Headscratchers: Starman

The DC comic

  • When Jack Knight and Mikaal are sent back in time, and they visit Krypton before it exploded, Jack immediately recognizes Jor-El as "Superman's dad" based on his name alone. Now, Jack is hardly pals with Supes, so is Superman's planet of birth and his ancestry supposed to be common knowledge?
    • At this point in the DC Universe it's pretty common knowledge that Superman is Kal-El and from the planet Krypton.
