This episode.. it defenetly had the heat and the motion. So many patients brought in so quickly. I can imagine that in that kind of action you can get lost. This episode really developed the character of Dr. Lawrence. Showed his point of view to all that and made clearer that his problems are much more serious than we first thought.
Also Lucy is lately acting more and more mature and quite a way she has learned around. That's great. And Carter - dr. Lawrence does have something to teach for others. And Carter learns that there is no reason to regret and matters the inside not outside.
And Carol and that pregnant woman - another great story arch.
