The season finale required numerous computer-generated imagery. At the start of the episode, Jor-El's disembodied voice talks to Clark through the spaceship. For this scene, Entity FX created a completely computer-generated model of the ship, because the ship had to transform into multiple objects as the scene progressed, creating it digitally was the best option. Later in the episode, when Clark refuses to leave Smallville, Jor-El brands him with a Kryptonian tattoo. Brian Harding worked on the tattoo that is placed on Clark's chest, creating an effect based on the idea that it appeared to burn from the inside. For the same scene, Beck and his team had to digitally create a bare chest for Welling's stunt double, who had to wear a shirt to hide the safety harness he was wearing when they dropped him in the moment Clark is released from the ship's hold.
