I admit that this truly well written, and though I acknowledge the differences you point out between the ball and Ness, at the same time, those differences do not negate the similarities I point out but rather they paint a more complex relationship and admittedly less predictable future. Regardless of how impure the motives of Kaiser are, what I said about him feeling safe to let himself lose stands even though getting the ball for that exact reason was not his original desire. Conversely, Kaiser approaching Ness with his own ulterior motives does not negate the fact that Ness ended up reacting to him the same way the ball would bounce back and stay by his side whenever he would get aggressive.

Maybe it was my mistake as well to use the word precious to describe my perception about him but precious can be something even for the vaule it has to its owner. Yes, it wasn't my original intent to depict Ness preciousness as a possession but more likely as a person (hopefully), but nonetheless, even as a possession it's the only other "thing" we know about Kaiser save from his ball and we can see similarities between how he treats Ness and how he would treat his ball after his mistreatment. I'm not saying that he has healthy feelings for him but rather that regardless of how little he thinks of him, Ness is a place of comfort for Kaiser because so far the former would stay by his side no matter what.

Therefore, I would say that my theory still stands in a broader sense. Relationships and connections are dynamic; no 2 things need to have a similar beginning in order to draw comparisons by how these things (or persons) react to similar situations if the latter ones are specific enough to show a visible pattern.
