Mister Gadget, in the final season, is of course the late John Spencer, The West Wing's Leo McGarry. That's why I was asking about Clark's citizenship a couple of weeks ago - I've been thinking of writing something in which he ends up meeting Leo and does a huge double-take, but I don't think that citizenship is the right route to that scene. Also I want to get more of my Highlander crossover written first.
