Donovan clearly went through some kind of a change, both physical given his head and inside too, that caused him to be a total different man to his family. That his own wife believe he was replaced by an alien.
He has become distant, unemotional, harsh yet calculative.
Demetrius followed along but he has vague memories of his youth.
I can only wonder if some kind of an experiment caused this or Donovan lost his emotions and traumatized his son to follow along.
