While he's vaguely aware of Kaito and being watched, it's more out of the habit of being aware of his environment and always out in plain view. The actual concern here, though, Sora's actual enemy, is this MOTHER-FUCKING CABIN. And this fucker is going down (or such is the plan, if the dark grin on his face can be trusted). In a rather literal sense, too, as the walls take a hard hit, the winds ripping at them relentlessly, not letting up in the least as the cheap wood begins to groan and crack and the pieces give way, debris flying through the air at fatal speed.

...and yet, for some reason, something about the destruction-in-progress doesn't seem to be going quite right.
