I know it's not in the rules anywhere, but I don't think that it's a spoken rule on the show. However, everyone who is asked on a date basically does have to go on that date. Now, as we saw earlier, sometimes those dates can end early. And that's perfectly allowed. But, I don't really want people to get confused. When a character is asked out on a date, the crew and producers all expect them to go on that date.<br/><br/>Once couples start to get established, new arrivals will likely not try to date a bird or a geezer who are in a committed thing with another islander.
