Not to mention that the novels don't count as canon and the future isn't fixed.

Both F-Rogue and F-Lucy came from futures that either no longer exist or have branched off into a parallel universe of their own (judging by F-Lucy going back to the afterlife in her own timeline, Hiro seems to go this route with FT).
