Believe it or not, I actually do agree that Peter being the illegitimate father of Gwen's children was a bad idea (though it would have been better than what we actually got). And yes, I will concede that JMS isn't completely blame-free as he still wrote the story, but I still fault editorial in this instance more that the writer himself. It's pretty similar to the moronic "robot parents" revelation in Life-Theft; a story that was forced on David Michelinie (a usually good writer) by editorial.
