Primeval (2) - S4-E21

Plot hole: Willow hacks into The Initiative's computer system and discovers air ducts and electrical conduits leading to Adam behind 314, but the room doesn't show up on the schematic. It seems unlikely that nobody who didn't know about Adam would have noticed this and investigated.

Graduation Day (1) - S3-E21

Plot hole: Healing Angel requires draining the blood of a Slayer. Buffy tries to kill Faith in order to get some of her blood but Faith gets away after Buffy stabs her at the end of "Graduation Day Part 1." The amount of blood on the dagger that she used wouldn't be enough blood to heal Angel, but it'd be a start. So why didn't Buffy just use some of the blood on the dagger? In the very first shot of "Graduation Day Part 2" we see the dagger coated with the stuff.

Life Serial - S6-E5

Plot hole: In the 3rd time loop at the magic shop, the woman looking for the mummy hand looks surprised when Buffy knows what she wants. In the 2nd time loop, the woman tells Buffy that she called the shop 20 minutes earlier and was told that they had one. Therefore at least one of the shop's staff would be aware that a woman would be arriving looking for a mummy hand.

Something Blue - S4-E9

Plot hole: Before the opening credits where Buffy stakes the vampire in the cemetery, she stakes him below the left shoulder, above the heart. Yet he still turns to dust and dies.

Bad Girls - S3-E14

Plot hole: Buffy saves Angel from Balthazar by dropping a light into the tub of water that he's sitting in. But why would the tub have been put directly underneath a light? Balthazar was being kept alive throughout the episode, wouldn't having a light above him be a bit unwise?

THGhost

Helpless - S3-E12

Plot hole: When Buffy enters the house to rescue her mother she uses a stake to stop the front door from closing. A vampire then grabs it and the door closes. Why did Buffy use a stake knowing that there was a vampire there when she was almost killed by a vampire with her own stake earlier in the episode because Giles had been injecting her with a muscle relaxant?
