Continuity: As Alicia holds the kryptonite on Clark her hand turns between shots. While she says ".but you broke the rules first." there is a camera change. Before the change the frontal view of Alicia has her holding the kryptonite with the glowing part straight up. After the camera change she is now holding it so it points to her left.

Continuity: The field trip is supposed to be on the 39th floor, as stated by Clark and the sign next to the elevator. The view outside the large windows as Lionel is talking shows that they are no more than 5 stories up.

Continuity: While Alicia is in Clark's bed she says "I know you wanted to kiss me, Clark." and while she says this her hand is on Clark's face. The very next shot shows her hand is nowhere near his face.

Continuity: After Adam says "Look who's talking." you can see Lana raise the notebook she found as she starts to respond when the camera is behind her. When the camera jumps to the other side, facing Lana, the notebook is down instantly between shots and she has to raise it up again.

Continuity: When Alicia confronts Lana in the Talon, when Alicia says, "you're definitely not smarter" Alicia has the knife right on Lana's cheek. When the camera switches to behind Lana, as Alicia says, "You don't have my abilities" the knife is not on her cheek.

Factual error: Clark and Alicia are in the basement of the school, as part of the plan to trick Alicia, and, as they go to leave, Alicia picks up her bag with Clark right next to her. A few minutes later we find out that Alicia has a kryptonite rock in her bag. She takes it out of her bag to get away from Clark. Clark felt no effects from the rock before that even though he was in such close proximity, and surely a bag would not be enough to protect his from feeling the effects.

Revealing: Earlier in the episode Lana is looking through Adam's journal which contains entries through at least the end of January. However, when Clark is taking Alicia home after their date, there are Christmas lights up due to filming during the holidays.
