Dr. Amanda Breyken is Terry's mother, though she has been absent for most of his life.

Amanda is incredibly manipulative and doesn't care much for others; she only cares about what she can get from people. She's very quick-tempered and can be difficult to work with. In public, she often puts on a kind appearance, but in private, she's very hostile.

She is a scientist who specializes in biochemistry. She is the director for her lab and officially the head of the biochemistry department, but tends to share her responsibilities with Callinway.
