[He could well have used a stronger word, than 'troublesome' but not only does Sephiroth not want to insult inadvertently, he also doesn't want to pique curiosity in the other man. Ace is not a fool, which is why Sephiroth is even talking to him at all, having earned a certain respect for those mannerisms that do seem to be a little similar between the two of them

As such, he silently listens, dedicating as much of his attention in Ace's direction as he explains, yet still remaining aware of their surroundings. Sephiroth is quick to see where Ace might have applied a little too much personal weight to this expedition. He nods, at least hoping that Ace will take his comment for what its worth.]

I see. Well it is rather parallel, one could argue.

[Being as who knew what they might find at the top of the Tower? Clearly being Ancient in origin and just from a journal he's managed to lynch from one of the floors, it did seem to have something to do with stopping Narayana -- that is, the Calamity. Not so far off preventing the destruction of the world, and by extension all of theirs.]

Hmm. [A kinder smile, not often seen on the other man stretches its way across the bottom of his face at Ace's last comment. He appreciates that, and also has a keen awareness personally of how certain things from others' worlds do have a tendency to correlate inexplicably.]

I doubt it will be the first unnerving correlation you might come across, if you'll allow me to speak from experience.
