Hector Vargas: Miguel's mother's my sister. Miguel's father was killed 12 years ago in an accident. And now her son lies there murdered, thousands of miles from home. I feel it's my duty to scrutinize this investigation every step of the way. Please put yourself in my shoes. If you had a relative that was killed in a foreign country, wouldn't you do the same?
Mac: I would. But not by jeopardizing the crime scene.
