Revealing mistake: When the porter is dragged back onto the train at the start you can see (more obviously if you watch in slow motion) that there's absolutely nothing grabbing him, not even someone's shadow. (00:04:55)
Continuity mistake: At the beginning of the episode Buffy is thrown against a 'No Trespassing' sign and the sign is all crinkled, the vampire also punches it but later in the episode we see the same sign except that it looks brand new.
Visible crew/equipment: In the scene where the demons are attacking, one of the demons throws Buffy across a table. If you look carefully, you'll see the black mat which softens the stunt double's fall on the floor when she hits the ground.
Visible crew/equipment: When Harmony sits down opposite the operating table, behind her in the glass there is a reflection of a boom mike.
Audio problem: At the start of the episode when Buffy and Dawn are with Joyce in the hospital room, Dawn starts eating jelly, and when Joyce starts speaking you can see in the left hand corner of the screen Dawn talking, but no words are coming out.
Plot hole: When Buffy talks to Xander at the end and he tells her to stay with Riley, she mentions that he is going at midnight. But earlier in the episode, Riley doesn't tell Buffy he is going at midnight, he says "Transport's leaving tonight" first, and at the end of the conversation he says "Unless you give me a reason to stay, I'm leaving tonight". Nowhere in this episode does he tell Buffy that he's leaving at midnight.
Plot hole: How did Buffy know where to find Riley at the end of 'Into The Woods'? He told her he was leaving with the army, but he never mentioned the helicopter pad. (00:40:30)

Other mistake: According to Buffy's watch, the first scene with her, Dawn and Joyce starts at 4:23 PM and ends at 4:24 PM. But the scene lasts much longer than that.
Character mistake: Willow refers to the Tunguska Blast of 1917. However, that event actually occurred in 1908.
Visible crew/equipment: Buffy and the gang are in the waiting room after being told the cause of Joyce's death. After Willow asks "Why don't we sit down?" the camera pans from right to left and the camera focused on Dawn becomes visible at screen left. Some frames later it appears again as Dawn leaves to "pee" and the camera zooms out. (00:32:55)
Continuity mistake: When the gang are fighting Glory's minions, one of them knocks Giles to the ground and then tries to choke him. As Giles hits the ground he lands facing downwards so we can't see his face. But when the minion is chocking him in the shot immediately afterward, he is suddenly facing upwards.

Audio problem: When Spike arrives at the magic shop with a burning blanket over his head, he throws it to the ground and stomps on it, yelling, "Fire! Fire!" As he yells "Fire! Fire!" however, his lips aren't moving.
Visible crew/equipment: When Ben arrives in his car and discovers the Knights of Byzantium, the shadow of a camera on a crane can be seen in the bottom left corner of the screen as he pulls up.
Revealing mistake: When Spike, Xander, Anya and the Buffybot are attacked by vampires in the cemetery, the grass for the cemetery moves underneath the vampires' feet as if it were a carpet. The cemetery was a sound stage and not an actual cemetery.
Continuity mistake: The shape of the hole in the aluminium foil in the Winnebago's windshield changes shape several times throughout the course of the episode.

Revealing mistake: When Giles pushes Spike into the cabinet at the magic shop, you can see Spike's reflection in the glass of the cabinet's doors. But Spike is a vampire and therefore should have no reflection.
Continuity mistake: When Buffy, Dawn and Joyce say goodbye to Doctor Kriegel after being given Joyce's medication, the position of Dawn's hair changes between shots.
Chosen answer: He had larangitis and because of the shooting specifications they had to have him shoot the scene with a bad throat, they then re-recorded his lines and dubbed them. At various points during the scene and indeed the episode you can see him touch his throat or rub it.
