i think we are on the same page, but just wording things badly... It is a key part to the plot, hence why it wasnt said. Its just foreshadowing that her name is very important and should be kept secret.
Like i said, it cant be a spoiler if nothing was said, and nothing is to be spoiled. Its like if she is hiding she is Lelouch's mother or anything.... Or could she... hmmm Now i get what you mean, but still there isnt enough said to imply that her name could be a spoiler
Things cant spoil if they arent there... Idk, BUT YOU GET MY POINT!! Lol
