Knowing what he did -which was as little as the next Hero with a theory- about life energy mechanics on Crystallis, Sephiroth was not too taken with the idea that they weren't so much different from the indigenous monsters of his world, nor the idea that it meant that even in death it didn't mean the end. That was exactly what had happened to their doppelgangers, for sure, and they'd just been re-purposed into new life. Just like what happened back home.

Still, he listened to Ales intently, leaning forwards on his chair and resting on his elbows, near to his knees. Engaging his brain was a pastime that Sephiroth did an awful lot of and running new thoughts and theories through it was exciting, yet at the same time a long-tired exercise. It didn't do much for the festive revelry he had thought to at least try to be a part of, but that hadn't ever been much of his thing, either.

"Hm." With a furrowed brow he looked over Ales' crystal as he produced it. Spencer was custodian of his own crystal a lot of the time, especially as currently it wasn't like Sephiroth had much in the way of pockets to keep it in.

"I shall have to recontact with Cid, perhaps, about the preliminary notes I had made about the engine that used to power the Enterprise, see if he can release them in your direction." A sharp nod turned into something a shrug at the end though.

"It might help a little."
