I get that the author needs it a conceit to make their story work, but all these organizations that put resources into people and then discard them on uncertainty is ridiculous. This is a world were skills are power and are determinative, this was a person you put time and resources into, and they were given an unknown skill... Study the damn skill before deciding if the person is worth keeping or not. Knowledge is power and finding an unknown skill should only ever be a boon, if only to determine its usefulness or uselessness for future cases. So short-sighted and, honestly, lazy writing.
