Writing for Fun and Profit

I'm having an immense ball writing one of my character's introduction into the story.

He, like all the characters, falls into immediate stereotyping, but it is easily side-stepped, by proving these stereotypes are anything but. The stereotypes helps the reader fit the character into their mind, but then I am able to manipulate the perception of their character.

This particular fellow joins the story with a fair amount of baggage, but his needs to remain anonymous and helpful ensure that people do not get suspicious about his origins.
