MUSIC CUE: "Happy" by Pharell Williams, Despicable Me 2 soundtrack.
Sherlock is in the living room, seemingly asleep on the couch, her legs perfectly straight and her arms out at odd angles.
But it turns out, she's not actually asleep. With her eyes still closed, she sticks out her right hand, which was dangling from the couch, and reaches for something on a nearby coffee table, and then slaps something on her left arm. She then "falls asleep" again.
This fades to an overhead close-up shot of Sherlock jolting awake. Joon walks in as Sherlock starts waving her hands in front of her own face. It almost looks as if she's imitating the hand movements in Madonna's "Vogue" video or the ones in in The Hillywood Show's Lady Gaga Christmas Special parody.

Joon: What're you doing? Impersonating Madonna? Or Lady Gaga?

Sherlock: Smiley face sticker.

She lifts up her left sleeve to reveal what she'd slapped on herself: Three large smiley face stickers.

Sherlock: Helps me think. It's impossible to sustain a Taco Bell habit on each semester-long meal plan budget. Bad news for brain work.

Joon: It's good news for healthy food.

Sherlock: Oh! Healthy food. Healthy food is boring.

Joon: Why do you have three stickers? And what do they have to do with tacos?

Sherlock: It's a three-sticker problem. And haven't you heard that "Happy" song by Pharrell?

Joon: OK... (A beat as she's ignored by Sherlock, then:) Well...? (Another beat, then:) You asked me to come. I'm assuming it's important?

Sherlock thinks a moment.

Sherlock: Oh, yeah! Of course! Can I borrow your phone?

JOON

My phone?!

Sherlock: I don't want to use mine. Always a chance someone'll recognize it. It's on my blog.

Joon: Anthea's got a phone. You know, our neighbor? Your old RA? You could've asked her before she ran off to class. Or, don't we have a land line?

Sherlock: She wasn't there. She must've been in another class or something. And, really, who uses land lines anymore, even if we do technically have one?

Joon: Yeah, or something... Anyway, I was on the other side of campus!

Sherlock: There was no hurry.

Joon: You just said it was important!

Sherlock sticks out her hand. Joon sighs, pulls the phone out of her pocket, and passes it over.

Joon: So, what's this about? The case?

Sherlock: Her case.

Joon: Her case?

Sherlock: Her suitcase, yes, obviously. The kidnapper took the suitcase with her in the act. First big mistake. With the others, it just looked like the other girls forgot to show up.

Joon: OK. The suitcase was taken. So?

Sherlock: It's no use. There's no other way. We'll have to risk it. On the mantle, under the skull, there's a number. I want you to send a text.

She tries to pass Joon's phone back to her. Joon, however, doesn't bite quite yet.

Joon: You brought me all the way over here... to send a text message?!

Sherlock: Text, yes. The number under Piper the Skull.

Joon reluctantly takes her phone back, but doesn't go to get the phone number.

Joon: The skull's name is Piper?

Sherlock: Don't ask.

Joon shifts awkwardly, still not going to get the number.

Sherlock: What's up?

Joon: I just met a friend of yours?

Sherlock: (Confused:) A friend?

Joon: An enemy.

Sherlock: Oh, OK. Which one?

Joon: Well, your archenemy, according to her. Do people even have archenemies?

Sherlock: Did she offer you money to spy on me?

Joon: Yes.

Sherlock: Did you take it?

Joon: Hell no!

Sherlock: Pity. We could've split it. Think it through next time.

Joon: Who is she?

Sherlock: The most dangerous woman you'll ever meet, and currently, not my problem. Under the skull. The phone number.

Joon: OK, fine.

She goes over to get it.

Joon: Jennifer Wilson. That was... Hang on. Isn't that the kidnapped freshman?

Sherlock: Yes, but it's not important. Just text the number.

Joon starts to, slowly.

Sherlock: Are you doing it?

Joon: Yes.

Sherlock: Have you done it?

Joon: Slow down, woman! God!

Sherlock: Text these words exactly: "What happened at the McDonald's at University Mall? I must have blacked out. Please meet me at University Mall."

As Sherlock dictates the message and Joon types it, we see the words come up as a small title, like the ones used previously for other messages.

Joon pauses the text.

