It was a normal day at the NCIS Headquarters. Tony and Ziva were bickering over the littlest things, like whose apartment they were going to spend the night at, or why Ziva's panties were in Tony's desk drawer. McGee was in Abby's lab. Gibbs was somewhere drinking coffee. Ducky was talking to a corpse.

Actually, both Tony and Ziva wanted to spend the night at Ziva's, but Tony was bored. Bickering with Ziva was something to do, so he said he wanted to spend the night at his place.

Neither of them knew exactly why her panties were in his drawer. Ziva said Tony stole them and brought them in. Tony said Ziva snuck them in there.

That's what they were talking about when Abby and McGee entered the bullpen.

"I did not put my panties in your desk, Tony," Ziva said.

"I didn't take them. And if I did put them in here, it would be the red ones, not these," Tony said, holding them up.

They heard chuckling and McGee said, "Those are yours?" They hadn't noticed McGee or Abby before that.

Tony quickly shoved the panties in his drawer. "Go away McPeeker. You too, Abby."

"McPeeker? You held it up in plain sight," McGee said, sitting at his desk.

"McJealous," Tony mumbled.

"He is not jealous," Abby said, leaning over McGee's shoulder to stare at the computer screen.

Tony sent Ziva a questioning look but she just shrugged in response.

"Aww, he's so cute," Abby cooed

"You want that one?" McGee asked and Abby nodded.

This time, Ziva sent the questioning look and Tony shrugged.

After a minute of doing nothing, Tony decided he was still bored. He found a piece of paper, crumpled it into a ball, and threw it at Ziva. She was looking at her computer screen so she didn't notice until it hit her head. She glared at him but went back to looking at her screen. Tony threw another at her, again hitting her head.

"Do you want me to do the Bobbitt tonight?" Ziva said.

Tony grimaced and shook his head. Out of the corner of her eye, Ziva could see McGee grimace, too.

The elevator door dinged. Assuming it was Gibbs, they all pretended they were busy.

As the person got closer, they heard the clicking of heels. It couldn't be Gibbs.

The clicking stopped. Ziva was the first to look up. Well, it was a woman. A beautiful brunette.

Then Tony looked up. Ziva could clearly see the confusion on his face. When McGee and Abby looked up, they had looks identical to Tony's.

The woman turned to Ziva. "I'm Caitlin Todd."
