What do you think Estevan means when he says "don't be so sure until you have all the facts," and what theme does this relate to? What does Taylor mean when she says that "a certain kind of horror is beyond tears"?

Estevan has been through the Hell of being forced to abandon his child. He and his wife have endured a corrupt lying government where things are seldom what they seem. Taylor is referring to the horror of losing a child and not knowing the child's fate as beyond tears.
