What's I found quite intriguing about the show since rewatching it is the amount of Pre-Crisis elements other than Clark and Lex knowing each other in Smallville, Clark meeting up with younger versions of certain heroes, that one time/episode where Lana was put in charge as editor of the school paper, even the idea that Smallville was picked as a destination for the rocket ship with baby Kal El to land via young Jor El's experience on Earth and the coordinates' signal being traced by Dr. Swan (Christopher Reeve) in the 70's sounds somewhat similar to the idea that Jor El sent a tracker to Earth with a recorded message when it landed near Albert Einstein's home, requesting the best environment for Kal El to land and be raised in from Elliot S! Maggin's Last Son Of Krypton novel.
