I don't know, it was a random thought that came to my head, don't mind me.
on a serious note though, supposing if I did have a role in that fictional world, I guess I could learn how to be a Detective, different upbringing different genetics and all that, a lot of things become possible.
Pretty sure Alicorn Ponies in Equestria would have a use for a private eye or an independent agent that investigates potential incursions. Princess Celestia or any other Alicorn Princess could have used somepony like that to alert them to the danger of Queen Chrysalis sooner. Twilight Sparkle is smart, however she did not have a good reason to suspect an incursion at the time, she actually thought that the marriage between Shining Armor and Cadance would not be interrupted, it did not occur to her that a Changeling Queen was attempting to turn them against each other until later on when Queen Chrysalis was forced out of her morphed state.
If they had a seasoned investigation team the incursion could have been halted sooner. How would I avoid being hunted down by Chrysalis? disguise, of course. Keeping your whereabouts concealed is a must when performing a dangerous operation like that. Which means, no flying, Changelings could spot a Pegasi doing that easily. My fear of Chrysalis would force me to come up with creative ways to avoid capture, but if I did get captured, best not make it too obvious that I was a friend of Mane Six.
