If they impregnate Sil while she is still in the lab, they could have studied how her species reproduces instead of wondering and speculating while hunting her down. Maybe they could see what the resulting offspring would be too and maybe even determine that her species is safe to allow to reproduce.

shareIt wasn't an option. Sil hadn't even hit puberty when she escaped. They couldn't have impregnated her even if they wanted to try.
