Hello again!
Today I come with a video showing the first time you talk to Cesar.
Those who do not speak Spanish will not understand anything. My apologies. When I have the English version, put videos, I promise.
But anyway, just in case you are interested.
Greetings!

This explains is if it is not well understood.
In this chapter you talk to Caesar, but not see. It's in the cell below, and you speak through the hole of the mouse.
A mouse Caesar trained to steal food to the prisoners in adjacent cells.
Sorry for my english. Is really limited.
