I echo those who have grown to love Nurse Crane. Never disliked her really but I kind of expected they would have her come along, stir things up and be sent packing with everyone being "yea, she's gone!" Instead, she has stayed, made an impact on everyone while becoming a deeper character. I like how she kept her personality--and still bumps up against what others prefer--while becoming integrated and a real part of the crew.
This show definitely made me appreciate living in the modern world with less judgment on pregnancies. I take things for granted--had 2 children while working and of course had no worries about getting fired, etc. But it really was not that long ago the opposite was true.
