The way I was thinking with this is no teenage Dawn just little Dawn who Buffy gave birth to.
Buffy Summers-Rossi hadn't been in the States in six months. She, her daughter Dawn, Giles, Xander, Willow, and some of the mini's had gone to England. Getting the Watcher Council set up and finding all the newly called Slayer's had left Buffy and the Scoobies extraordinarily little time for anything else but that. She would talk to her father at least once a week sometimes more when Dawn wanted to talk to her Nonno. Her father had come to visit her in England for two weeks about three months ago. Buffy and Dawn had enjoyed their time with him. Now she was ready to go home to the States and if everything went as plan Buffy would be setting up shop nearby.
Buffy Summers-Rossi, her daughter, and her daughter's nanny/driver Nico Barone had arrived back in the US early Friday morning. She dropped Dawn and Nico off at her Virginia home not far from her father's place. Buffy took a cab to her father's work so that Nico could bring Dawn to her father's place later or her father could take her home. Using her connections Buffy put her plan into motion. When she arrived outside of the FBI building, she paid the cabbie and then waited for the confirmation text that everything was ready. The text came a few minutes later and she dug out her ID that gave her clearance to get into any Federal building uncontested. Once she was finished with security, Buffy took the elevator up to her father's floor. She exited the elevator to see the bullpen empty of her father's co-workers. With a smile, Buffy went to her father's office and sat down at his desk.
Aaron Hotchner, David Rossi, Derek Morgan, Jennifer Jareau, Spencer Reid, Emily Prentiss, and Penelope Garcia were sitting in the conference room waiting for their section chief Erin Strauss. She had called telling Aaron that she wanted everyone to be at the emergency meeting she was calling. Everyone was beginning to get anxious having been sitting for more ten minutes with no sign of Strauss. They were talking quietly when Rossi's cell rang. He pulled his cell out and look to see who was calling and then looked up at everyone with a puzzled look.
"It's my office number." He hit the button putting it on speaker phone. "Hello?"
"About time I thought I was going have to call back. Can you guess where I am?"
With a huge smile on his face, Rossi got up from the table and hurried from the room. Behind him his co-workers followed wanting to see who the mysterious person was. Rossi reached his office to see his daughter sitting behind his desk grinning madly.
"Buffy!" David Rossi cried out as he entered his office and practically ran toward his daughter.
Buffy got up and met her father part way. The two hugged tightly and Rossi kissed the top of her head.
"When did you get back?"
"This morning." Buffy told him.
"For how long?" Dave asked with a hopeful look.
"Possibly long enough for you to see Dawn grow up." Buffy said with a smile.
"Really?" Buffy nodded yes.
"If we can get the proper funding Giles wants to open several branches around the world starting in the U.S."
"That's great."
"Dave you want to introduce us to your guest and then we have a meeting to get back to?" Unit Chief Aaron Hotchner asked.
"Everyone I want you to meet my daughter Buffy. Buffy, I want you to meet our Unit Chief Aaron Hotchner, Special Agents Derek Morgan, Spencer Reid, Emily Prentiss, our Communication Liaison Jennifer Jareau, and our Technical Analyst Penelope Garcia."
Everyone but Aaron had been shocked that this beautiful short blonde was Rossi's daughter. Aaron knew Rossi had a daughter and a granddaughter as he talked about them often to Aaron but was caught off guard by how attractive she was.
"It's nice to finally meet all of you and put faces to the names, and don't worry about that meeting. It was just a diversion so I could get up here without dad seeing me."
"Are you saying you used our Section Chief as a diversion?" Emily asked a bit shocked at the idea.
"Technically I called her boss and he used her as a diversion but potato…potahto." Buffy said with a shrug.
"Buffy, where are you hiding my granddaughter?" Her father asked.
"She's at home with Nico her Nanny probably getting ready for her nap. If they can spare you for the rest of the day you can take me out to lunch, and she should be up by the time we finish."
"Go on Dave it's been a slow. Go on and spend some time with your daughter and granddaughter." Hotch told Dave.
"Let me get my things Figlia and we can get out of here."
Dave grabbed his things and then put his arm around his daughter and the two said goodbye to the others before walking to the elevator.
The following week had been a tough one for the BAU. The case had been a tough one involving children. Buffy had texted her father and told him to invite the team to her place on Saturday for a gathering if they made it back before then. The team had gotten back Thursday and had agreed to come to her place. On Saturday, her father had come over early to help her prepare. Buffy, her father, Dawn, and Nico all helped in preparing the food. They made spaghetti with homemade meatballs, beef stroganoff, vegetable curry, and vegetable lasagna. They had the oven, stove, and several crock pots going.
