chapter 4- Shasta falls in with the Narnians

So after Shasta is picked up by the Narnians, he is asked many questions about where he was and how he escaped.  Shasta has no idea on how he supposed to escape and go to the tombs.  Anyways the kings and queens stop asking him questions they start talking about this prince rabadash and how he wants to marry queen susan.  It's all kind of confusing.
