When Connor punches the young girl in Inside Out, a bruise is visible on her face, but when we see her lying dead after Cordelia kills her, the bruise is not there.

Julie Benz is credited as a “Special Guest Star” in the Angel episode Inside Out.

The title of the season four Angel episode Shiny Happy People is a reference to one of the hits from REM’s album Out of Time. The lyrics include the line, “Everyone around love them, love them” which echoes Jasmine’s message of peace.

Jasmine was a once higher being who manipulated herself into human form, using Cordelia and Connor as her parents. A seemingly beautiful woman, Jasmine gave those who came in contact with her a feeling of complete peace and serenity. She had the ability to control the minds and hearts of …

In Home, Lilah says to Angel, “Come on, Charlie. Let me show you around the Chocolate Factory.” This is a reference to Roald Dahl’s novel Charlie and The Chocolate Factory, in which a poor boy named Charlie wins a tour through the mysterious Willy Wonka’s chocolate factory, which ultimately leads …

Angel seemingly ‘kills’ Connor with a knife in Home, fulfilling the fake prophecy from season two in which it was said that “The father will kill the son”. He doesn’t really kill him though - Connor’s memories are erased and he’s sent to live with a new family.

The final episode to be written and directed by Tim Minear was Home. He left the show to work on Wonderfalls, which was unfortunately cancelled after only four episodes.

The scene of Connor’s happy new life in Home, in which he toasts his new family, is similar to the dream Angel had when he was underwater in Deep Down. The life Connor has now is the life Angel wanted for himself, his son and his colleagues.

In the DVD for Why We Fight, when Spike sings ‘God Save the King’, the subtitles incorrectly use the words to ‘God Save the Queen’.

Angel tells Spike they’re trapped at the bottom of the ocean in Why We Fight, when they’re in a submarine during WWII. In Tomorrow, Angel is again trapped in the bottom of the ocean, put there by his son Connor.

In Tomorrow, Connor tells Angel, “You’re the prince of lies”. In Why We Fight, we see a flashback to World War II, in which Angel is on a submarine with a vampire called the Prince of Lies.

In the flashback to World War II in Why We Fight, Spike objects to U.S. government experiments (”And I’m not getting experimented on by his government”) which is ironic as the government experimented with him in his later life. The US-based Initiative put a chip in his head to control …

You’re Welcome was the 100th episode of Angel to be made. The show was cancelled just 9 days after it aired. The episode finally dealt with the end of Cordelia’s storyline, including her death.

In the Angel episode Damage, new Slayer Dana begins to get memories of past Slayers. At one point she believes she’s Nikki Wood, the Slayer Spike killed in the 1970s. Her son, Robin became the Principal of Sunnydale High in Buffy’s season seven:

Spike: “Right. Let me explain. You got visions. …

The Angel episode Spin The Bottle continues where the previous episode ended, with Cordelia asking Angel “were we in love?” If you look at Angel’s face, the cuts and bruises that were present at the end of Supersymmetry are gone. You also see the cuts are gone in the ‘previously …
