Interesting points earlier about it being just a show and the women all still in competition, so anything goes. I actually agree with them. However, I also agree with the others who said it was about personality.
No, the other women aren't engaged to him. But they think that the most that's going with each other is passionate kissing. The fact that Ben concealed it is what clinches it for me. Jennifer said in her post-show exit interview that she had no idea it had happened, which pretty much means that none of them did. So he sneaks out behind their backs to go skinny dipping, and then just a few hours later stands up in front of them with a perfectly straight face and gives them roses. And the whole time, the woman that he had just been cavorting with was standing right there. My Southern grandmother would sum up Ben in one word, "Tacky." She'd have stronger language for Coutenay, but wouldn't repeat it in polite society.
When somebody says, "the most glamorous city in South America" what do you think? Buenos Aires? Rio? Panama City? Just imagining the women's reactions makes me want to LOL.
And finally, I've heard people mention a scene where Ben just stands by and lets a woman chuck her own suitcase into the trunk. People are saying that Ben was ungallant for doing that. Where does the scene occur?
