  1. This season introduces Lois Lane. She appears as a special guest star in thirteen episodes before joining the main cast the following year. In addition, comics characters Bridgette Crosby, Bart Allen, Lucy Lane, Sam Lane, and Mikhail Mxyzptlk make an appearance.
  2. Clark recovered the first of the Stones of Power at the very beginning in Crusade. Then he recovered the last two in the very last episode, Commencement.
  3. Black kryptonite is introduced in Crusade, and is the second creation of Smallville (first being Lionel Luthor) to be incorporated in the comic books. It is also the third kryptonite introduced (first being green kryptonite and the second being red kryptonite).
  4. With Bart Allen's appearance, this is the first season of Smallville to feature an appearance from a DC Comics character who isn't part of the Superman mythology.
  5. Although Clark doesn't get any new powers, it is shown that Kal-El can fly. (Crusade). And by now, he's acquired and mastered all of his abilities, except super breath/arctic breath and flight.
  6. Originally Clark was supposed to gain his Arctic breath ability in an episode titled Cold. The story was ultimately told in Season Six in the episode Sneeze with the Arctic breath becoming Super breath.[1]
  7. Allison Mack did not appear in the opening credits of the first episode during its original airing. This was a tactic to maintain suspense of Chloe's fate, as she had been shown to be caught in an explosion in Covenant. She is not confirmed to be alive until the end of the season premiere, Crusade. She does appear in the opening credits of every other episode and reruns, after Jensen Ackles.
  8. Jensen Ackles appeared in 20 of 22 episodes this season (Onyx and Ageless being the exceptions.) This was the only season that he appeared on Smallville.
  9. This is the last season with this style of opening credits.
  10. This is the first season to have both first-and-last episodes starting with the same letter (Crusade, Commencement)
  11. This is also Jonathan Kent's last full season; he would appear only half of the fifth season, to die in the episode Reckoning.
  12. Chloe discovers Clark's secret this year. This makes her the second regular cast member to discover Clark's secret (the first being Pete Ross), and the first cast member to be aware of the secret before Clark confesses. (Pariah)
  13. Eric Johnson makes his final appearance as Whitney Fordman (Facade).
  14. Former Lois Lane actress, Margot Kidder, guest starred in two episodes this season.
  15. On the back of this season's DVD, it advertises 'Doomsday'. However, this is referring to the meteor shower in Commencement, not the season eight character.
