Vortex (2) - S2-E1
Continuity mistake: When Clark and Lex are searching for Clark's dad, right after Clark gets mad at Lex and leaves it shows a head shot of Lex with the bandage over his left eye. In the beginning of the show he was injured over his right eye. (00:15:30)
Vortex (2) - S2-E1
Continuity mistake: Nixon raises the bar to kill Jonathan with a ridged side up, but when he is shot he is holding the smooth side up. (00:32:00)
Vortex (2) - S2-E1
Continuity mistake: When Martha Kent and Lana were talking about the meteor shower in the Talon Relief Center they sit down on the stairs. Lana puts both her hands on her knees. But in the next shot now her arms are outstretched in front of her, and now it's her elbows which are on her knees.
Vortex (2) - S2-E1
Continuity mistake: When Clark, Pete and Chloe were looking for Clark's father in the woods, Pete says: 'the twister must have dropped it here' and we see Chloe holding the map in her right hand. Cut to a different angle (as Clark runs towards the screen) and in the background we see Chloe holding the map with her left hand instead.
Vortex (2) - S2-E1
Continuity mistake: When Clark brings Lana to the hospital, a doctor attends to her and checks her vitals. In a close up we see the doctors right hand on Lana's neck checking her pulse and her left hand is no where in sight. Cut to a wider angle (as Clark runs away) but now the doctor is holding a flashlight in her right hand and her left hand is on Lana's forehead.
Vortex (2) - S2-E1
Continuity mistake: When Clark, Pete and Chloe were searching for Clark's father in the woods, they stumble upon a motor home dropped by the tornado. Chloe then picks up a Nixon's camera and looks at it. Cut to Nixon and Jonathan Kent then back to a wide shot as we see Chloe throwing the camera down onto the ground. Clark then uses his X-Ray vision once again. Cut back to a wider angle (as they walk away) yet we see Chloe throw down the camera once again.
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.
