In this episode, Counselor Troi becomes impregnated by an unknown being. The fetus develops rapidly, completing full gestation in two days. The rate of growth seems to increase since the child ages 4 years in the following day. The child later is revealed to be a problem because he emits a radiation that causes a plague virus to grow (the virus is needed to make a cure).
When the captain becomes aware of her pregnancy, he calls a meeting of the heads of staff, Warf, Data, Dr Polaski (Dr Crusher is not on board), Geordi etc to determine what is to be done. About her pregnancy, her pregnancy. A conversation begins about the danger the potential fetus may threaten, if terminating the pregnancy would harm Troi, when they should terminate, what loss to science an abortion would be. Troi, meanwhile, has been forgotten. No one asks her what she wants for her body, her child. Even in a world of acceptable abortion, she is not given a choice. But she takes the choice for herself and decides to carry the fetus to term and raise the child. That is the right to choose, not only to choose abortion but also to choose to carry a fetus to term.
