Wariness and paranoia are very different, even if they feel the same to whomever they afflict. The latter implies an element of irrationality, even madness, and a more perceived than observed danger.

I think labeling this piece as paranoia suggests that Ignus has no reason to believe that Vaati is in danger, but can't help himself from worrying needlessly. Or rather, that his reason is irrational. I suppose one could interpret it as Ignus fearing that fate will somehow twist itself back around and force Vaati down a dark path, despite his efforts.

It was more the idea of having to draw a general unease twice in a row that gave me pause, even if they're ultimately two different kinds. Glad I stuck with it though, because that's precisely Ignus' biggest fear. He is a chronic worrier, heh.
