As Buffy's 17th birthday approaches all hell breaks lose. Spike tries to reassemble a demon known as The Judge, Jenny is revealed to be of the Gypsy clan that cursed Angel, and upon having sex with Buffy, Angel loses his soul.
Tropes:
Apocalypse How: The Judge will burn every being that is not evil.
Beautiful Dreamer: Giles and Angel share their last ever moment of true bonding when they gaze on a sleeping Buffy.
The Caligula: Drusilla's vampire mooks are clearly terrified of her manic moments.
Call Back: Buffy's dream has Willow saying about her monkey in French "The hippo stole his pants" referring to the animal crackers conversation she had with Oz in "What's My Line", plus Willow trying to teach Buffy French in "School Hard". The fact that Buffy doesn't know about the Oz/Willow talk is a sign it isn't just an ordinary dream.
Double Meaning: "Do you really think you're ready, Buffy?" has both a plot-meaning and a sexual meaning — is Buffy ready to lose her virginity, and is she ready for the terrible consequences of that act?
Dramatic Thunder: Thunder crashes when Angel wakes up in bed in pain as the curse is ripped from him.
Establishing Character Moment: The Judge's first act upon being reassembled is to burn all the goodness out of Spike's lackey, Dalton (therefore killing him), simply because he enjoys reading.
Evil Cripple: Spike is now confined to a wheelchair.
Evil Hand: The Scoobies recover the Judge's hand. It immediately tries to strangle Buffy.
Interrupted Declaration of Love: As he's about to depart on a ship, not to see Buffy for months or maybe forever, Angel starts to say he loves her when they're attacked by Dalton and his fellow vampires.
Lured Into A Trap: Subverted. Miss Calendar is ordered to "take Buffy from Angel" (to ensure Angel continues to suffer), and shortly later lures Buffy away from the school on a flimsy pretense, then leaves her to fight vampires. It turns out she was right outside the building where her surprise birthday party was; the vampires were not part of the plan.
Before they make love Angel says to Buffy, "I love you. I try not to, but I can't stop." Years later when another vampire tells her something similar, Buffy responds by punching him in the face.
The Mole: Jenny Calender was sent to Sunnydale to watch Angel.
Prophecy Twist: Buffy's dream seems to foretell Angel's death, but it actually means the death of his soul, allowing the return of Angelus.
Rule of Symbolism: Clear parallels are drawn between Buffy and Drusilla (it's even implied they're having the same prophetic dreams) as both end up releasing an evil force into the world.
Giles: Round robin? Willow: It's when everybody calls everybody else's mom and tells them they're staying at everyone's house. Buffy: Thus freeing us up for world saveage.
Spider-Sense: The Judge senses the presence of Angel and Buffy.
Take Me Instead: Buffy and Angel are caught by Spike and about to be killed by the Judge, Buffy first. Angel offers "Take me instead of her." Spike replies, "You're not clear on the concept, pal. There is no 'instead.' Just 'first' and 'second.'"
You Don't Want to Die a Virgin, Do You?: More along the lines of — we could die at any time, so let's take our relationship as far as it can go while we're both still alive.
You Have Failed Me: Averted; when Dalton looses the Judge's arm Drusilla is going to gouge out his eyes, but Spike convinces her it makes more sense to give him the opportunity to correct his mistake. He succeeds, but Spike and Drusilla give Dalton to the Judge anyway.
