Well Ironmike, if he has Autism (so many claim to have it) it precludes him from having standard social skills and he may come across as arrogant. I always would try to consider that too. The bad news is, that those afflicted with such may also find that their thinking is highly compartmentalised and rather rigid when it comes to things in general. This may turn out to affect his ability to translate what he knows into performance. Let's see does he come back with some thoughts on his tracks, if he has any.
