Kryptonite: It causes Clark pain, could possibly kill him, and temporarily strips him of those differences which separate him from Steve in Accounting.
What if it also did something else, besides? For example, how would Green Glow of Home have been different if, in addition to being rendered powerless, Clark had also become temporarily blind? or deaf? Suppose, after escaping Luthor's Kryptonite cage, he found himself not only powerless, but completely invisible? Or conversely, what if his hair and/or skin turned such a loud color that anyone who saw him would suspect something wasn't normal?
What are the possibilities, do you think?
