Spider-Island Spider-Mannotations Supplemental - Who the Hell is the Gwen Stacy Clone?

If you're reading this blog, you probably know who Gwen Stacy is.  Spider-Man's girlfriend, pulled off the tricky hairband/go-go boots combo, father killed during Spider-Man/Doc Ock battle, later chucked off a bridge, source of constant guilt.  Pretty straightforward.  (I could also talk about the kids she had with Norman Osborn, but that's a conversation for another day - or preferably, never.)

But what about her clone?  She recently appeared in current Spider-crossover Spider-Island, only to be promptly killed off.  If you aren't a longtime reader, you probably weren't quite sure who she was, why she was still around, or why she was called "Joyce Delaney".  But that's why I'm here.  I'm a living fount of Spider-Man minutia, and I'm going to share it with you whether you like it or not.  So sit back and relax as I tell the terrible tale of the Gwen Stacy clone!  Also, you better make yourself a sandwich or something.  This could take a while.

Yeah, you better get used to saying that, Spidey.
