I could get used to this daily posting thing.
LOL at Jon's eyebrows, and I'm glad he had the talk with Clark even if it seemed to bounce off his invulnerable lunkheaded skin.
I can't say I'm happy that you're going with the Silver Age version of Jon and Martha's deaths (no easy time travel to explain it, is there?), and I had no idea this Mordru guy is that Clark referenced as possibly killing him; but hey, it's your story line, and it looks all good. Especially the dumping Lana bit.
I was a little taken aback at Clark's passionate comment that his biology has changed since he set foot on Earth. He knows this how? I also was a bit surprised to see Clark, as a teen, worrying about the possibility of having children. I understand his angst factor is more vamped up than most teens, but I would expect him to be more worried about relationships than progeny at this point.
Loved the line about "winding up his spine." You do know how to employ a good turn of phrase.
Bring on Metropolis! Tomorrow would be fine, or even today.
