When Lana (possessed by Isobel) kills Genevieve Teague by stabbing her with one of the Kryptonian Knowledge Crystals after she attempts to steal it, it triggers a cosmic event that not only severs Lana's link to the spirit Isobel but also sends meteorites from deep space toward Earth and Smallville. At the graduation ceremony for Smallville High, the military arrives to evacuate the town after news that another meteor shower is imminent. Fearing he has a link to the meteorites, Clark goes to talk to the spirit of Jor-El, who informs him that his only hope is to unite the knowledge crystals in the cave. With time running out, Clark sets about locating the final two crystals as meteorites reign down upon Smallville.

Lex offers to protect Lana and have her flown to New York City, but she gets caught in the meteor shower ... Written by Shiro

season 4 was definitely one of my favorite season as it had a balance of a dark story and some light heartness than the previous season. during the season Lana is possessed by a 17th century witch, who ironically happens to be your ancestor. Clark on the other hand has refused to locate 3 kryptonian stones, as he just wishes to have a normal senior year, however when the countess,in Lana langs body, stands one the elements in Genevieve teagues blood, it triggers a meteor shower that forces Clark to act on his destiny, its also a consequence of clarks refusal to obey his father.

commencement is not just an episode that adds to the story, its also an episode we can relate too in terms of closing one chapter of our lives and opening another. commencement something we all go through as well as an episode that will leave you wondering what happens next, event if you already do.
