Ricky said:4. Those people here who quote "Spiderman will always have MJ, like Superman will allways have Loise", please remember, that before Amazing Spiderman #200, it would have been: "Spiderman will always have Gwen, ..."!
If MJ could replace some other girl, whe not replace MJ for a while?
Because it gets to the point where she becomes more than a supporting character; she's just as much part of Spder-Man as his costume or his webs. Especially since the movies are out and that's what people are familiar with.
