Angel’s original depressing love metaphor was more extended in Happy Anniversary:

“Well, you know, love… it’s a fire. It burns you. Alive. Down to the bone. Then it turns the bone to ash and the cold wind just–”

Lorne says in Happy Anniversary, “This garden hue and the horns have kept me out of some key public performances - just once I’d love to ring in a Laker’s game with our national anthem.” He’s referencing the Los Angeles NBA team.

Angel originally took longer to discover the power source in The Thin Dead Line:

Angel: “How are you controlling them? Is it the entrails? I don’t think so. Could you be controlling them with a sacred Manari candle? Nah. Red Herring. I know, maybe it’s …

In The Thin Dead Line, Rondell says, “All right, look, all I’m saying is, you gotta let me get set up so they don’t see me with this [camcorder]. Cops see me with this and there’s no way we’re gonna Rodney King them.” He’s referring to a shocking incident …

In The Thin Dead Line, Cordelia says, “Maybe we could buy one of those star maps, find out where Steven Segal lives?” referring to the action movie star, who has starred in films including Today You Die, Belly of the Beast, The Foreigner, The Patriot, Under Siege, Hard to Kill …

The following line was deleted from Reprise:

Holland: “For a man who’s turned his back on his mission, you’re awfully scrappy. I do so admire that. No messy moral philosophy no guiding principles to muddle things. Just that pure, unpolluted human drive to win. You would have …

Cordelia says in Reprise, “Jeez, Wes, zip-a-dee-doo-dah, all right?” She’s referring to the Brer Rabbit tales which were worked into the 1946 Walt Disney musical Song of the South. the musical had the famous phrase, “Zip-a-dee-doo-dah” to express optimism.

Lorne says in Reprise, “Most anything that can manifest in order to move in this dimension can be killed. Kinda the downside to being here. Well, that and the so-called musicals of Andrew Lloyd Webber.”

The description of the first visit to the Sharp’s house was cut from Reprise:

Cordelia: “Um, will you give me the address again? The British guy drove last time and there were a lot of ‘Right side, Right side’ going on, so I don’t…”

We see Darla run Angel through with a sword in Reprise, but in the scenes where he and Darla make love there is no evidence of this wound.

A lot of Angel and Wesley’s discussion of the name of the agency in Epiphany was cut due to length.

Angel: “You kept the name. ‘Angel Investigations’.”
Wesley: “We’re going to change it. But if you must know, we felt we had as much right to it as you”.
Angel: “Oh. …

When Angel is leaving Wesley’s office at the end of Disharmony, you can see his reflection in the window of the door.

The ending of the original script for Disharmony ends with Wesley feeling a bit envious over the new clothes Angel brought for Cordelia:

Wesley: “I could use a DVD player”.

The WB promoted the Angel episode Disharmony, starring Harmony Kendall, with the tagline “Evil has never been so blond”.

In Disharmony, Cordy says “What am I, the bird lady of Alcatraz?” The 1962 movie The Birdman of Alcatraz, starring Burt Lancaster, told the true story of convict Robert Stroud. The multiple-murderer became fascinated by birds during one of his many terms in Alcatraz prison and wrote books on …
