- Angel is angry that Spike got a soul and only angsted for a week while he has been suffering for over a century. This is because of how they got their souls. Spike went and had his soul magically implanted back into him. Angel was cursed with his soul so that he would forever be tormented by all he had done. It is virtually impossible for Angel to ever truly process and move on because the curse locks him into feeling like he can never atone for his crimes.
- Holtz is specifically mentioned to be hellbound upon his death. So where was he when LA went to Hell?!
- If you just watch Buffy, you have to how the world has lasted this long, given that The End of the World as We Know It always seems imminent...then you watch Angel, and find out that Wolfram and Hart are behind almost every evil thing on either show, and they don't want to win, meaning that all of Buffy's enemies are being played for suckers.
- Cordelia telling Fred to shut up near the beginning of Fredless seems kind of mean at first, until you remember that the rest of the Fang Gang (especially Wes, Cordy, and Gunn) pretty much communicate in snark and insults. And since the rest of this episode is spent firmly establishing Fred as a permanent part of the team, Cordy's "Shut up, Fred," could actually be interpreted as an early indication that she's accepted Fred into their group, to the point where Cordy's comfortable being snarky towards her.
- Illyria wonders at the Wolf, Ram and Hart being such a powerful entity when in her time they were little more than a joke. This is explained enough by the absence of Old Ones on Earth that lowers the bar considerably, but it could also come from the fact that the Senior Partners thrive on the evil in every human. Since humans now dominate Earth, this would give the Senior Partners that much more power.
- Angel's evil and soulless alter ego is called Angelus, the series is set in the city of Los Angeles. All of them different translations of Angel. But given the film noir set up of the show, Angel knows that as long as he remains in that city, helping the helpless, his dark side will always be there, and all around him (as there are always people around, and he is still a vampire, and even with a soul he still has to fight his bloodlust daily). And as Wolfram and Hart reminded him, evil will always exist there.
- Angel singing "Mandy" in his first karaoke at Lorne's club becomes pretty sade when you listen to the actual lyrics of Mandy. http://www.azlyrics.com/lyrics/barrymanilow/mandy.html Sound like a certain vampire's relationship to a certain slayer...and later on to a certain brunette named Cordelia.
- In the very first episode, Doyle tells Angel: "I come in uninvited, so you know Iím not a vampire like yourself." The thing is, that rule doesn't apply to demon lairs... and Doyle is himself a demon. The reason Doyle didn't know the rule is because he looks human, and no vamps would attempt to test the demon-lair rule on him because they're screwed if they're wrong. This line wasn't just a throwaway As You Know informing new viewers that vampires Must Be Invited, it was also establishing a tiny bit of Doyle's character!
- Wesley figures out, with only minimal clues, that Bethany was molested by her father. It begs the question, how did he manage to catch what the others so easily missed? We already know that Wesley suffered emotional (and possibly physical) abuse at the hands of his own father, but the speed and accuracy with which he deduces Bethany's past makes you wonder what else may have been done to him.
