Disclaimer: All of these characters (except for Unnamed Girl) are owned by somebody other than me. I am not making any money off of these stories. I am of the opinion that nobody should be making any money off Smallville, not even the license holders, because frankly the stuff they're turning out is crap and they really should release their characters (at least Chloe Sullivan) into the public domain where they can run free and not be boxed in by the walls of Mythos and Iconocity and Other Such Nonsense.
