Theo is a man of contradictions - his mood shifts from extreme to extreme depending on the situation. Sometimes he's strict to the point of cruelty, and then he risks it all to save Michael's life. He's a strange and changeable person, and difficult to figure out.

He is the doctor in charge of the project that is Michael Wiseman, he's a mysterious, anal Frankenstein - one moment exulting over his creation like Don King, the next cold and condescending. Amidst the group of scientists who contributed to the project, he's apparently the one getting most of the credit and the responsibility.

For unexplained reasons, he seems almost reluctant to follow through on his threats of death if Michael contacts anyone - he's much more amenable to simply scaring the life out of Roger. Not to mention the fact that he gives Michael a choice at the end of "On the Town" instead of taking the more pragmatic route of simply "recasting" the part, and then letting him visit his wife and secure her insurance money.
