What's worse than a crying child in a hospital with a bomb strapped to his chest?This week Smallville blesses us with possibly the season's worst villain. Garrett Davis is introduced as the little brother to a "rare liver disease" victim. Garrett's older brother ends up dying, but comes back to life the next day. Clark then investigates, deals with John's open-heart surgery and has to stop Garrett from blowing up the hospital (dope).
