So I thought this would be funny if it really happened. Only a one shot.
I don't own NCIS
Abby: McGee, I need your help!
Tim: Okay, with what?
Abby: Plan Tiva. After you finish your paper work you're going to come down here. Make sure Tony and Ziva don't follow!
Tim: Abby, don't play matchmaker.
Abby: (sighs) But I want to, Timmy. and I need your help! Gibbs already approved it and that's going to help.
Tim: Fine, but what if Tony finds out I helped and get's mad?
Abby: They'll be thanking us, Timmy!
Tim: Fine.
5 hours later
Gibbs: DiNozzo, David; finish your work then you can leave. McGee; go down to Abby's lab – she needs your help.
Tim: Abby, I'm here.
Abby: About time!
Tim: They have work to finish up there.
An hour later (2200)
Abby: Finally, it's 2200! Okay Timmy, you ready?
Timmy: Turning off the elevators, and go!
Abby: There will be no coming out 'till they kiss!
In the elevator
Tony: Great, just what I need.
Ziva: What? You have a hot date?
Tony: No, I don't.
Ziva: Oh, okay.
Tony: We'll probably be stuck in here for hours.
Ziva: Yeah, lets play a game!
Tony: How about two truths and a lie?
Ziva: How do you play that?
Tony: You tell two truths and one lie, and the other person tries to figure out the lie.
Ziva: Fine, you go first.
Tony: I love long walks on the beach, I'm seeing someone, and I've always wanted a family.
Ziva: Always wanted a family?
Tony: Wrong.
Ziva: What is it, then?
Tony: Seeing someone.
Ziva: Okay, my turn! Killed someone with a paper clip, knows Abby is secretly trying to play match maker, and never went to college.
Tony: The second one?
Ziva: Nope, the first.
Tony: You haven't?
Ziva: No, but I will if you misbehave.
Tony: What's misbehaving to you?
Ziva: Tony, I am tired. I am going to take a nap.
Tony: Okay.
After about 20 minutes of what looked like she was a sleep
Tony: I love you, but you'll never know ...
(Tony kisses her head)
Ziva: Ani Ohevet Otcha ...
Tony: You're awake.
Ziva: Yeah I am.
Tony: We need to talk.
Ziva: Yes, we do.
Tony: Did you mean what you said?
Ziva: Yes.
She whispered and put her head down.
Tony was just able to hear what she says. He puts his finger under her chin, lifts it up and kisses her mouth lightly.
Tony: I love you.
Ziva: Tony, if do this we keep everything we do to ourselves ... and it's not just going to be a one night stand.
Tony: It'll never be just a one night stand, and I would never tell anyone what we do or don't do.
Then she kisses him and the elevator starts moving.
Ziva: I think we owe Abby.
Tony: We could always do what she did to us, but with her and Tim instead.
Ziva It is kind of hard to stop the elevator, seeing as we're not computer geeks.
Tony: But we can lock them in the lab?
The next night
Tim: Have you seen Tony and Ziva? Boss said we could leave.
Abby: In there.
Points to the backroom.
Tim: Okay, thanks. I'll just let them know.
Tony: Now
Ziva presses the button that shuts and locks the door automatically.
Tim: Guys, not funny!
Tony: When you get together we'll let you out, but for now; talkie, talkie! We'll be occupying ourselves.
Abby: Should've seen this coming!
Tim: Well it's not the end of the world. We have this stuff.
Abby: I don't wanna think about computers! It's been a long day.
Tim: So how's cadd been doing?
Abby: Don't McGee! I'm tired and really sick and tired of your jealousy and we're nothing more than friends.
Tim: Abby, I just wouldn't be able to live if you …
Abby: If I what?
With that he just kisses her.
Tim: I love you, Abby. You don't have to feel that way too, but you need to know.
Abby: I do love you too! More than a puppy, and more than friend, or a crush, or a boyfriend. I love you like I thought I couldn't anymore. unless that isn't possible.
And a hug to end it.
