Adam is extremely insecure about his job security. This has made him very competitive with his coworkers, as he is constantly worried that his job will be eliminated. He also gets very nervous when Mac Taylor is around as he worries Mac will fire him or get very angry at him. Adam is very skittish, and most of his speaking consists of him stammering through sentences, sometimes resulting in his going off on tangents and others gently coaxing him back. He does, however, gain some degree of confidence in himself when he does something impressive, such as accessing Mac's computer remotely or discovering what the odd combination of substances on a victim's clothing was.
