"I'll remember that." Cloud speaks it as if from a memory or dream. This place had surprised him the first time too. He hadn't believed seeing Aerith knowing she had been somewhere else at the time. There's more to these memories that not even Cayde fully knows.

He closes the gap between them while looking right at the Exo with the glow of his eyes. "I'll always hold on to them more than you know. They helped me to remind myself who I am at one time. To relive them again is helpful in some ways."

It's the only words he could say to Cayde. "You live your life you wanna live." Cloud knows after saying that Cayde would be disappearing from the room. His time would be over here.
