The aliens have made their choice.

Soon the aliens shall abduct Aiden. You rearrange the letters and it is "Adien." Adien is one letter off from being "alien," so that is a sign that he is here for a very special purpose. This human is unlike any other. What is there to do but perform experiments on him to see what exactly makes him different. Then when they get that information they will use it for their own purposes. They will take genetic material from him to advance their own species.
