Revealing mistake: When Lana throws a glass bottle at Lex (in the Talon) it smashes against the wall. But if you look closely Lana drops the bottle just before she throws it.
Continuity mistake: The lime slices on the side of Lex's and Amanda's drinks, in Club Zero, change position between shots.
Continuity mistake: As Lex is chalking his pool stick while talking to Dominic about cutting 20% of the workforce at the LutherCorp Smallville plant, there is a red snooker ball on the wall rack missing from the second row. When Lex walks over to the other end of the pool table, the camera shot changes back to Dominic, now there is a ball missing from the top row, which was not missing before.
Continuity mistake: While Clark and Jonathan are talking about Clark being on the football team, Jonathan puts his hands on Clark's shoulders. Between shots, the position of Jonathan's hands on Clark's shoulders repeatedly changes.
Continuity mistake: While Earl is in the hospital bed, his grip on the microphone to the waiting room changes from up to down and back. (00:17:55)
Plot hole: Chloe writes her phone number on Sean's hand. It disappears when we see him struggling against the ice of the lake, then reappears in the scene where he is calling old girlfriends. And how exactly would pen ink survive several hours submerged in water and then another eight hours of normal activity without becoming blurred? (00:04:15 - 00:19:50)
Revealing mistake: As Tyler slides across the floor, after Clark knocks him out of Whitney's father's room, he hits the camera. When he does the camera has a noticeable shake to it because of it.
Continuity mistake: At the beginning, when Seth picks up the barbell to beat Troy with, Troy is at the end of the locker room with the showers. As Pete and Clark show up, Troy is at the other end of the locker room.
Continuity mistake: When Chloe is first asking Pete and Clark the questions for her poll you can see that the top page on her clipboard is yellow. Then she shows it to Lana and the camera gives you a nice big shot of the front piece of paper and it is white. When Chloe says "its unleashing the inner Lana." the front of the clipboard is shown again and now the paper is yellow.
Continuity mistake: Tina's grip on Lana's necklace changes as she stands over Lana's body. (00:37:30)
Continuity mistake: While researching Greg with Chloe, Clark changes from one hand on the computer mouse to arms crossed and back. (00:34:00)
Factual error: Lana says the theme of her mother's prom was Saturday Night Fever, but she was in the class of 1977. Prom would take place sometime before graduation (which would be in May, maybe June), likely February or March. Filming for "Saturday Night Fever" didn't even begin until March 1977.
Revealing mistake: While Lana is listening to her Mother's graduation speech she reaches up to her neck for her meteor rock necklace. Her hands do not reach far enough back to unclasp the necklace yet the necklace comes off anyway.
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.
