Note: I got a request from Bohogal1998 about Abby contacting Gibbs after she moves to London. So here it is. I hope you like it. This story is set right after s17e11. I hope I have captured the characters well enough. I always try to be as close to the show as possible. Please leave a comment on your thoughts and enjoy it.

Gibbs's phone rings, and he smiles by the look of the caller id. He doesn't get to say anything before he hears the all so family voice calling through the phone

" Gibbs… Gibbs… Gibbs… Gibbs."

" Abby… slow down." Gibbs says a bit irritated but, at the same time, delighted to hear her voice on the phone. "Merry Christmas Abs… How are ya?" he can hear the sound of "jingle bell rock" playing in the background, and he can tell without even seeing her that Abby is walking around with her red Christmas skeleton sweater and her Santa hat on.
"no time for chit chat, Gibbs." Abby sounds very determined. Like she used to do when he entered her lab doing a big case.
"okay… what is the rush?"

"I am asking the questions, Gibbs," Abby says determinedly.

"okay. Am I being interrogated?" Gibbs asks with a smile.

"no. yes… I don't know. Maybe I can pull off a Gibbs-interrogation. I need a cup of coffee." Abby says and then changes her voice to imitate Gibbs. "I need to practice my Gibbs-stare."

"Abby. I thought you said no, Chit chat?" he asks, interrupting her rambling to herself.

"Right, yes. Gibbs. Important question." She says in her normal voice again and sounds very determined, turning her focus back to the reason for her phone call. "I just spoke with McGee. he said…" she holds a dramatic pause. "ZIVA IS ALIVE?" Abby almost yells in the phone, and Gibbs must hold the phone out from his ear to not hurt his ear.

"yes, Abby Ziva is alive. She is okay. She is safe."
"how long have you known?" Abby asks, excited.

"for about 6 months."
"Why didn't anyone tell me? Why didn't you tell me, Gibbs?" Abby sounds disappointed and hurt.

"Abby, Ziva came back because there was a terrorist after her. She had to go underground years ago, which is why she faked her own death and had to hand over Tali to DiNozzo. It was to protect DiNozzo and Tali."
"oh my gosh… poor baby. How is she now? Is Ziva okay?"

"yes, she is fine. She is on her way to Paris now."

"Ohh, she is going to spend Christmas with her family. Tiva is going to be together this Christmas." Abby says, almost dreamy and cheerful.

"what is Tiva?" Gibbs asks, confused.

"not what, Gibbs. Who." Abby says determinedly. "You know Tony and Ziva put together equals Tiva," Abby explains cheerfully.

"Okay." Gibbs just simply says still not following.

"so Gibbs, I spoke with McGee, and he said you got a new little friend named Phineas."
"yes. Phineas was my neighbor across the street. He moved to Philadelphia tonight with his foster parents."

"tell me all about him."
"Not much to tell Abbs. He was 9. Great kid. We spend some time together. That was all."

"you said he moved away?" Abby asks with sadness in her voice.

"yeah…" Gibbs says it hurts him thinking about losing his friendship with Phineas. He had really come to care about that kid. "I'm sending you a hug through my mind, Gibbs," Abby says, and it makes Gibbs smile sadly. Abby has always managed to cheer him up in her own very Abby-way, but the sad thought of Phineas moving away is still pulling him down a bit. It had hit him harder then he thought when he said goodbye to the kid tonight. Gibbs pulls himself out of the though of Phineas to focus on his call from Abby. Hearing Abby's voice always makes him feel better. He decides to tell Abby the truth about Phineas and Sahar.

"his mother was the terrorist that was chasing Ziva. She moved in across the street with her son. She used her son to spy on me."
"oh my gosh. Why do people do things like that?" Abby asks, upset.

"she was a terrorist Abbs. She was working with Ari…"
"Ari as in Ziva's half-brother that Ziva killed 15 years ago?" Abby interrupts Gibbs and gets very upset by the mention of Ari Haswari.

"yes."
"Okay, that man is seriously like a bad case mole. He just keeps coming back no matter what. He died 15 years ago. Why can't he just stay dead?" Abby sounds infuriated by the thought of Ari Haswari.

"he is dead, Abbs. He is very dead. It is just his friends that keep coming back to haunt us."
"how many friends can a terrorist Mossad traitor have?"

"many apparently. But Abbs… what matters now is that Ziva is safe. Sahar is dead, and Ziva is on her way to be reunited with her family, and Phineas is no longer living with a terrorist. He is going to stay with his foster parents that are really great people."
"oh Gibbs, I knew I would be cheered up by calling you." she sounds so cheerful and happy again, and Gibbs can even feel the joy floating through the phone, and it makes him smile too. "you always create Christmas miracles, Gibbs. You are like Santa Claus. You make people happy." It makes Gibbs smile.
"I'm just doing my job, Abbs," Gibbs says, rationalizing her cheerful image of him. Somehow Abby has always had this almost childish image of him as a person who could always save the day, and no matter how many times, he has felt like he has let her down or failed her over the years har faith in him has never fainted away.

"How is London, Abbs?"

"it is great. My brothers Luca and Kyle are here visiting for the holidays, Gibbs. I wish you could be here too."
"yeah, I wish Abbs. I am going to have to come and visit you another time."

"you have to Gibbs. I want to show you everything around here. It is so great."
"you know I have been to London before, Abbs."
"I am going to show you London the Abby-way." It makes Gibbs chuckle.

"okay. I can't wait for that, Abbs."

"I got to go, Gibbs, my cookies are getting burned."
"Okay, take care, Abbs, and merry Christmas."
"Merry Christmas, Gibbs," Abby says, "or merry Gibbsmas," Abby says, sounds wonderous, and it makes Gibbs smile. "Merry Christmas Abbs," Gibbs says with a smile and hangs up. He drops down on his couch and drops the phone on the coffee table. Gibbs lay down on the couch and look up at the decorated Christmas tree in the corner of the living room. He is a smile on his face. A call from Abby always makes Gibbs smile. Considering everything that has happened over the past few months since Ziva showed up in his basement. The emotional rollercoaster Gibbs has been on with Phineas and Ziva and Jack. It just felt nice to receive a call from Abby.
