Synopsis by Brian J. Dillard
Three months after Angel (David Boreanaz) and Cordelia (Charisma Carpenter) vanished (see "Tomorrow"), Fred (Amy Acker) and Gunn (J. August Richards) try to hold down the fort. None of their research into the twin disappearances yields any results -- not even a phone call to old ally Lorne (Andy Hallett), who seems preoccupied with his new gig as a Vegas lounge singer (see "The House Always Wins"). Unaware that Connor (Vincent Kartheiser) banished Angel to the bottom of the sea, Gunn and Fred care for the troubled teen as if he were their own. But Wesley (Alexis Denisof), despite his perverse sexual relationship with evil lawyer Lilah Morgan (Stephanie Romanov), continues to research Angel's disappearance -- with a little help from Justine (Laurel Holloman), Connor's accomplice, who is now Wesley's prisoner. Wes rescues Angel from his watery tomb and even proffers some of his own blood to help rouse his starving, hallucinating former boss. Then it's truth time for Connor, who faces Fred and Gunn's wrath and gets booted out of the nest by his loving but betrayed father. Meanwhile, Lilah stays ahead of the competition at Wolfram & Hart, and Cordelia, having ascended to a higher plane of being, is bored out of her skull. Originally broadcast Oct. 6, 2002, on the WB network, "Deep Down" marked the fourth season premiere of the supernatural comedy drama. Starting with this episode, previous guest star Vincent Kartheiser joins the regular cast as Angel's troubled teen son, Connor.
