Corrected entry: When Buffy woke up after Dracula had bitten her, the scar was on the wrong side of her neck.
Corrected entry: In this episode Willow and Giles are scanning texts into the computer. Why don't either of them, especially Willow, remember the first season episode "I robot. You Jane" where they did this and a demon manifested into the Internet and then into robot form?
Correction: I'm sure that they did remember it. That was, however, a special case where a demon had been trapped inside a book - because of that very incident, we can be certain that Giles would have taken special care to ensure that the books that they were scanning were demon-free.
Correction: We are shown Buffy looking at the scar in her bathroom mirror, causing it to flip to the other side. It is in fact on the correct side throughout the rest of the episode.
