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 conversation is a sign it isn't just an ordinary dream.
De-power: The Judge can't just 'zap' his victims as he's too weak after being reassembled; he must make physical contact to kill them.
Destination Defenestration: The Scoobies are hiding under the table waiting to pull their surprise party, when they hear fisticuffs outside, then Buffy and a vampire come crashing through the window.

Leitmotif: The Buffy/Angel love theme "Close Your Eyes" is heard for the first time.
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.
In her dream Buffy walks down a corridor of her home, then Drusilla suddenly appears behind her, blood dripping from her mouth. Later Buffy and Angel share a Held Gaze, only for Drusilla to appear in Game Face and dust him.
Angel announces that Drusilla intends to bring forth Armageddon. Cue Stunned Silence.
Must Not Die a Virgin: 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.
Never Found the Body: Buffy says that Drusilla could still be alive as they never saw the body after the events of "What's My Line?" This is a Series Continuity Error however, as vampires turn to dust when they're killed.
Not So Different: Buffy and Drusilla share the same birthday, appear in each others prophetic dreams, and both end up unleashing an evil force. And like Drusilla, Buffy forever loses her innocence once Angelus comes into her world.
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.
Pyro Maniac: The Judge's power "burns" the humanity out of his victims.
Real Dreams Are Weirder: When Buffy worries her dream of Angel's death will come true, Angel asks what else she dreamed about. Buffy admits she dreamt of opening an office supply warehouse in Las Vegas with Giles.
Red Herring: Neither the Judge or a revitalized Drusilla is the Big Bad the Scoobies need to fear.

"Transylvanian Concubine" by Rasputina, plays for Drusilla's birthday party.
Stealth Pun: Jenny staggers in with the box holding the Judge's arm. "Someone give me a hand."
Take Me Instead: Buffy and Angel are caught 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.'"
Talking in Your Dreams: Buffy finds out where Drusilla is hiding because she dreams confronting Drusilla at the factory. When Buffy goes there in person, Drusilla is quite pleased, saying, "I only dreamed you'd come."
Wet Sari Scene: Buffy ends up soaking wet after her escape from the Judge because it's pouring outside. Her shirt isn't see-through, but the scene ends with Buffy making love with Angel. The soaking aspect is used to underline Buffy's terror and vulnerability.
Wasn't That Fun?: Drusilla exclaims, "Do it again! Do it again!" after seeing the Judge burn up Dalton.
