Factual error: While Clark is standing on the field of at Metropolis University at the end of the episode the shot pulls back to show the entire field. As it does there are two 50 yard lines visible as if he were on a Canadian football field, but Metropolis University is in Kansas.

Continuity: As Clark and Geoff are driving, the first shot of the SUV as it comes around the corner shows the ground is wet and the wipers are going. During their conversation the windows are constantly being rained on. Geoff points to the stadium and they arrive a few minutes later and as they drive into the garage you can see the street is dry.

Continuity: After Lois and Clark find out that Cooper dies, and after Lois leaves, while Clark and Geoff talk about how Lois is trouble Geoff hair keeps going from neat to slightly messed up. When the camera is behind Clark, Geoff's hair is all shaggy on the left side of his face. When the camera is behind Geoff, his hair is fixed so that the loose strands are tucked behind his left ear. These changes repeat throughout the scene.

Factual error: Clark finds Lois in the sewer and decides to use his heat vision to destroy the lock of the gate that is separating them. Clark uses his heat vision on the lock and the lock explodes, this is a very minor explosion. It also causes the door to fly off the hinges. Now the explosion from the lock is odd since heat vision causes things to melt and not explode, but Clark wasn't even using the heat vision on the hinges and they are destroyed. This is inconsistent with how his heat vision has been shown to work before.
