You can clearly see Willow and Buffy’s stunt doubles as Buffy dives after Willow and falls on her.

When Willow drains Rack, she holds his face with her right hand. This changes to her left in the next shot. The hands then alternate for a while.

When Xander is hugging Willow at the end of the episode, his knee changes position in different shots.

You can see the cables holding up the temple, though you may need to zoom in on your DVD so see them clearly. The cables can be seen to the right of the temple.

After Giles first knocks Willow down, her nose is bleeding. As the camera switches between the two of them the blood keeps disappearing and reappearing.

Why is Katrina in Sunnydale again? She doesn’t live there, and was only there in I Was Made to Love You as she was staying with Warren for Spring Break.

When Warren is talking at the beginning of the episode about the cerebral dampener, there is a piece of hair hanging down on his forehead. In the next shot the hair has gone, without Warren moving.

Why was the drive-through intercom still on when Willow goes to find Buffy? And why is Willow’s voice broadcast over the entire restaurant?

When Invisible Buffy talks to Dawn in the kitchen, there is a pan on the stove which disappears then appears again.

While on the computer in the Social Sevices office Buffy types “All work and no play makes Doris a dull girl”. We see the ‘B’ and ‘F’ keys being pressed, though those letters are not used in any of these words. She also doesn’t press the ‘A’ key.

There are sun rays on Spike in the kitchen yet he doesn’t burn.

When Amy became a rat in Gingerbread she had only really dabbled in magic previously. When she is de-ratted in this episode she is a complete addict and introduces Willow to Rack (who she must have met when she was still in school). This seems to be an unlikely shift …

When she’s in the kitchen in the morning, Dawn’s hair moves from before to behind her shoulders in different shots without her touching it. This occurs again when she says, “So, what’s the big bad - should we be worried?”

At the start of Wrecked, when Spike grabs Buffy and pulls her down onto him, you can clearly see the flesh-coloured pants he is wearing.

Andrew claims to have seen every episode of Doctor Who. However, over 100 episodes of Doctor Who have been missing from the BBC archives since before he was born. Considering he’s a complete nerd, Andrew would have known this and commented on it.
