103 "The Arrival of the Tiny Pretty Soldier"

Light flirting goes on between Haruka and Michiru in this episode. Despite they are unable to pursue deep relationships, they still have each other. Haruka again hints at jealousy when Michiru is "surprised" that Haruka finds the goldfish she caught to be pretty. In response Michiru giggles lightly and replies "Maybe..."

Admittedly, Uranus doesn't help Moon and Mars out when they are struggling under Daimon Soyer's control when Neptune almost teasingly notes she isn't helping them out. Uranus replies by doing it so often, she'd be showing too much support to them. Again, she is keeping up with appearances, but I think she doesn't worry so much because she knows they can handle it.