Rossi had told everyone that they could come at four, but dinner wouldn't be till five. Buffy had set out the veggie tray and the cheese, meat, and cracker tray for appetizers. At four the guest began arriving. By four-thirty everyone but Aaron Hotchner had arrived. Dawn wanted to show everyone the house and grabbed Spencer's hand pulling him along. The others laughed and followed behind listening as Dawn pointed out rooms. While Dawn was doing that, Buffy was in the kitchen finishing up final preparation when the doorbell rang.
"I got it!" Buffy yelled to her father who was with the others on the tour. Buffy opened the door to see Aaron Hotchner and his son. "Hello Agent Hotchner, glad you could make it."
Buffy said as she moved out of the way to let them enter.
"Sorry, we're late, and please call me Aaron. This is my son Jack. Jack, this is Miss Summers-Rossi. She's Dave's daughter. Can you say hi?"
"Hi." Jack said a bit shyly. "Are you really Uncle Dave's daughter?"
"Yep, and you both can call me Buffy because when anyone calls me Miss Summers-Rossi, I think I'm trouble." At that Jack giggled. "The others should be back soon. My daughter Dawn, she's five, is giving them a tour of the house. Help yourself to some of the appetizers and can I get you something to drink?"
"Can I have some juice?" Jack asked and Buffy looked at Aaron who nodded yes.
"Why don't you come into the kitchen and pick what you want?" Buffy offered taking him to the fridge with the door that Dawn could reach when she wanted a juice. Looking over the juices, he finally selected a fruit punch juice box.
"What do you say Jack?" Aaron prompted.
"Thank you." Jack said with a charming smile.
"You're welcome. You are going to be a heartbreaker when you get older. What can I get for you Aaron?"
"Water will be fine. Did you make all of this?" Aaron asked as he sat Jack in the barstool and then took the seat beside him at the counter in the kitchen.
"Here you go." Buffy handed him a bottle of water. "Well Dad, Dawn, and Nico helped but yeah we made everything. We wanted to have something for everyone, and we have cake and pie for dessert but those are store bought. We're not so good in the baking department unless you like rock cake." Jack scrunched his nose up at that. "Yeah not very good.
The group could be heard returning from the tour and Aaron, Jack, and Buffy looked up to see them entering the kitchen. Spencer was carrying Dawn in one arm and Henry in the other.
"Dawn Marie! Did you give Dr. Reid the pout to get him to carry you?"
"Maybe." Dawn said avoiding looking at her mother.
"She did and once Reid picked her up Henry got jealous and wanted Spencer to carry him as well." Dave told his daughter.
"I'm sorry Dr. Reid." Buffy said as she came over and took her daughter from him. "Her pout is the one of many things she inherited from me. Dawn, I want you to meet Agent Hotchner and his son Jack."
"Hi." Dawn waved at them both before looking at Jack. "Wanna play?"
"Yeah!"
"Down mommy." Buffy sat Dawn on the ground as Aaron helped Jack down. "Come on Henry."
Dawn called as she rounded out of the kitchen Jack following her. Henry wanted Spencer to put him down and then he toddled off after Dawn and Jack. Nico followed behind him.
"Relax a little before dinner. Nico will watch all three of them." Buffy told JJ and Aaron.
Several hours later saw the adults talking in the Living Room. Nico and Emily had taken a liking to each other and were talking with one another. Dave, Derrick, Will, and Spencer were playing pool, while Penelope, Kevin, JJ, Aaron, and Buffy talked. Buffy excused herself to go check on the children who were watching a movie in the blanket fort Buffy and her father had constructed. Aaron had followed her and two shared a look. All three kids were asleep and huddled next to one another. Henry was in the middle with Dawn behind him and Jack in front of him.
"We got to get a picture of this." Buffy said taking out her phone to take a picture.
Aaron nodded in agreement and took his phone out as well. They both snapped a couple of pictures and sent them to the appropriate people before moving to sit on the couch behind the fort.
"They look so cute and innocent. Aaron, you're going to be chasing the girls away when he gets older."
"I suspect you'll be having to do that too as Dawn is definitely going to be as beautiful as you." Aaron said flirting with Buffy a bit.
"Why Aaron Hotchner are you flirting with me?" Buffy asked.
"Yes." Aaron said with such a straight face that it caused Buffy to laugh.
"That's good cause I find you attractive too." Buffy said giving him one her charming smiles.
"Buffy, would you go out with me next Saturday night?"
"I would love too if I can get dad to watch Dawn. I gave Nico the week off for everything he did today. As long as dad can watch Dawn then I would love to go out on a date with you Aaron Hotchner."
Buffy liked Aaron and she hoped her father could watch Dawn because she would love to have her first date with Aaron be kid free. Though this weekend wasn't over yet, Buffy was already looking forward to the next one.
