I agree that the EG would be the main target. My idea, tough, was that, until then, elder kain would have other more urgent concerns, since EG is now hiding underneath the ground. As to the idea of moebius’ soul inside raziel, I don’t think there’s anything in the story that would be an obstacle to that. On the contrary, when raziel ate his brethren’s souls during SR1, he acquired their special skills. Concerning to the more covert approach, I agree that the meeting of both kains ‘could’ create a paradox. Not necessarily would. And I guess this kind of approach (covert) would be more interesting than if they indeed met. As to the rest you mentioned, it makes perfect sense. Thanks for the explanations.
