We've not mentioned the Delusional Egomaniac before. He wants certian things done, but wont do anything about it apart from sending pissy emails every few months. Then, when the things don't get done, he uses that as evidence for his delusions that people are out to get him... And these delusions help feed his ego, by making it clear that he's important enough that people would be out to get him. And the bigger his ego gets, the bigger the delusions get.
It's like a schizophrenic ouroburous.
