Two focuses here. The first is the whole Paula/Donna thing. We should know from watching the show how fragile a character Paula is. She is a psychiatrist, and yet she can't begin to diagnose her own fears and trepidation. We know Harvey can't stand weakness. It seems that she is incapable of seeing down the road and, I sometimes wonder, if she really wants and end to the whole thing. Louis goes off the deep end in his Sheila thing. They have role playing sex and he dives in totally. Gretchen has some of the greatest line in the entire series when she warns him about what could be the results of his actions.
