I really screwed up this time.
The brig on this ship is quite the confinement. Tzekel-Kan is now imprisoned by Cortes for lying to him about where El Dorado was located. Actually, the former High Priest didn't lie. Tulio and Miguel sealed up the entrance before they showed up. Although he has last seen of them with Chel outside the city, his pleas were ignored.
As a result, he is now a slave by the very person whom he called a 'god'.
"Time to work, you heathen," Cortes opened the cell.
Tzekel-Kan is seen on the bridge of the ship mopping the floor as his work for the day. He will never forget the other work he did on the day he became their slave. This includes scrubbing off the dirt from their feet, washing the dishes from the plates they eat, and of course cleaning up every part of the ship.
He needed to get away from all this.
"Um, may I ask you something important?" he tries to get one of Cortes' men to face him.
"What is it?" that got his attention.
"When do I get the work done?" he asked.
"You don't. We will never let you finish all of it."
Hearing those words made it obvious to the former High Priest of El Dorado. He is trapped in this ship for the rest of his life as a slave.
Guess this is what being a slave is like.
