In fanfiction, when Sabo and Luffy meet again, they might have an emotional reunion. They could share stories of their adventures since they last saw each other. Sabo might show off his new skills or powers, and Luffy would be excited to see his brother again. They could also plan new adventures together, vowing to face any challenges as a team.
Well, it could be really exciting. Maybe Sabo brings some important information about the world government or a powerful treasure. They would hug tightly first, of course.

They might even have a friendly sparring match to test each other's strength.
They might have an epic battle to test Luffy's growth. Shanks could see how much stronger Luffy has become and be proud. Maybe Luffy will show off his new Haki abilities.

In a 'Sabo meets Luffy crew' fanfiction, there could be a lot of emotional reunions. Sabo might share his adventures since they last parted.

One possibility is that they would first be confused by each other's strange abilities. Naruto with his jutsus, and Luffy and Sabo with their Devil Fruit powers.
