In order to escape his father, Clark decides to use a kryptonite key to destroy his spaceship. When Clark puts the kryptonite key into the spaceship, Beck and his FX team tried to create a "virus/fungus" growth from the key slot to simulate "some sort of fractal decay". Mike McCormick worked specifically on the process of destroying the ship, giving the ship the appearance that it has a "nasty skin infection" that is spreading as if it is caught in the circulatory system. Next, Beck had to tackle the problem of the ship's final destruction. Originally, it was intended to have the ship explode, but no one wanted to have to rebuild the Kent farm. Instead, they settled on a giant EMP wave given off by the ship the moment it is destroyed. Entity FX created a beam of light that shot vertically up from the ship's location and then fell back down expanding into a "ripple that spread across the land". This beam of light would create a crater where the storm cellar was, which was dug prior to filming and digitally covered up so as to keep the illusion. One of the final shots of the episode was of Lex watching as his plane crashed into the ocean. In a homage to Robert Zemeckis's "Cast Away", Entity FX crafted a digital effect of the ocean water flooding Lex's plane as it hits the ocean. The scene is reminiscent of the same scene in "Cast Away" where Tom Hanks's character also watches as the ocean water floods his plane as he crash lands in the ocean.
