Ok. In FF7 disc 2. When you are going after the large materias. You are on your way to get the sub(at junion) to go underwater. And while your on your way it will go to a short cut scene and Cloud will say "I feel like I am forgetting something.." It did this the last 3 times I beat the game.. What am I forgetting?

I can still just continue like always but is there something I could of gotten?
