Smokey continues stroking his chin as Lunae offers her thoughts. ”Depends on how it’s loaded, I guess. It looks like it loads directly into the barrels from what I can tell, though,” he responds. He doesn’t see anywhere else to load ammunition, unless Ferus loads it through the barrel like an old-school musket, but Smokey doubts that’s the case.
Still, Lunae’s explanation of two of the exit points causes a bit of confusion on Smokey’s end. ”But wait, if you tried to fire anything that large, the recoil would ensure you’d miss at anything beyond point blank! You’d have to have some way to compensate for that—wait, can you ignore recoil, too?!” he asks, incredulous. He quickly regains his thoughts and mutters, ”No, that’s probably not right. If you could ignore recoil, you’d probably use a bigger gun than that. But still…” Smokey’s pauses and stares at Grim Repertoire, trying to piece together how the professor would use it.
It looks like he was partially right about a flamethrower add-on, though it only seems to be one of the exit points and not all three, and it looks like it can use any type of dust. That’s two of the three exit points, though he still has questions about the first one. The third one remains a mystery, though. If Lunae hasn’t seen it in action, then that means she hasn’t seen a situation where its use was warranted. More specifically, it means she hasn’t seen the professor in a situation that he couldn’t resolve with his lance, the point-blank “shotgun” (for want of a better term), or the dust thrower.
”The last exit point’s probably a ranged option,” Smokey guesses. ”If it’s for something like a Giant Nevermore, then it’s probably something hefty, too, though the recoil would almost definitely still be an issue. Since I don’t see any scopes on it, I’d wager it’s for a medium-range slug of some sort,” he explains to no one in particular. He’s probably way off, though. A Nevermore could stay high in the sky and just rain feathers down on ill-equipped fighters, so the only real way to fight it is with long-range weaponry unless it decided to dive bomb. Granted, it’s a Grimm, and thus not very smart, but the point remains. And then there's the recoil issue, which hasn't gone away. If the professor could handle recoil like Smokey could, then he wouldn't need a slug in the first place: the first firing chamber would be plenty. If that were the case, then it's almost definitely something else.
