In this clip from the Smallville season eight finale, Cosmic Boy (Ryan Kennedy) of the Legion comes to tell Clark what he needs to do to get rid of Doomsday for good. Oh and he tells him he's going to die tomorrow.
In this clip from next week's Smallville, "Stiletto," We see Lois in her superhero costume where she calls herself Stiletto. In this scene, Clark calls her out on being Lois.
In this clip from this week's episode of Smallville, "Eternal," Tess attempts to blow up Davis' car. We're going out on a limb and saying this does not kill Doomsday.
Clark: Isn't it time we moved beyond these mental trials? Jor-El: Your determination is strong, Son, but just as your passion will be your greatest strength, so, too, will it be your greatest obstacle.
