Trivia: The asylum to which Lex is taken at the end of the episode is called "Belle Reve," which is French for "beautiful dream." It is also the name of the family mansion that once belonged to Blanche and Stella DuBois in "A Streetcar Named Desire." The mansion was lost, but it was the one memory to which Blanche clinged throughout her descent into madness. Belle Reve is also home to many lesser powered super villains in the DC universe, including some of Superman's enemies.
Trivia: Michael McKean, who guest stars as Perry White, is married to Annette O'Toole, who plays Martha Kent.
Trivia: When at Molly's, Lex tells Clark she sent another email and asks if Clark recognized it, which belongs to Martha Kent. The email address is "CNH320@instamail.org." CNH 320 was the license plate number of the General Lee in "The Dukes of Hazzard" (which stars John Schneider who plays Johnathan Kent).
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.
