Casey's delivery

Casey delivered her children quickly, finishing in three minutes thanks to being able to open her snatch and "shoot them out", as she said earlier at 30 seconds per child. Within a minute of birth, the hybrids started growing at an exponential rate. In the 5 hours that normal grow took, they were full grown in 1/60th time, finishing in 5 minutes. Upon a remote check of their systems, Casey found out their enhanced shapeshifting ability allowed for the quick growth, but however their minds were still developing, needing another hour or so for full autonomy, and until then they could act under command. Now all she had to do was figure if she was going to test them out under command, when they were capable of acting on their own, or just wait until sis and Sarah got back before doing anything
