Not just comic time, but most entertainment timelines slide. A sitcom will have a baby born to add to the cast, next season the kid is 5. Or worse in soap operas. A kid is a young teen while a baby is born. They both disapear for awhile, then they suddenly come back the same age.
I collect Spider-Man and he's been around 10 or so years Marvel time. I remember his first fight with the Lizard. Conners son was just a kid, then each appearance after he'd get a bit older. In the 90s he was a teen. Didn't hear from him since then, comes back last year as a kid again.
I wouldn't mind if it was a kid they rescued or appeared earlier... just as long as it's not the Hudson baby, all grown up and recently returned from a sex-change operation.
