I can't say I agree - the 'has she still got what it takes?' implies that, while she's back to her old self, she hasn't fought crime for a good fifty-odd years, and has some catching up to do. Of course, I could be wrong - but I can't see why Marvel, having already put a young, fit Blonde Phantom back in regular continuity, would go to the trouble of using a time travel plot to bring another one forward. It seems somewhat pointless - it's like saying 'I have here a lovely omelet that I made myself. Now, I could eat this omelet or I could toss it in the garbage and make *dramatic hand gestures* ANOTHER omelet! Yes, I think I will do that!'
