It's only polite to pay attention to the person talking when they are bringing what they know to the larger table and so Sephiroth intently listened to star Jack had already put clearly in their correspondence before.. It hadn't been easy for him to put the idea to Terra, the one to him that opening the Rift could potentially hurt most of all if something happened to him directly as a result. For all his attempts at pushing the vision as a tool with which many had been manipulated, there would always be that seed of doubt sitting there, double-checking anything he might hear or even think for himself.

"Met her before?" Really, given all the various Avatars and other persons of note in Crystallis that Jack might mean Sephiroth had a hunch with regards to the girl it had to be. The one in that park they'd met before on another of their various journeys not-of Crystallis, surrounded by the four Heroes which had sacrificed themselves. Others might not know, though, and it was important that the hunch was verified too.

Jack seemed very sure of what it was that needed to be achieved, Sephiroth was almost jealous in that regard being as he'd been at a lost for a great while. It was an admirable trait, but it was a pity that the plan laid out then was far less kosher than he thought it needed to be. All of those options had massive if's and but's associated with them, by his reckoning at least.

"I don't suppose there is very much of a plan as how to go about any of that, should we get that far? Given that, as I'm to understand it, we are like ants to such a being.

And what of the potential for unleashing a horde of shattered souls onto this World?"
