Hector is a cheeky boy who likes to talks about himself and his experiences. He often tries to command the conversation when he, Julio and Mando are around. But he is also scared when they go flying in a small plane. Hector feels scared when he realizes the robbers are probably after them. He tries to console Mando, but he knows they are in trouble. Hector has never been in trouble like this. He had caused mischief as a young boy, but nothing this extreme.
