Fear

Lana decides to use fear to control him, sure she liked sex, but this man ruined her father's life and she was going to ruin his. She got her red sun belt and kryptonite ring, along with some other items that'd be useful, like handcuffs that also have kryptonite in them, and some other kryptonite laced items, like whips, sticks, assorted sex and **** items, bullets, in the event she decided to just finish him. She also decided to add a dermal regenerator in the event she got hurt, or she did too much damage to Clark and wanted to keep him around. Just as she went to leave, she decided to bring some robots and other implements of destruction to lure Clark out, she may want to hurt him, but she wasn't going to take the time to look for him if she didn't need to.

Once she had finished with this, she went back in time to Smallville and sent the robots out to destroy the town. The robots started attacking the town, destroying and killing all in their path. Lana watched, waiting to see if Clark came to save his city.
