Oh yes, you have to let Bill keep the powers -- I like the idea of a Metropolis with three super-heros <g> And Sue went to all that trouble about dreaming up a costume, too.
I confess, I'm curious about Sue meeting L&C, especially Lois... maybe they can have them over for dinner and Lois can give tips on the finer points of being married to a superman
Or if that doesn't fit in your story (since there's only one more part), I'll just imagine it <g>
Or, of course, I could just wait for the inevitable sequel
