"No, it didn't even have a sun and there wasn't really a sky," Aqua answers. Light and darkness aren't really secrets. Most people know the concepts, even if they aren't familiar with the monsters born of them or the keyblade warriors who fight those monsters. "Time doesn't pass there, not like it does here." She always knew that getting back to the realm of light was her ultimate goal while she was stranded and that eventually she would have to adjust to life in the realm of light again. Even so, she's still having a hard time adjusting now. Maybe that's just having been thrown somewhere unfamiliar.

"I understand that feeling." That's kind of how her life has been in the last ten years, except backwards. Years have passed in the realm of light, only feeling like a couple of hours to Aqua. "What kind of changes do you want to see?"

That seems like a safer topic. Better to focus on what's going on here in this realm.
