It'd take a lot more than sleep to get the drop on me. But no, I still don't care much anymore.
Actually that's not unheard of. I'm not the only clone of Clark out there either, there was another. He was also unhinged. Caused my death before I showed up here. Though beyond him I'm not sure there are others, but I guess it isn't out of the question.
The guy that created me was pretty pissed I developed a personality of my own, I'm sure he wanted to make more.
