Revealing mistake: Clark uses his heat vision to warm up Alicia's cup of hot chocolate. When the drink is hot enough to start giving off steam, the "steam" is not water vapor. Water vapor would be nearly clear and rise straight up from the cup. This "steam" is more likely from a piece of dry ice as the vapor is rolling over the side.

Other mistake: Lois digs up Chloe's grave site to unearth her casket. It is obvious that the casket is not buried six feet deep. You would think, with all that is going on, that LuthorCorp would have at least buried the casket deeper to deter inquisitive eyes and maybe throw in a few scattered bones for good measure.

Question: The WB said that Smallville was going to introduce Krypto the dog. What is Krypto's origin and how did he get his powers?
Answer: In the comics, Krypto is a dog from Krypton who was used as the passenger in a test launch by Jor-El, Superman's father, before he launched the actual rocket taking his infant son to Earth. Krypto's capsule was involved in a mishap, sending it out of Kryptonian orbit and eventually found its way to Earth where he linked up with the young Clark Kent. Like any native of Krypton, Krypto has superpowers on Earth. In Smallville, the dog is a standard Earth dog who has been experimentally injected with kryptonite, giving him super-strength for a limited period of time, who escapes and links up with Clark (who suggests the name Krypto, ostensibly because of the dog's cryptic origins). It doesn't take too long for the dog's strength to fade, and the Kents decide to keep him, although they ultimately name him Shelby, after a dog that Martha Kent had in childhood.
