Belated, but…
Oh, and I understand that the "not after 20 weeks" was to ensure you weren't putting any controversial images of late-term abortions into people's heads…
Squick as it may be to say, if memory serves I think when gishface and I were hashing out details the thought was, "it would likely be really harmful for both mother and child if a fetus over 20 weeks old was transferred into the womb of a woman who was not yet pregnant to begin with". The one thing the SCP object here will not do is harm the mother or the child.
Also, it would be a rather obvious spontaneous effect, and part of what I liked about the approach was that the Foundation would have to run a lot of damage control because the anomalous births were pretty hard to track.
The biologist in me had a field day reading this. +1.
I'm glad to hear that! :D gishface and I spent a lot of time on the internal consistency of the piece.
But, as the first line alludes to, there was some wordiness here and there.
Could you make some suggestions for trimming? I definitely prefer thrifty language, so I'd love to hear your thoughts on how to make this more succinct.
