Follow Him is the third quest of Chapter 2, "Fateful Encounters", in Final Fantasy VII Remake, taking place in Sector 8. While traveling to the Sector 8 Station to return home, an explosion in flaming buildings blocked Cloud Strife's path to the station. Following this, Cloud had a hallucination of a figure in his path, Sephiroth, and followed the figure forward.
As the quest begins, follow Sephiroth through the fire. Cloud's movement is drastically slowed, and the camera's vision is blurred. Cloud will eventually catch up to Sephiroth, at which point he will move forward. After following him into an alleyway, a cutscene commences when Sephiroth talks to Cloud.
Once the cutscene ends, this leads directly into the next quest, "Taking a Detour".
