Counselor Troi becomes a non-consensual random vessel for an energy only life form to become human via super accelerated pregnancy. The baby is born a male despite no male being involved; perhaps the energy life form synthesized an Y chromosome? The baby grows like a weed but doesn't last long as the Enterprise is carrying dangerous cargo that might become lethal due to the presence of the boy. Rather than get a shuttle and depart the ship, the boy quickly decides to end its human existence and go back to being a pure energy life form. He didn't seem overly upset about it but Troi was very distraught. I felt bad for Troi but I'm sure she'll be okay by the next episode.
