[The question of whether he's made the right decision or not is going to plague Nathan for a while. Whether he should have argued harder against Tony's plan . . . In the end, it had come down to the idea that if he argued too much, Tony might try to avoid him and cut off the only potential lifeline he has if things go bad.]

I've looked into it since Ryuzaki has made himself known. [Because don't go thinking he didn't get paranoid about that.] I have not found anything either way, so I suppose I cannot say anything one hundred percent definitive. He theoretically has the skills to stay under the radar, but from what I observed of him, he hardly has such an inclination.

[He'd never so much as spoken to his double, but he'd observed him on the network. All signs point to him being very social, and frankly rather dimwitted. Skilled in areas that Nathan is skilled in, but lacking his patience and caution. Even if he hasn't shown up on the network, Nathan likes to think his research would have turned up something on him.]

He does seem to take a great deal of pride in such a thing. [Hence Nathan's decision to only observe, not engage. If given the proper opportunity, he has little doubt that Ryuzaki would be absolutely horrible to him.]
