someone already did in the tumblr link, anyway.. it wasn't me, sooo.. ._.
I like the psychological aspect of the theory. A "Death Note" type scenario would be nice in my opinion.
What's so ridiculous about pondering the idea of Kaneki maintaining some relationship with the "CCG," anyway? He just seemingly accomplished something that they've struggled to do for so long.
And remember, CCG is presumably a puppet organization for V for maintaining an equilibrium. V wanted Eto dead, they'll think Kaneki accomplished it. Since kaneki is such an unknown, and potentially powerful variable that could even work in their favor from their perspective...why would they waste that potential without asking the question?
They tried to bring Yoshimura back into the fold. What's ridiculous about them trying to recruit Kaneki at this point? Yes, it's far fetched but the idea isn't exactly illogical from what we know. They know enough about his psychological profile to where they think they might be able to control him, so who knows? It would all depend on the field agents' reactions to Kaneki and whether or not V is directly monitoring the mission IMO.
