whether it's true or not is irrelevant, but it can't be the first time you've heard that?? It's why every time they bring in a clone or daughter or look alike or hint at a resurrection everyone loses their mind. There's always that hint of a ghost that the only reason he married MJ was because Gwen died... if she had survived, things would be very different.
Though either way... that list has both Flash Thompson and Felicia higher on the list than either of the girls so in my mind it's already void.
