Berat didn't like someone being afraid of him, did he? He didn't enjoy this feeling.
And I think the fact that in spite of being Oralian she still chose to serve in the Guard gave him a lot to think about... Maybe those people weren't really traitors, as the official status insisted? Maybe they could still be good Cardassians, who cared about their Union and wanted to serve to the best of their abilities?
When he jumped to water and laughed - I had to laugh too
And I like his last thoughts. He's in love all right!
