The Superman logo isn't intended for Smallville because Smallville is about the growth and development of Clark Kent and everything in between that get's him ready to embrace his destiny. So, when the show ends he'll basically just begin to be called "superman", which is why Louis doesn't fit into the plot of Smallville, I might add. I heard that they might do a movie to end the show completely, but I'm not sure when. Oh, that isn't the movie that's suppose to be a 2 hour episode conclusion. is It? If so, that's coming up quick.
