Buffy the Vampire Slayer/Recap/S4/E06 Wild at Heart

Veruca is revealed as a werewolf. Unlike Oz, however, she refuses to let herself be put in a cage.

Always a Bigger Fish / Bait and Switch: Appears to feature Spike as the Monster of the Week, but he gets captured by the Initiative and we don't see him until the next episode.
Audio Erotica: Veruca's singing enraptures the male Scoobies, especially Oz.
Berserk Button: Threaten Willow, and Oz won't restrain his wolf side.
Betty and Veronica
Beyond the Impossible

Buffy: Oz... You ok? And if it's possible, you seem more monosyllabic than usual.

Black Bra and Panties: Oz and Veruca are stealing clothes from a dorm's laundry. Veruca has changed into these, and isn't in a hurry to put on anything else while trying to seduce Oz.
Bond One-Liner: The vampire doesn't react to Buffy's Hurricane of Puns, much to her annoyance.

Thanks for the relocate. I perform better without an audience. You were thinking, what, a little helpless coed before bed? You know very well, you eat this late... (She stakes him.) You're gonna get heartburn. Get it? Heartburn? That's it? That's all I get? One lame-ass vamp with no appreciation for my painstakingly thought-out puns?

Burn, Baby, Burn: Averted; Willow is about to burn Oz's picture as part of the curse, but makes the mistake of looking at it first and so is unable to go through with it.
Cooldown Hug: Buffy holds a weeping Willow.
Diving Save: Buffy sees Willow (distraught over catching Oz and Veruca together) step into the path of a car without looking. She can't get to him in time, but fortuitously Riley Finn is there to yank her out of the way.
Failed Attempt At Drama: Spike's Big Bad speech is interrupted in mid-flow.
Fetish Fuel: Oz and Veruca have wild wolf sex in a cage.
Fully-Embraced Fiend / Shadow Archetype: Veruca to Oz.
Get Out!: Willow asks why Oz's plan to prevent Veruca going on a rampage involved the two of them being locked together in a cage all night.

Veruca: Girl's got a point.
Oz: (Angrily.) Leave.
Veruca: I'm just saying--
Oz: NOW!

Headbutt of Love: When Willow tearfully asks, "Don't you love me?" Oz vows "My whole life, I've never loved anything else," and gives her a textbook HBOL, complete with hug and kiss.
Hell-Bent for Leather: Willow dresses in leather pants when she goes to seduce Oz -- clearly she picked up some lessons from Faith.
I Have This Friend: Willow puts a 'hypothetical' question to Xander.

Willow: Well, say the girl's been noticing--
Xander: Will, I've deciphered your ingenious code.
Willow: Ok. Say I've been noticing Oz notice someone else. A woman.

Incredibly Lame Pun:

Buffy: Get it? Heartburn? That's it? That's all I get? One lame-ass vamp with no appreciation for my painstakingly thought-out puns?

- Get it? Painstakingly?
- Of course. This is Cringe Comedy.
I Need You to Shut Up: Oz tries to explain his actions with Veruca last night to Buffy, who cuts him off by saying coldly, "Now might be a good time for your trademark stoicism."
Love Before First Sight:

Veruca: I've wanted you even before I ever saw you. I sensed you. Did you sense me?

Love Makes You Crazy: A mild case, with Willow attempting a vengeance curse Oz and Veruca. She stops herself though. This time.
A Man Is Always Eager: That Oz is reluctant to engage in the physical act of love strikes fear into Willow's heart as a sign of infidelity. Xander lampshades it, saying she may have encountered "the seven annual minutes he's legitimately too preoccupied" to want sex.
Mugging the Monster: Buffy lets a vampire chase her to a part of the college with no witnesses.
Murder the Hypotenuse: Veruca tries to do this to Willow but Oz prevents it by killing Veruca.
Not So Stoic: Oz shows more emotion in this episode than in his entire series run.
Our Werewolves Are Different
Power Floats / Dramatic Shattering: The beakers Willow is using for the curse start to float in the air. When she stops the spell they drop to the floor and break.
Put on a Bus: Oz.
Security Blanket

Willow: The Bronze is nice and familiar. It's like a big comfy blanky.
Oz: I was under the impression that I was your big comfy blanky.
Willow: Aw, you're my my person blanky. This is my place blanky.

Slap Slap Kiss: Oz and Veruca meet in their wolf forms and immediately start to fight. They wake up naked in each other arms the next day.
Smells Sexy: Veruca taunts Willow by saying, "I know what you love. I have his scent on me right now."
Something Else Also Rises: Veruca brings up the wild wolf sex she had with Oz last night; her gaze flicks downward as she purrs "I know some part of you remembers that."
Talking in Your Sleep

Willow: Mm... It's in the sandblaster. Uh...
Oz: What's in the sandblaster, Will? It's a dream. Come back to me. (starts to fondle her under the covers)
Willow: Mmm...Hmm... All Geminis to the raspberry hats.
Oz: Now you're faking.

Tempting Fate: A notable Lampshading.

Buffy: (after killing a vampire) That's it? That's all I get? One lame-ass vamp with no appreciation for my painstakingly thought-out puns? I don't think the forces of darkness are even trying. I mean, you could make a little effort here, you know? Give me something to work with.
Spike: (watching her from a distance) Watch your mouth, little girl. You should know better than to tempt the fates that way. 'Cause the Big Bad is back. And this time, it's... (suddenly he's being tazered) Urrgh! Aaaahhh! (he is dragged away by commandos)

That Came Out Wrong

Buffy: I'm sure Oz is flogging and punishing himself...this is sounding wrong before I even finish.

This and That

Willow: What does it mean when a girl wants to... You know.
Xander: If you're doin' it, I think you should be able to say it.
Willow: Make love.

They Have the Scent: Buffy uses Oz to track Veruca, but she leads him off by dumping her clothes.
Transhuman Treachery: Veruca clearly sees humans as inferior and doesn't give a damn if she hurts or kills someone during her transformation.
Your Cheating Heart: The plot of the episode.
