Interesting story, or perhaps I should say anecdote. The Black Eyed children reside at the fringes of the whole alien phenomenon but I've yet to see anything other than stories to support their reality.
In this case we're not given nowhere near enough information in order to get close to an informed conclusion or opinion. What factors influenced this sighting and what happened prior to it? - we just don't know.
Are the Black Eyed children really the product of alien/human hybridisation, if they are what's their purpose?. More questions than answers but nothing concrete.
