PROMPT - The Great Pharmaceutical Mystery
In "If You're So Smart, Then Why Are You Dead?", the director of the gifted school expresses surprise that Gus became a pharmaceutical salesman, rather than a doctor or something. One of the Psych webisodes attempts to explain Gus's career choice (as teens, Shawn signs Gus up for information on pharmaceutical sales at a career fair), but I feel like this can't be the whole story. So what happened? How did a nice boy like Gus end up selling drugs? :-P
I'm planning to do this one myself eventually, but I probably won't get around to it for a while, and I'm curious how many different scenarios we can come up with.
