Twins (1988)

Chosen answer: Vincent was a point of shame and regret. Nobody involved wanted Julius to know Vincent even existed.

Chosen answer: She could have been unconscious by that point.

Chosen answer: Although I wouldn't call one a bad guy, Professor Werner is the the one who raised Julius, and would remain a friend because of this bond. Mary Ann (the twins' mother) however, was told that Julius died at birth and was never told about Vincent. She blames Professor Traven for this (probably since he's the only one around to yell at). Vincent on the other hand was never told his mother died during childbirth and he grew up thinking his mother abandoned him. Until Julius showed up, he never knew he was part of an experiment and he had no knowledge of either doctors and probably no feelings regarding either of them.

Chosen answer: Because the offspring of this experiment was meant to be studied, researched. Mary-Ann showed signs of maternal attachment toward the end of her pregnancy, which the scientists involved felt would hinder the experiment due to her not wanting her baby poked and prodded at all day, every day. So she was told her baby died at birth and she was sent on her way. There was no point even mentioning the second baby since she never knew she was carrying twins in the first place.
