Answer:
Here is a rewritten summary of why Tzekel-Kan begins to doubt Miguel and Tulio’s story about being gods.
He notices that they do not know the traditions and ceremonies of the city, such as the game with a ball and the celebration with food. He also sees that they are scared of high places and do not know how to fly.
He sees that they bleed when they get hurt, which goes against his belief that gods are eternal and cannot be harmed.
He hears them fighting with each other and saying their real names and that they are tricksters. He also finds out that they have a map to El Dorado, which he thinks is a holy object that only the gods should have.
He sees them being kind and friendly with the people, especially Chel, who he thinks is a betrayer. He thinks that the gods should be cruel and demanding, and that they should only like him as their faithful follower.
These things make Tzekel-Kan doubtful and angry at Miguel and Tulio, and he tries to show that they are liars and take their place. He finally calls a big stone jaguar to attack them, hoping to show that they are not gods and that he is the real chosen one.
