OK, if it's admiration, even flirtation, that's not horrible. But if it's a romance and goes bad which causes Susan to reject all things Narnia, that would be horrible. But if that is just speculation on our part, then I will not be too worried. And I am happy with Ben Barnes now, as far as his age, because they have done a good job in the teaser/trailer of making him look to be about Peter's age -- Will's age, either way.
