Does my client’s son have alien hybrid DNA? Is he under alien control?

He is not a hybrid as you fear. This is a slight misinterpretation of things by this psychic medium. Because of his heavy involvement with the extraterrestrials and their manipulations of him, she is seeing this intuitively as his having at least a partial extraterrestrial origin, when it is simply that he has been altered slightly by the extraterrestrials and their maneuvering and manipulation of him. He is an example of a child done a bit later in life, as his mother noted, that he was perfectly normal as an infant and a young child, and then along the way suddenly darkened and things began to accumulate in terms of erratic behavior and poor performance in school. This is a symptom of their program, that they simply have been behind in catching up to the latest generation of human young so they all receive manipulation to dim them and dumb them down, in effect, because of their greater intuitive reach and other capabilities.
