I know. I know I haven't updated and I'm so so sorry for it. At some point I just forgot about this story. But now I'm writing again and I really hope the next update will come much faster. The school will end tomorrow and then I'll have plenty of time to write.

In the evening

It was already dark behind the windows of NCIS Headquarters, but in a certain bullpen the lights were still on. McGee had gone home already, Gibbs was somewhere in the building and Tony and Ziva were gathering their things.

Actually Tony had a pretty good idea of where Gibbs might've been, but he was smart enough to not voice it out loud. He had started wondering a long time ago. Wondering why Gibbs always disappeared mysteriously in the evenings and why Jenny always left so late. He had his own theory about where they might be and what they might do, but he was far too smart to not tell anyone. Gibbs would smack him silly if he'd heard his thoughts.

They took their things and headed for the elevator, but went much lower with it than usually. The doors opened with a ding to the familiar corridor which led to Abby's lab. They both could hear excited squealing, which drifted to the couple through the open door. They smiled as they recognized their daughter's voice.

They stepped in and smiled fondly at the sight. Rachel was sitting on Abby's processing table and beside her stood Abby herself. The goth was currently adding something blue to something red, and then, ignoring completely the laws of mixing colors, the substance started bubbling and turned green.

Rachel laughed and clapped her hands with excitement. Abby grinned widely and turned to look at Tony and Ziva. They were grinning too.

"Cool, huh?" Abby asked them, causing Rachel, who hadn't noticed her parents coming, turn around. She smiled widely at them, showing her little white teeth. Tony picked her up from the table, placing a soft kiss on top of her head.

Tony and Ziva nodded. "Thank you for looking after her," Ziva said.

Abby's grin widened even more, if that was even possible. "It was such fun," she exclaimed. "Do you know that she knows the entire periodic table by heart?"

Tony and Ziva exchanged horrified glances, then looked down at Rachel. Abby laughed.

"Just joking," she assured the startled parents, "but think of how cool it would be. She would be ahead of everyone in school."

They all laughed a little. Rach was playing with the collar of Tony's shirt.

"When she is a little older, Abby," Ziva suggested.

"At least we know where to bring her when she'll have trouble with her chemistry classes," Tony added.

Abby's eyes widened like Tony had just offended her. "That," she told him, "will not be necessary. I will teach her chemistry before the class, so that she can be the smartest one in class."

Tony laughed. "Abby, she's four. She doesn't need to know chemistry."

"Well, not yet," Abby said with a wicked smile, turning her eyes back to Rachel, who was content in Tony's arms. "Would you like to see more experiments?" she asked her.

Rachel clapped her hands again with excitement, squealing enthusiastically. Abby chuckled. "See?" she turned to Tony and Ziva, a triumphant smirk on her face. "She likes it."

"Tomorrow, Abby," Ziva assured her. "It is late, Rachel needs to sleep."

Abby's smile dropped just a little. "Okay," she agreed, kissing Rachel goodbye. "Good night, Rach."

"Good night, auntie Abby," the girl replied cutely, reaching out to play with Abby's hair. She laughed and gently saved her hair from Rachel's small hands.

Tony and Ziva turned to leave, but Abby stopped them. "Wait," she exclaimed. "I'll come with you." She ran to the back of her lab as fast as humanly possible on such high platforms. Five seconds later she was back with her jacket and bag.

They all went to the elevator. Abby pressed the correct button and the metal doors shut smoothly. They rode upwards and soon the doors opened again. They exited the building and headed towards the parking lot. They parted with goodbyes and went to their cars. Abby climbed into her car and Tony, Ziva and Rachel into Ziva's Mini.

Please review. Also, tell me where do you think that story will go. I have the basic idea, but any additional ideas are always welcome.
