Of course I know that compared to humans, Kryptonians are less volatile and publicly expressive, but I couldn't help making the Star Trek reference.

I was expecting Davis to wake up and freak out, but I really didn't expect him to kill Jimmy! And I still want to know where the freaking sword came from!

I'm ok with Clark making this particular mistake, because I'm sure it's connected to the Kandor plot--and really, even non-superhuman people blame themselves when people they love die, so I can see why someone who takes the weight of the world on his shoulders would do so too.
