95 "Leave it to the Moon for Love Aid"

In this episode, during the Lover's Park: Affection Contest Haruka comments that Umino and Naru try too hard when the contest is a game. Michiru agrees, but thinks that to be "able to become that serious is a wonderful thing." Now most would say Haruka's reaction was of guilt for her harsh words, and while it is guilt, I think there is also a different sort of regret in her expression. That regret, I believe, is the fact that she and Michiru are unable to pursue such things (between them) due to their mission. They both long for a normal life.
