[For a second, Sokka wonders why there's a sudden shift of focus from talking about fans and looking at gauntlets. However, once the phantom blade pops out, as close as it is to Sokka, he can't help but jump a little bit... even if the blade isn't pointed at Sokka.

[And the expression on his face is going to be comically concerned.

[But being visibly startled only lasts a moment, and Sokka begins to inspect the device a little more closely. He can't see the whole of the device, and he'd need to play with it in his hands to really make sense of it and reverse engineer it, but that doesn't mean that he's not already coming up with ideas.]

Iiiiinteresting. Hmmm, I mean, to make something like this, you're going to need a metal ribbing in the blades of the fan to begin with. Most of these will probably have to be deconstructed and reassembled, but...

[Half of this is spoken just to himself, but he's also verbalising it to Arno as if to say that he's figuring out his own plan for how to create it.]
