When Adam arrives at the Trager's house, Stephen and Nicole are surprised about his resemblance to Kyle. This makes no sense because ever since Kyle saw the picture of Adam at U-Dub, they all discussed how Kyle and Adam looked exactly alike.
When Kyle is sleep-walking in the kitchen, he tells Stephen and Nicole that he's "out of wavelength 640-750 nanometers" which means that he's out of red. However, the entire visible spectrum is only about 300-350 nanometers wide, and the 110-nanometer band that he claims to need would range from the beginning of the red spectrum all the way to infrared. A much more likely wavelength band for the red that he needs would be something along the lines of 670-690 nanometers, a much smaller and more single-color specific wavelength band.
