Continuity: As Morgan Edge hands Lionel the bag with the mason jar of blood the camera is on Lionel's side and bag has a very neatly folded flap to keep the top closed. As Lionel takes the bag, while the camera is on Edge's side, the opening is wrinkled and not folded shut as it was before.

Factual error: While Clark is inside the semi-truck being delivered to Morgan Edge and Lionel Luthor he manages to remove the kryponite apparently duct taped to his chest. This cannot be possible since he even a small piece of kryptonite (Lana's necklace) was enough for him to trip and fall from several feet away! Imagine a larger chunk like the one they strapped to his chest. He should have been severely weakened by it and the radiation should go through anything in that truck besides lead and the tape used to secure the rock on Clark's chest is not made of lead. His ability to not only have the strength to rip the taped rock off his chest but to then launch it to the far side of the truck should not be possible in view of the nearly immobilizing effects kryptonite has on Clark.

Continuity: When Clark and Jonathan return home, Jonathan collapses on the couch. It shows Clark rushing to his side. But in the next shot where it shows Martha's reaction, you can see Clark rushing to his side again.

Plot hole: When Edge needs the vial of Clark's blood back, Edge holds Clark's parents hostage. Clark decides to use a sharp piece of kryptonite rock to cut his skin and give Edge a new sample. When Clark picks it up, and when he places the kryptonite rock on his skin, he shows no sign of the usual affects of the rock which include the green lines radiating up his arms.

Continuity: When Lex pulls the gun on Linoel, when the camera is on Lex he is pointing the gun in Lionel's face. When the camera is on Lionel, Lex is pointing the gun in Lionel's chest.
