I must admit, I did enjoy the dialog between them for a majority of the series thus far, it just seems that a lot of it is already starting to be recycled. For instance, Horo's teasing about how Lawrence wants her (and women in general) to be weak and needy. She said it at least 3 times, and Lawrence's responded every time like it was the first time he heard it (aka, no response at all). Or perhaps the theme where he's given the option to use/sacrifice Horo for his own ends (also 3 times). Or the jealousy theme (Pretty much every other female character introduced...).
Oh, and I don't necessarily mean sex when I mention resolution. If this were ecchi or hentai, then yeah, but really any MUTUAL agreement of commitment or even feelings would be more likely, and would basically fit the requirements to constitute as closure. Basically, the end of the flirting/courtship stage.
