Dude would have the perfect expertise for the project, but if he actually put it to use, he would be scorned. I guess that's the problem of hiding it from the beginning. If he hadn't hidden it, but obviously also wouldn't have advertised it, that is, he had just behaved as if it was nothing out of the ordinary, the other employees probably wouldn't have bothered to pay attention to it for too long. In the first place, it's not like it has anything to do with his work or workplace, so it wouldn't show in the first place.
