Ellie POV: "YOU DID WHAT?!" Callen and I shout simultaneously while sitting in shock. Gibbs walks into the room with a little smirk on his face, and I can see the wheels turning in his head as he thinks of what to say.

"You may not remember, Callen, but you were in a different home for a month when you were 11, although you being you, it only lasted the month before you were back with me. In that time I fostered Ellie while her adoption paperwork was going through. She left with her parents the day before you came back to me. She did know I fostered Abby though. Abby was little but she and El were best friends."

"So I had already met the famous Els, as Abbers called her. Ironic considering she always said we would like each other," Callen laughs. I smirk as I realize that Callen is Kitten, as Abby calls him. I think of ways I can mess with him and finally figure out how.

"Hey, Kitten. Likewise."

He looks at me with this deer in the headlights look, and says, "She didn't… How did you? What? I- I- What- How?"

I chuckle and continue smirking at him for a few seconds, before it turns into this shit-eating grin.

"She did."

G growls low in his throat, and I taunt, "What's the matter, Kitten? Embarrassed?" He glowers at me, and then stalks out the door yelling for Abby. I snicker as I hear him stomping up the stairs to search for her.

Callen POV: I stomp upstairs red as blood, yelling for Abby, who promised she would never tell anyone her nickname for me. She was maybe two when she came to Gibbs' and I was 11. She couldn't pronounce Callen so it came out as Kitten, and it just stuck, although she was the only one who is supposed to know. I guess that plan went to shit… She pops her head out of the ops center looking all innocent. "Don't you give me that look, Abbers! You had no right to tell her that! You said that was between us! Why would you tell her that?!"

"Alright, A.) I called you that when she was at Dad's 'cause, it was the only way I could say your name, and B.) We are best friends, we told each other every thing, but she never told me your name, and I never told her your real name 'cause she was gone by the time you got back. I didn't know until we got here!"

Eric, Sam, Kenz, Deeks, and Nell, all peek their heads out of their respective places and say, "Wait, Dad?", with Sam continueing with, "I thought you didn't know who your dad was?"

I sigh and reply with, "Not my actual dad, although he might as well be, my longest foster dad. Gibbs. I lived in 37 foster homes, but his was the last, and longest starting when I was 11 and going until 17, except for a month when I was 11 when I was with another family. Abby was there too, and she is like a little sister to me."

"Why only until 17?" Kensi asks from her desk.

"I graduated early, and went straight into training for the NSA. Youngest to graduate, aside from Ellie. She skipped two years in her analysis training, where I only skipped one in my field training. We graduated 1 & 2 in our class overall, and 1st in our divisions. We had competed against each other, but never really knew each other." I smirk thinking how I had always had a slight crush on her although she wasn't really the type I had believed I had. Sam, Kensi, Deeks, Abby, Eric, and Nell all looked at me with wide eyes, and it takes me a good 2 minutes to figure out that I had said that last part out loud. I feel myself flush and my eyes get huge, and have to fight the overwhelming urge to run. Fight or flight starts taking over, and I can't control it anymore. My muscles tense, and I feel adrenaline start pumping into my system. I can't figure out how to deal with it, and bolt.
