Why did Aason speak so well, even as a baby?

In the middle part of Rome's Revolution, Rome is reconnected to the Overmind of Deucado and this allows her to speak to Aason, even while he was still in the womb. This part of the book has always been a fan favorite. This is an actual quote from a reviewer on Amazon:

One of the real treasures of the book was "the baby". I fell in love with the baby and his relationship with his mother.

However, not every reader likes this. Here is one reader's comments:

I did have one thing that was difficult to suspend my believe (sic) with. The fact that Rome could talk to Aason and he could communicate back in an adult manor (sic). As a parent myself, communication with a child is difficult at any age. I just would have had a easier time accepting the conversations if the language the baby used was more simplistic and more inquisitive.

Well, the answer is, Aason does not speak at all. He communicates using thoughts. The fact that I translate his thoughts into English uses language controlled by the Overmind.

There is so much I could not put in the book as it was too long to begin with but all Vuduri children are connected to the Overmind from the moment of conception. You will see this again in Rome’s Evolution. Therefore, their mental communication is mediated by the Overmind which has fully developed language skills except it isn’t a language. It is pure thought which I render into English so the reader can experience the dialog. However, if you look closely at the content of the communication, you will see the baby’s thoughts are extremely primitive. This is a rare instance where you must separate the communication channel from the communication itself.

So that's the answer. Go back and look not at how Aason talks but what he actually says. You will see it is very primitive and baby-like. But he does grow up eventually and becomes the hero of The Milk Run which should be ready early in 2014.
