Okay, semblance was his first guess. For the voice, at least. He knew that the eyes-closed trick was just that, a trick. Smokey just didn't know how the trick worked. And now that he knew, it was kind of irrelevant. There wasn't anything he could do about it, except maybe kick of cloud of smoke? No, he was still in fight mode, snap out of it!
His eyes narrow when she mentions looking at Good News. "Ya know, it's kinda rude to peek in other people's lockers. But if you really wanna know what's in there..." Smokey walks over to his locker and reaches out for the combination lock. He pauses for a minute, then looks back at Jima. "I hope this goes without saying, but no peeking on this one," he says before attempting to block all view from the lock with his body as he inputs the combination.
As he pulls away from the locker, Smokey's carrying a large, complicated-looking...hunk of metal? It's definitely more than that, but it looks more like some convoluted box rather than a weapon. He spends a bit of time looking it over, checking gears and knobs.
