The Spanish say that they cannot be fooled; the Tlaxcallans have informed them of who is who

Chapter 13
Moctezuma sends more sorcerers to cast spells on the Spanish; this is yet another reversal of his position.
The sorcerers meet up with a "drunken youth," a Chalcan.  This "drunken youth" asks the sorcerers all sorts of questions. The "drunken youth" warns that Moctezuma has abandoned his people and thus destroyed his people.

This "drunken youth" then launches into a prophecy' "Nevermore will there be a Mexico; it is already [gone] forever" (34).
Moctezuma's sorcerers then realize that this "drunken youth"  is Tezcatlipoca

The Encyclopedia Britannica on Huitzilopochotli:
