User blog comment:D.Dragon123/Luffys mother theory./@comment-3387274-20110729105910

Dragon was considering being a revolutionary but had not decided for certain back when Luffy was growing up (Sabo's opinion was what swayed him, if you recall). If Luffy's mother was killed by the WG Dragon would have decided sooner.

I'd laugh if it turned out to be Jewelry Bonnie, but I doubt it will. It would also be funny if it turned out he was Boa hancock's half sister (same mother), but I don't know what to think about that theory...;
