who's coming to Smallville?
I could see Martian Manhumter in Smallville Season 11. With the close of Season 10, MM's place in the story ended, as did Jor-El's. But Season 11 has at least two story arcs that involve outer space (the Guardian disaster, the Earth-two crisis) and MM could come in quite handy for the off-world stuff. Plus, MM is such a cool guy. Kara could come in handy here, too. I'm still wondering how they will solve the <S> radioactive isotope tracking system.
