The word "uptake" does mean "understanding/comprehension," but I don't think it's used the way you're using it. I think you mean that this is your "take."
You could stand to run this by a grammar beta. Commas missing, mostly.
This is more of a frame than a story. You could build a story on it, but there isn't much there now. Why would the mystery man care about one girl and some kids? You should at least pose the question.
