Franklin is how old again? 30? 40? How is it that he is the same age (seemingly) as he was when Val was born (and she's supposed to be 2 or 3)? Just let Frankie become a teen. The only person affected would really be Sue since they couldn't pretend she was 29-30 any more.
Also if Luke dies (I doubt it) how long before Jessica becomes just another member of the Spidey Romance & Hijinks comics titles (as I know call them)?
