potential trouble source: a person who is in some way connected to and being adversely affected by a suppressive person. Such a person is called a potential trouble source because he can be a lot of trouble to himself and to others.
Trouble like not getting enough sleep to be sharp and present for big projects, trouble like thinking one thing was said when another was said, trouble like ordering the supplies for the wrong store, trouble like never quite getting around to completing the projects, trouble like not quite stating the whole picture so that people know what you need. Yes, a person in that situation is aptly named. I'm glad to have a label for it -otherwise it could drive someone nuts.
