Trivia: Martha makes a remark suggesting she thinks Bridgette Crosby and Dr Swan are together to which Bridgette comments "In another lifetime." Bridgette is played by Margot Kidder, who played the original Lois Lane, Prof Swan was played by the late Christopher Reeve. A nice touch I think.

Trivia: The Daily Planet article about Lionel Luther being found guilty was reported by Perry White. When Perry was seen in season 3, he was a disgraced reporter, after Lionel got him fired, who worked as a tabloid reporter. He vowed to get sober and get his career on track at the end of the episode "Perry." He isn't physically seen again until the end of season 9.
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.
