With regards to Tasu, Delilah will fill in the blanks as to what's going on.  the scientists want to figure out how the unbirthing process differs from copulative birth.  (it's an actual word, I swear.)<br/><br/>As to the larger plot, for a while the scientists are in control.  it will sort of be a next chapter when the "escape or something else" happens...  Okay, so it's gonna be the something else option, but it's gonna be enough to get everyone out of their cells in the second chapter.
