Actually, this makes me think of another story somewhere on the archives about Clark being a freelance reporter and having a "son" who happens to be his clone, but the kid's deaf... Don't recall the name or author, though.
That would be Sunrei's
Above Alt Else . Excellent story.
This is a fun idea. So how could Clark get custody? Would he need to confide in Dr. Klein? How long would it take for Lois to get over the "betrayal"?
