidnap Will to have him all to himself, away from the outside world that he believes corrupts or misunderstands Will.
Some characters like Jack Crawford might be dismissive. He is a no - nonsense FBI agent and might think fanfiction is just a waste of time and not in line with the real investigation and profiling work he does. So he would probably just roll his eyes and move on.
One aspect of this fanfiction could be the exploration of the complex relationship between Hannibal and Will. Their love might be depicted as a twisted, yet deep emotional bond. It could involve their mutual understanding of each other's darkness.
Typically, it is legal. Fanfiction exists in a bit of a grey area legally, but for the most part, as long as it's non - commercial and not causing harm to the original brand or creators. The creators of Hannibal might not actively promote fanfiction, but they also don't usually go out of their way to stop it. So, if you're just enjoying the fan - created stories, you should be in the clear.