Joon: You blacked out?

Sherlock: What? No, no.

Sherlock jumps off the couch. She walks up over the table, temporarily disappearing into the hall. Joon finishes the message.

Sherlock: Type and send it. Quickly.

She comes back with a pink suitcase.

Joon: What's the restaurant?

Sherlock: McDonald's. Hurry!

Sherlock sets the suitcase on a chair and zips it open. She sits down in another chair next to it. Joon finishes the message and sends it, turning towards Sherlock.

Joon: That's... That's the pink freshman's suitcase. That's Jennifer Wilson's suitcase?

Sherlock: Yes. Obviously.

There's a slight awkward pause.

Sherlock: Oh, maybe I should mention that I didn't kidnap her.

Joon: I never said you did.

Sherlock: Why not? Given the text I just had you send and the fact that I have her suitcase, that's a perfectly logical assumption.

Joon: Do people usually assume you're the villain?

Sherlock: Sometimes, yeah.

She jumps up onto her chair, sitting on her feet.

Joon: OK...

Joon sits on a third chair.

Joon: How did you get this?

Sherlock: By looking.

Joon: Where?

Sherlock: The kidnapper must've taken her to the Giant at University Mall yesterday evening or early this morning. Nobody could be seen with this case without drawing attention themselves, not after move-in weekend. So, obviously, they'd feel more likely to get rid of it. Wouldn't have taken more than five minutes to realize the mistake. (Over footage of Sherlock rolling the suitcase away from the dumpster at Southside:) I checked all the dumpsters on-campus, and oddly enough, it was right near where we started, on the other side of Essex Hall from Dickenson Hall. It was in the one that Southside uses for their waste.

The scene returns to the living room.

Joon: Pink. You got all that because you realized that the suitcase would be pink?

Sherlock: It had to be pink. Obviously.

Joon: Why didn't I think of that?

Sherlock: Because you're an idiot.

Joon: What? Hey!

Sherlock: No, no. Don't look at me like that. Practically everyone is. Now look. Do you see what's missing?

Joon: From the suitcase? How could I?

Sherlock: Her phone! Where's her cell phone? There was no phone at the crime scene, there's no phone in the suitcase... We know she had one. You just texted it.

Joon: Maybe she left it in her dorm room? You said you could see there was still stuff on both sides of the room from outside the window...

Sherlock: Oh, come on. She's a college student. College students are obsessed with technology. She'd never leave it in her room.

Joon: Oh. Yeah. Wait, why did I just send that text?

Sherlock: Well, the question is, where is the phone now?

Joon: She could've lost it?

Sherlock: Yes, or...?

Joon: The kidnapper. You think the kidnapper has the phone...?

Sherlock: Maybe the kidnapper took it from her to keep her from calling for help. Or the kidnapper took it out of her suitcase. Either way, the kidnapper probably has it.

Joon: Sorry... What are we doing? Did I just text a kidnapper? What good will that do?

Joon's phone rings. She picks it up off the arm of the chair she's in.

Sherlock: A few hours after this last girl, and now the kidnapper receives a text that can only be from her. If somebody just found that phone, they'd ignore a text like that. But the kidnapper would panic.

She slams the suitcase shut and gets up.

Joon: Have you talked to those girls from earlier?

Sherlock: Four girls have been kidnapped. There's no time to talk to criminology students.

Joon: So why are you talking to me?

Sherlock: The skull never answers.

Joon: So, I'm basically filling in for your skull?

Sherlock: Chill. You're doing great. Well?

Joon: Well, what?

Sherlock: Well, you could just go to class... Or do homework...

Joon: You want me to come with you?

Sherlock: I like company when I go out, and I think better when I talk out loud. The skull just attracts attention, and it gets boring pretending I'm a theater student rehearsing for Hamlet all the time... And it looks suspicious, because the theater department obviously doesn't do just one play a year...

Joon laughs.

Sherlock:What? Is there a problem?

Joon: Yeah. Sally Donovan.

Sherlock: What about her?

Joon: She said that you'd get off on this, that you'd enjoy it.

Sherlock: And I said it'd be dangerous, but here you are. Come on.

She exits the house. Joon sits there a moment, and then gets up to follow Sherlock.

Joon: Dammit, woman!
