Gus, born sometime in December 1978, has been
Shawn Spencer's best friend since childhood. Together they co-own the detective agency "Psych". Gus attended Pomona College. Gus tends to be strait-laced and more cautious. He is the "
Watson" sidekick and has a crucial role in the cases the two solve. Gus is often shown to be academically advanced and knowledgeable on various things, particularly math and science; his experience with pharmaceutical sales aids Shawn in his investigations frequently. Unlike the Watson-style sidekick, Gus is not often stupefied by Shawn's crime-solving capabilities, and he often doubts how Shawn comes to some of his conclusions. While Shawn is the "superman detective", he does not see himself as above Gus. Despite both Shawn and Gus coming to rational conclusions from observable evidence, both occasionally indulge in supernatural explanations for crimes. == Characterization ==
