Quite a bold move for a Trickster to impersonate an inquisitor. Though, if I read I'm Not A Trickster correctly, there is at least some precedent...
Honestly, I would be surprised if the percentage of inquisitors who are Tricksters is in the single digits, and even more surprised if the higher-ups (those who aren't themselves Tricksters) didn't know this. It's right there in the name. If not for the fact that they do fill a basket now and then, I might think the whole thing was a false flag.
