Zack: Why did Angela just leave with Booth?
Booth: That wasn't me. That was "Mmmm Angel, the sexy vampire."
Zack: Oh, yeah, I should have recognized the coat. (incredulously) You think he's sexy?
Booth glares at Zack.

Brennan: Zack is going to take a look at the trace results, and will call Hodgins for help if necessary. I'm about ready to leave.
Cam: I have an appointment to get to this morning (quickly glances at Booth and leaves the lab).

Booth and Brennan go downstairs and out of the building, Cam is watching them from the lobby, hidden from their view.

Booth: I need a nap before I start talking to the suspects and tracking down witnesses.
Brennan; I'm coming with you.
Booth: That's not exactly the kind of "nap" I had in mind, but OK, why not? What happens in LA, stays in LA.
She smacks him playfully.
Booth: How about breakfast first? We've got your convertible, right? I saw a drive-in diner near the hotel. It'll be fun!
Brennan: What's this thing you have about convertibles?
Booth: I'm a guy. I like it with the top down.

They get in the car and drive off. Booth's phone rings.
Booth: Booth... I didn't expect to hear from you this-- ... OK, I'll be back at the hotel in a little while and I'll come by.

At the drive-in diner

Booth: Isn't this just the way to go? In the convertible, having breakfast, sun shining on your face.
Brennan: Unless you're a vampire.
Booth: You always have to ruin the thought, don't you.
Brennan: I'm kind of worried about Angela with Angel.
Booth: Because he's a vampire? Or you're worried they're not using protection? After a couple hundred years he's bound to have something communicable.
Brennan: That story they were telling us about the curse? What if he loses his soul and goes evil and hurts her?
Booth: Nah, that's just meaningless sex, Bones. It never leads to happiness. It's not supposed to. (He gets a thoughtful look on his face) Enormous pleasure, maybe, but happiness, no. She won't get hurt unless she expects more from him than that.
Brennan: So, what is perfect happiness?
Booth: Finding the person that you want to be with all the time, not just sex, it's so much more. Sometimes it isn't even sex at all. (Glances over at her but she's concentrating on her plate.)
They eat in comfortable silence for a few minutes.

Brennan: You know, I did a post-doc with Dr. Harris. I can't believe he's dead, like that.
Booth: Post-doc? I don't know what that means.
Brennan: A research post at university, before I had a professional position in a lab.
Booth: Hmmm. I didn't look at university work, I'm going to have to check on that too later today.
Brennan: Well, you know I can help you with that, I know all of these people.
Booth: That's the problem. You can't be objective.
Brennan: I can so. I am the most objective person I know!
Booth: Oh, now that's convincing. I know you are objective, but we really need to go by the book with this one. Trust me, OK? I have to make a call, I'll be back in a minute.
He gets out of the car and walks some distance away, consults some notes in his pocket and makes a quick phone call. He gets back in the car and they return to the hotel.

Brennan: OK, let's have a quick shower and then we can go do some questioning.
Booth: Don't you ever sleep? Although the shower idea--
Before he can finish a group of people come running up to Brennan, waving copies of her books and begging for signatures. Booth runs off towards the elevator.
Brennan: You did this, didn't you?
Booth: You can't disappoint your fans now, can you, Bones? I'll catch up with you later! Play nice!
He goes upstairs to a room, standing outside for a moment. Eventually, he knocks on the door. Cam opens the door to let him in.

--------------------------
That evening they meet at the hotel bar

Booth: Angel, Wesley and I are going to start looking for the suspects. There are a couple of special parties at clubs near the conference venue. There's a good chance the killer will look for the next victim there.
Brennan: Angela and I can come along and help.
Angel: No, this could get dangerous. You don't know how to handle a vampire
Angela (playfully): I do...
Booth (to Angel): Well, actually Bones can kick your ass. She's got a black belt.
Angel: Really? I'm a third degree, what about you?
Brennan: Only second degree, I've been too busy lately to train. Technically, you could kick my ass.
Angel: There's a great dojo I go to here, open all night--
Booth (sneering) OK, done comparing?
Angel: Anyway, dealing with a vampire is more than just tricky martial arts moves.
Booth: Maybe he's right, Bones.
Brennan: Look, Angela and I don't need to be protected!
Booth and Angel: Yes you do!
Angela: Testosterone spill on aisle four!
Booth: Please just do me a favor, this one time? Stay here and stay safe?
Brennan: Call us if you need help?
Booth: OK, Nick Knight, vampire detective, let's go on a stake out, literally. Wesley, you can sit in the back seat and "watch."

The guys leave in Angel's car

Angela: We're not going to let them have all the fun are we?
Brennan: Damn right, let's go.
Angela: I've got the stakes.
Brennan: We don't have time for dinner, we'll lose them. Hurry up!
Angela shows her the wooden stakes Angel had given her. They get in their car and follow Angel's car at a safe distance.
Brennan: I've hardly seen you since we started working on this case. You've been spending a lot of time with Angel.
Angela: Mmmmm Angel.
Brennan: And?
Angela: Do you want details?
Brennan: No. Yes. No! Well-- Yes!!
Angela; He's the most amazing-- I mean he's had over 200 years of practice. He knows what he's doing. He even did his vamp face for me.
Brennan: How was that?
Angela: It could be fun to play once in a while, but I don't think I'd like to wake up with it every morning or anything.
Brennan: I might be missing out on something here. I think I need to start having meaningless sex.
