In Rules of Engagement, Ben offered to help clean up the Hot Spot with her. Later Ester's friends called Ben her boyfriend, and Ben at first denied it, but then excitedly asked Rook if he had a chance with her. Later when she became the chief, she hugged Ben and told him she and her kind would be good neighbors. She turned the water floating around him into snowflakes and ran off laughing. He then brought her a towel, and she blushed as he gazed at her. Ben turned into Water Hazard and splashed everyone with water to cool them down, even when Ester told him not to. She brought him to her friends' town and they played an alien version of hockey. Later when she realized her kind was doing evil things, she joins Ben's team.
