Well, perhaps the dragon that Jon Snow hatches is not like the normal dragons. It might be a sickly dragon at first, and Jon has to go on a dangerous quest to find a cure. This could lead him to encounter old enemies and make new allies. Also, the dragon could have the ability to change its form, which would be a huge shock to everyone in the story and create all kinds of chaos and confusion.
A plot twist could be that the dragon hatching is actually a trap set by the White Walkers. They knew that Jon Snow was the key to hatching this dragon, and they plan to use the dragon to their advantage. However, Jon discovers their plan and has to find a way to break the bond between the dragon and the White Walkers. This would involve a lot of internal struggle for Jon as he doesn't want to harm the dragon but also has to stop the White Walkers' evil plan.
One possible plot twist could be that the dragon has a special bond with Jon Snow that allows them to communicate telepathically. This would give Jon an edge in battles and political intrigue. Another could be that the dragon's hatching is part of a prophecy that no one expected Jon to fulfill, leading to a power struggle among the characters who thought they were the rightful ones in the prophecy.
Well, in the fanfic, it could be that Jon Snow stumbles upon the dragon egg while on a mission beyond the Wall. He might not even realize what it is at first. But as he holds it, some latent magic within him starts to interact with the egg. As it hatches, the dragon imprints on Jon like in some old legends. The dragon's presence then forces Jon to reevaluate his role in the world. He could use the dragon to fight the White Walkers more effectively, or he might face opposition from the current rulers who fear his new - found power. It could also open up a whole new arc where Jon has to learn how to train and communicate with his dragon.
Well, perhaps Jon finds a dragon egg in a hidden cave. He takes it home and starts to take care of it. As he does, he begins to notice strange markings on the egg that seem to glow at night. Eventually, the egg hatches and out comes a small, cute dragon that he names something like 'Spark'.
Well, one possibility could be that Jon Snow discovers some ancient magic in the North. Maybe while exploring a long - forgotten cave, he stumbles upon dragon eggs. His Targaryen blood somehow reacts to the eggs and he manages to hatch them. Then, he has to deal with the power and responsibility that comes with having dragons. He might use them to fight against the White Walkers, as they are a great weapon.
Maybe it's about Jon finding a dragon egg and through some magical or difficult process, he manages to hatch it. He could face challenges like protecting the egg from those who want to use it for evil, and once the dragon is hatched, they form a strong bond and go on adventures together.
In this fanfiction scenario, Jon Snow hatching a dragon would completely transform his relationship with Daenerys. At first, she might be in awe of the fact that Jon, a man she is already attracted to, has this new and powerful connection with a dragon. But as time goes on, power dynamics could shift. The dragon could act as a sort of mediator between them, or it could drive a wedge. If the dragon has a will of its own and favors Jon over Daenerys, it could cause a rift. However, if they can learn to work together with their dragons, they could become an unstoppable force in the fight against their common enemies.
One possible plot twist could be that Jon Snow, as a dragon, has to hide his true form from his former friends in the Night's Watch. They might see him as a threat now and he has to struggle to prove that he's still on their side, even in his new form.
One possible plot could be that Jon Snow discovers the dragon egg in a hidden place. He manages to hatch it through some unforeseen circumstances. Then, he has to keep it a secret while training it and learning to communicate with it.
One possible plot twist could be that Jon Snow goes back in time and accidentally changes something that leads to a completely different future for the Stark family. For example, he might prevent Ned Stark from going to King's Landing, which would change the power dynamics in Westeros entirely.
There could be a wise old wizard who gives Jon advice on how to hatch and take care of the dragon. Maybe there's also a rival of Jon's who is jealous of his discovery and tries to steal the dragon egg.
It could be a power - hungry wizard who wants the dragon for himself. He might try to steal the egg from Jon before it hatches or take the newly - hatched dragon by force.
