Oh yeah.. I forgot.. 1993... Hmmm.. then I guess it had to have been the autopsy that did it. I can really see Emily saying to her mother she "knew" it was a boy. So, nothing ever happened to contradict Emily's intuition, it has (with her family) changed to "Emily knew she would have a boy so we named him Emilio". Maybe people in her family happen to be good at guessing if their babies will be boys are girls.. so, they just expected (in 1993) her guess was probably right.
