He could meet an AU version of Hinata who is more assertive and outgoing. Maybe she's a powerful ninja in her own right and not as shy as in the original story.
In this fanfiction, the meeting with the grandfather could also be a source of conflict. Perhaps the grandfather has certain expectations or traditions that seem to be at odds with Shikaneji's relationship. This would create drama as they try to navigate their feelings while also dealing with the grandfather's views.
In a Shika Neji AU fanfiction where they meet their grandfather, it might be a very emotional encounter. The grandfather could be a symbol of their roots and heritage. He might have a unique power or ability that he passes on to them, either literally or through some wise advice. For instance, he could teach them how to face their inner demons or how to make the right decisions in difficult situations, which would then shape their characters and their roles in the fanfiction's plot.
If the grandfather is very warm and accepting, Shikaneji would feel relieved and happy. They might open up more about their relationship and their dreams. Nejire could start chatting excitedly about their future together, and Shinsou would relax and join in the conversation more. However, if the grandfather is not so friendly, they would be disappointed and perhaps a bit defensive.
