Hate to admit I didn't think of it until you all pointed it out, but it never entered my head, and I think you may be right---who is getting shot? Ben's competitors for his daughter's affections...her boyfriend and mom. And that "your mom will protect you" line? Perfect set up for when her mom can't protect her and she has to depend on being Ben's daughter to survive.
Of course the problem with that logic is that if any of Ben's friends come out of the bushes to capture her she will know that they aren't from the ship--after all, she knows everyone on the island. So the only way it works is if she now runs back to daddy Ben without further mishap...perhaps thinking they are following her to find him? How else would she explain being neither captured or shot to herself, except, of course, by thinking it might be a set up by dad?
Re the gay guy...yes, we knew about him before. On the one hand, he's the token gay guy...as in, the odds are there must be at least one gay person on the island! But maybe only one, since he has to "take advantage" of being off the island to have any fun. On the other hand, cool that it is just a minor mention, not a big deal, when it comes up, and that he's so counterstereotypical. Like the way they are treating race/national origin, kind of ho hum, compared to the BIG divisions on the island!
