Synopsis by Brian J. Dillard
As Angel (David Boreanaz) makes up his mind to protect rather than kill the unborn child he sired with Darla (Julie Benz), flashbacks chronicle the enjoyment the former lovers derived from killing the wife and family of Holtz (Keith Szarabajka). Back in the present, Holtz materializes -- the result of a pact with the demon Sahjhan (Jack Conley) to allow the vampire-hunter to travel through time and once again pursue Angel just when he's at his most vulnerable. Meanwhile, Lilah Morgan (Stephanie Romanov) learns of Darla's pregnancy thanks to the surveillance equipment Gavin Park (Daniel Dae Kim) secretly installed in Angel's hotel. As Wolfram & Hart mobilizes to attack Angel and Darla, the gang sneak into a hospital and find out that Darla's child is both human and male. A large group of vampires arrives -- cultists who want to worship the unborn baby but kill everyone else, including his mother. The gang escape and head back to the hotel to grab some things and hit the road, unaware that Holtz is waiting inside for Angel. Just then, Darla goes into labor in earnest. Originally broadcast November 12, 2001, on the WB network, "Quickening" marked season three, episode eight of the supernatural comedy drama. The second installment in a four-part sequence, the story line continues in "Lullaby."
