up, helping her fight and kill the remaining vampires. Angel finally chops off the head of the lead demon. Kate walks away, saying that her father was human, and Angel doesn't know anything about that. Back in Angel's past, Darla finds that Angelus has killed all of his family. She reminds him that even though his father is dead, his memory will always haunt him. Kate visits her father's grave while Angel watches from the safety of the shadows. Production details When Liam rises from the grave, his breath (and Darla's) is clearly visible. Because vampires have no body heat, they are always at air temperature. Without a temperature differential, vapor cannot condense. Producer Tim Minear explains it was cold while they filmed this scene, shot on location at Hollywood Forever Cemetery behind Paramount Pictures, and there wasn't a large enough budget to remove the actors' breath digitally.
