The graduating kids’ parents didn’t exactly get a good view of the ceremony. Their seats were behind the stand where their children were sitting!

As Angel pulls the Mayor off Buffy in the hospital, you can briefly see his reflection in the glass of the room’s door.

When Angel uses the phone, you can see the reflection of his fingers and his shirt in the chrome plating of the phone.

As Angel carries Buffy through the hospital, we can see that Sarah Michelle Gellar is hanging on to his neck before realising she’s supposed to be unconscious and lets go.

In the shots when Kendra is leaving, there are two different angles of Kendra and Buffy talking. Kendra’s hair changes in each shot - sometimes her braid is in front of her shoulder and sometimes it’s behind.

There’s no hole in Angel’s hand when Buffy and Kendra carry him out of the church - even though he had a knife stuck in it by Spike earlier.

Spike’s stunt double can clearly be seen when he fights Buffy - and for some reason his face is very blue.

In the scene where Kendra and Buffy talk in Giles’ office, Buffy is sitting sharpening a curved knife. She puts the knife down, picks up stake, and begins to whittle the stake with the sharpener. In the next shot, the sharpener is replaced by the knife.

Xander slams a book on a bug. The book is a white biology textbook. However when the camera cuts to a shot of all of them standing around the table the book is gone, replaced by an old book with a red cover.

In the library, Cordy picks a worm from her hair then runs from the room. In one shot Kendra’s arms are behind her back, but in the next they’re folded in front of her.

When Patrice shoots Oz, the bullet should have gone right into his arm (from the angle at which she was shooting and the hole that appears on his arm) but he just gets scratched.

Only direct sunlight harms vampires - and it just kills them. Angel is seen being weakened by sunlight which is nowhere near him. This is strange as we’ve seen him with far more sunlight on him before and after this and he was fine then. He should easily be able …

When Buffy and Kendra fight, Kendra throws Buffy into a table and the table breaks. But in the next shot, the pieces are gone.

With his vampire strength, Angel should easily be able to smash through the tiny padlock which is locking him in the cage - but he doesn’t.

Cordelia leans on Buffy’s door frame with her left hand, but when we see Cordy from Xander’s point of view, she’s leaning with her right hand.
