Clark bringing his father's dead body to the Fortress of Solitude. However, the scene was ultimately cut because, according to Gough, "It was something that sounded great on paper, but it felt like a bit of a stutter step in the episode." Gough later called the scene "morbid". Once the rough script was formulated it was sent to Gough and Millar for additional notes. Next, drafts were sent to the production studio and the network, who also made notes. Finally, Souders and Peterson re-wrote the episode; the script went through 10 drafts. The final version was finished "two-and-a-half [to] three weeks" before production began. Normally a script for a Smallville episode would go to about 40 different people, including "sets, props, and wardrobe", but because the episode featured the death of a major character, the production staff and writers kept it "top secret".

Filming Director Greg Beeman found shooting the episode difficult because he had recently lost his father; he noted, "I left from his funeral to go to Vancouver to direct the episode, so the emotions were very poignant for me." Souders stated that the production staff wanted the climactic scene of Lana's death to be a "big event". Originally, the show's producers wanted the car accident to be caused by a train. However, the show was not able to afford the special effects to pull the scene off, and so, the sequence was re-written to feature a bus crash. Souders noted that if the show had been unable to afford the bus wreck, it would have been re-written into a "little car wreck". The Lana's entire sequence death was choreographed by Christopher Sayour—series stunt coordinator and Welling's stunt double. Sayour described the scene as "important to me and important to a lot of people". The car crash sequence itself was actually a collage of several different shots. First, Kreuk was filmed driving a car on a process trailer with a mounted camera. A separate shot was filmed with a stunt double driving a lead car that was attached to a dummy car driving down a road at high speed. A bus was then driven in a perpendicular direction. The dummy car was attached with a detonator so that when the bus hit it, it would detach and not
