Corrected entry: When Derek is shot and needs a transfusion, they first offer up Sarah as being O negative, the universal donor, but it is turned down as he needs his own blood type, AB positive. John then states, "Test mine," and his is magically AB even though his type could only be A, B or O with his mother as type O. To be AB, his mother would have had to have been A, B or AB. This was required to have John donate to Derek and to allow Sarah to offer as O-, but is factually impossible.kiskia
Corrected entry: As the scene begins, we are looking through Cameron's eyes as she holds up a photo of a night cityscape framed by plants. She lowers the photo to reveal she is standing in the exact spot that the picture was taken. In both the photo and her view, the plants that frame the distant city are very well lit. But the shot changes to show Cameron turning to face camera and we see the plants are now in near-total darkness beyond her.
Corrected entry: At the end of the pilot episode, just before Sarah, John and Cameron travel to the future, Sarah blasts Cromartie and you can see his head fly off. In this episode, Cameron reveals that Cromartie has traveled to the future along with them by pointing out his bare endoskeleton head in the background of the video that was taken of them just after they arrive in the future. It is supposed to be impossible for anything non-biological to time travel, so why is it that Cromartie's head made it through even though it was missing the surrounding living tissue?
Corrected entry: In the scene when Cromartie is talking to the "skin biologist" he has his face covered by a mask. When he asks him "Can you do it?" you can see the mask being blown from inside. This is impossible, because Cromatrie has no flesh, furthermore he has no lungs to breathe. In all other scenes his mask is still.
