Alpha: If I can see her coming from afar, dodging her isn't going to be a problem. Where lies the problem is that my omnidirectional scanner's radius is only 100m and it can't detect magical energy. However... *thinks for a moment* Maybe... if I can't directly detect supernatural energy, I can still detect the natural energy it emits! Using my photoreceptors, I could calculate the speed of an approaching source of red light based on the amount of blueshift caused by the Doppler effect and compare it to the maximum speed of other beings capable of non motorized flight. If the former is greater than the latter, then I can conclude it's a Sky Comet Dragon coming my way and quickly sink through the ground with my intangibility.

Oooor N.I.G.E.L. can just detect her genetic signature with your scanner.

Alpha: But I only have a distance of 100m to work with and the range for DNA analysis is half as long. She'll be 50m away the moment I scan her DNA and already up in my face by the time the analysis is completed, so it's not a valid option. Bah. I could just send a sacrificial Perfect Duplicate with a connection to N.I.G.E.L. collect a sample in my place.

I see... So duplication solves the problem once again.

Alpha: Yep. And "duplication is always the answer" remains truthful.
