Well, for me, it could be the first encounter. When the two characters meet in a really unexpected or funny way, like bumping into each other and then starting to argue but there's a spark. Another memorable moment might be when one of them makes a grand, stupid gesture to win the other's heart, like showing up at their work with a big sign saying 'I love you'. And of course, the moment when they finally realize they are meant to be together despite all the crazy things that happened before.
Gon in fanfiction can be very single - minded in his pursuit of goals, just like in the original. He might be a bit more naive at times, which can lead to interesting plot twists. Killua is often portrayed as having a complex emotional side. He struggles with his past as an assassin and his loyalty to Gon. His cool exterior may crack in some fanfictions, showing his true feelings.
Gon would probably be angry at first. He has a strong sense of justice and being kidnapped against his will would surely make him mad. He'd try to fight back immediately if he had the chance.
In gon and pitou lemon fanfic, Gon could be depicted as being in a complex emotional state when it comes to Pitou. Maybe he's conflicted between his hatred for what Pitou has done and an unexpected attraction. Pitou, on the other hand, might be presented as having a deeper understanding of Gon than in the original story, which leads to some rather unorthodox interactions between them. However, it's important to note that these are often extreme interpretations in lemon fanfics and not necessarily in line with the overall tone of the original series.
One memorable moment is when Crazy Eyes reads her writing to the other inmates. It shows her vulnerability and her creative side. Another is when she tries to form a special bond with Piper, which is both sweet and a bit awkward. And also, her moments of outburst are quite striking as they really show the depth of her character and the challenges she faces with her mental state.
It's hard to pinpoint exactly where Gon is in the manga at any given moment. It all depends on the current events and his adventures. He could be in a forest, a town, or some other setting relevant to the story's progression.
Gon undergoes a series of intense challenges and character developments. He faces powerful enemies and has to make tough choices that shape his journey.
