Ep 12. Fracture

Smallville season 7 episode 12 titled "Fracture" picks up where the last episode left off, with Lana Lang (Kristin Kreuk) being saved from her supposedly fatal car crash. The episode begins with Lana being reunited with her friends and family at the hospital, but it's immediately clear that something is off about her. She is cold, distant, and unresponsive, which quickly alerts Clark Kent (Tom Welling) that something supernatural may be at play.

Clark soon discovers that Lana is harboring a dark secret: she has been possessed by a witch named Isobel (Erica Durance) who is seeking revenge against the Luthors, a powerful and corrupt family in Smallville. Isobel uses Lana's body as a vessel to carry out her mission, and Lana is unaware of what is happening to her.

Meanwhile, Chloe Sullivan (Allison Mack) is dealing with her own issues. She has been kidnapped by Lex Luthor (Michael Rosenbaum), who is using her as leverage to get information about Clark's true identity. Chloe is forced to use her skills as a journalist to outmaneuver Lex and protect Clark's secret.

As the episode progresses, Clark and his friends must work to save Lana from the witch's grasp while also evading Lex's grasp. The tension builds as the group races against time to stop Isobel from wreaking havoc on the town and uncovering Clark's secret identity.

Overall, "Fracture" is a thrilling and suspenseful episode that shows the strength of Clark and his friends as they face overwhelming odds. It also hints at the darker and more supernatural elements that the show will explore in later seasons, paving the way for some of Smallville's most memorable storylines.
