I just read this too. I wish it had been completed. It is a neat story. I also have to say I think the author was wise to ignore canon on what Jor-el looks like. In fact, I am hoping at some point someone casts Jor-el and Superman with the same actor. I mean, hey, if Clark is 27 and watching a recording his father made before sending him off, then his father could easily be the same age. Just use one actor.
