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.
I don't think so. There haven't been any official announcements or indications that the HxH manga will continue. But you never know, maybe there'll be a surprise in the future.
