At David Nabbit’s party in War Zone we hear “Para Lennon & McCartney” by A Friend From Rio.

Madam Dorian’s is a brothel staffed by demon prostitutes, located in Bel Air. Angel visited there in War Zone to question Lina over photos taken of David Nabbit there. As we see increasingly in Angel - humans and demons mix more frequently and publicly than in Buffy.

When Cordelia is bandaging Angel up in War Zone, the wound on his had that he got when he stopped the crossbow arrow has disappeared.

The character of Gunn is introduced in the following way in the script for War Zone:
We start in low and see a pair of black leather boots walk into frame. We move up to reveal black leather pants and the bottom of a black coat. We move further …

When Cordelia is looking for information on Vanessa online at the beginning of Blind Date, she has a pink note stuck on her computer. This appears and disappears in different shots.

We discover from Lindsay more about the elaborate security in the Wolfrasm & Hart offices in Blind Date - they have a Pregotthian demon guarding their vault; red-robed shamans who can tell when a vampire is in the building; and mind readers instead of drug testing.

Just before Angel kills Vocah he takes his mask off, but when Vocah falls down dead you can see the mask is still attached to his face.

Many changes were made to the scene in To Shanshu in L.A with Cordelia, Wesley and the donut, including cutting this exchange:
Wesley: “The end… death… what if the root was proto-Anatolian, say from the Hittite… if it’s Hittite, the root is really more like… close”
Cordy: “Clothes? As in Armani …

In To Shanshu in L.A, Cordelia is disabled to near madness when she is shown continuous visions of suffering people by the demon Vocah. After she’s saved by Angel and Wesley, Cordy’s outlook on life completely changes, and her determination to help those she’s seen suffering begins in earnest.

Vocah was summoned by Wolfram & Hart to perform a ritual using the scroll of Aberjian to resurrect Darla, as well as ensuring that Angel’s ties with the Powers That be were destroyed. His maggot-ridden face was obscured by a bronzed mask, and he wore a long cape. Vocah killed …

Ryan Anderson was a human boy who became possessed by an Ethros demon. Angel exorcised the demon out of him, supposedly making Ryan normal again, but when he spoke to the demon, Angel discovered that the boy had no conscious at all, and the demon had in fact become trapped …
