The Mark Green episode with the pregnant woman was the best episode ever. They’ve never been able to repeat the intensity of that episode and it was just a good old medical story. No falling helicopters, explosions, shoot ups, tanks, tornadoes, killer viruses or precocious children stealing body parts.
I once saw an outtake from that episode. Anthony Edwards managed to get hold of a little fake Alien baby (from the series V) and he snuck it into that scene and “pulled it out” of the pregnant woman. Everyone was screaming.
