@dark_guyver: in the comic the Amazing Spider-Man he's grown up
ROFL, the man-child of the Mephistoverse is the farthest thing from a grown-up in the regular comics. Renew Your Vows Peter is the true adult out of the pair of them. Same with the late "MC2" version of Peter.
This would be perfect, if the events of One More Day never happened(Thanks to battleworld), and Spiderman is married(to MJ) with a kid on the way, so he lets Miles be Spider-man and mentors him. It'd be a very organic way for Miles to become the main spider-man
