I just dislike the idea of Peter having a mentor inserted into his mythos as it takes away what makes him a solo hero in the making. Something like this is okay in the Ultimate verse is okay given that Peter is young and that the world showed that S.H.I.E.L.D has more connections to every hero in that world unlike the 616 world.
However as Fans of the Superhero: What do you think about Spider-man having a mentor ?
