Continuity mistake: After Brian finds the note Alf left, we see William put the note under the microscope to inspect the tear drops. When William says "I'm going to go find him," he stands up and we see him leave the note on the microscope. When the camera cuts to William walking through the door, he all of a sudden has the note in his hand that was left on the microscope. (00:12:55 - 00:13:35)
Continuity mistake: In season one, episode two, "The Beauty Contest," Julia Sugarbaker states the following about her sister Suzanne becoming Miss Georgia World, 1976: "when she emerged from the isolation booth to answer the question, "What would you do to prevent war?" she spoke so eloquently of patriotism, battlefields and diamond tiaras, grown men wept." However, in this episode, Suzanne recalls her answer to the final question, "I said I wanted my own TV show." Further, the name of the pageant changes from Miss Georgia World to Miss Georgia U.S., and the year changed to 1975.
