Midway through the season, when many of the islanders start to (metaphorically) sail off into the sunset in their happy couplings, the producers will move either the men or the women into the neighbouring Casa Amor villa, without warning. Then, an entire new set of islanders will enter the villas — the men will meet new women, and vice versa. At the end of the week, each of the original islanders will be forced to decide whether to remain with their original partner or couple up with a new person. There are always one or two long-term couples ripped apart by Casa Amor, but trust me when I say it'll be great TV.
