@ TOC: Okay, you are forgiven! In fact, I can sympathize. But I won't judge Clark or Caitlyn for what Classicalla lets them do. After all, its not their fault!
And, another stupid question regarding the plot: Why on earth doesn't Jon consult Los about his health? He is a healer, even a good one.
And he has quite some experience with the kryptonian physiology and anatomy. Even better, let Los and Caitlyn do the checkup together.
