That's actually an interesting point. Peter's on the outs with S.H.I.E.L.D. thanks to invading Symkaria to take out Norman Osborn and has probably alienated the general public as well with the collapse of Parker Industries. Ben's actions in The Clone Conspiracy would also likely render him Public Enemy Number One if anyone in S.H.I.E.L.D. or the superhero community knew he was still alive, and he's living on borrowed time, as is Kaine, who is determined to hunt him down and kill him for what he did. In that light, it's my great hope that Peter does eventually find out Ben is still alive and goes to confront him, while also having to clash with Kaine depending on whether or not Kaine still thinks Ben needs to die for what he did.
That aside, I definitely appreciate you trying to encourage us in the Spider-Fandom to check out Ben Reilly, even if this current iteration of the character isn't to everyone's taste, Pav. I love your argument about how the Scarlet Spiders' existence brings in these complex philosophical questions about identity, morality, memory, and even the human soul itself and like you, I'm looking forward to seeing those questions explored and maybe answered in greater depth as Ben's story continues and intertwines with Kaine's (and hopefully Peter's). We've all gotta get out there and chip in, and I've been buying each issue so far as it comes out. I'm not completely sold on what's been done to Ben's character, but I'm still willing to ride it out for as long as the series lasts. That remind you of anyone?
