The story of an unlikely mother discovering her feelings, the story of a a son acting against his destructive heritage, the story of someone bred to be part of a collective and acting mindlessly discovering their unique identity then sacrificing it to save others. The stories about the son have been told many times before, e.g. Terminator 2, but this episode is far shorter, more condensed and thus the punchline hits even harder. It's a love letter to self-determination and overcoming destructive instincts. In essence, of becoming human.
