Jasmine takes her name from the night-blooming jasmine she smells growing at the Hyperion. Two years ago, in "The Trial," Darla also referred to the smell of the flower, which reinforces the idea that the Jasmine arc began in season two with that episode.
Gunn's Grandmother's name is Helen.
When Angel stakes a vamp it turns to dust before the stake even touches it.
Angel: They don't understand.
Angel: We don't want to kill her. We just... want to find her, so we can worship her.
Gunn: Okay, so what are we dealing with?
Fred: Eight legs? Three heads? Horns?
Fred: No offense.
Connor: Two legs, one head, no horns.
Lorne: Lemme guess, green?
Angel: No. Kind of... mocha.
Lorne: My God.
Jasmine: People keep saying that.
Lorne: One does tend to let the housekeeping slide during an apocalypta-lite.
Lorne: Oh well, I'm as tickled as... someone so tickled they're all out of similes.
Fred: (holds up sweater) What do you think?
Wesley: I think it looks brand new.
Fred: (crying) It is!
Fred: You don't have a name!
Cordelia's Offspring: No
Fred: You should have a name!!
Counter Guy: Looks like you just lost your best friend.
Fred: All of them...
Connor: You always told me to clean up after myself. I was just putting it away.
Fred: Okay... are you still evilish, 'cause...
Fred: There's been a lot of dismembering going on in that basement. If you know what I mean.
Lorne: Well, it's been a busy month.
Gunn: Clorox, she bleaches away the hate.
Lorne: It's like a hard day's night out there.
"Hard Day's Night" was a song and a movie by the poular British group The Beatles. In the movie, the band has girls chasing them much like everyone is following Jasmine, and the song is about everything being alright, which is Jasmine's promise.
An in-joke reference to the '74 flick I Dismembered Mama, a really bad cut-em-up gore movie in the spirit of Texas Chainsaw Massacre. In turn its title was a play on the '48 flick I Remember Mama.
Title: Shiny Happy People
"Shiny Happy People" was the title of one of the biggest hits from REM's album "Out of Time".
The lyrics include "Everyone around love them, love them" which seems to echo Jasmine's "message".
Interestingly the lyrics also feature "There's no time to cry /Happy happy". It's just after Fred breaks down in tears that the "happy people" spell is broken.
