Daddy's Girls (in this one you are The Doctor and Roses daughter)

You would think sense Torchwood fought aliens and monsters it was some big scary serious place, right? Well your wrong. Captain Jack Harkness like to make sure working at Torchwood was like working with family. To him it was. He had his wife and daughter living with him. And everyone knows when you have a 3 year old daughter everything is a game. What wasn't a game when you were finally able to walk and talking somewhat normally? Jack Harkness loves life. His beautiful wife, (Y/N), and daughter Blair made him a happy man. Well when his women were happy he was happy. But here's the thing. Now I'm not saying Jack was a bad father. He's great. He just has troubles like any first time father would. (Y/N) told him a number times he was doing fine. Even comparing him to her father, The Doctor, who once left her alone on the Tardis at 6 months old. Her mother Rose was not very happy. So this whole first time dad 'jitters', let's call them, hit hard when (Y/N) said she had to leave for a week to help her parents. On another planet. She explained a millions times to Jack that he would be fine that he had all of Torchwood to help. Owen, Gwen, Ianto, and Tosh. So Jack agreed. (Y/N) kissed him goodbye and hugged their daughter promising to be back in a week and to call if possible. And she was gone. Leaving Jack with a crying three year old.
"Momma come back now?" Blair asks in her cute little voice. "Not yet baby. She'll come back soon. She's with Grandma and Papa." Jack reminded her while picking her up and taking her to his office to try to calm her down. "Don't cry sweetheart. Daddy's here. And Momma will be back soon." That just led to more crying.
He picked her up again and carried her around. He still had a job to do even if he had a wailing three year old in his arms. "Jack give her to me." an accent voice belonging to the one and only Gwen ordered. Jack complied and hand over his beloved daughter.
"Now Blair listen up. Your mummy had to go and do some important work, ya?" Blair look at her with teary eyes and nodded, "But she's coming back and you know it. So for know how about you stop crying because pretty little girls don't cry and spend this time with your daddy. I'm sure he would love to teach you all about Torchwood and if he doesn't come ask me and Tosh and I will take you to all the secret hiding places. Got it?" Blair giggled and nodded while wiggling her way out of Gwen's arms. Blair ran to Jack "Will you teach me Daddy?" she asked him in a voice no one could say no to. "Of course baby. Come on."
Jack smiled and held out his hand. Blair placed her tiny hand in his large one and they walked on to explore the wonderful world that is Torchwood.
One week later (Y/N) returned to find the institute oddly quite. It was never this quite. Suddenly she heard footsteps and voices. "You'll never get away Cyberman!" (Y/N) heard her daughter yell. She turned to the left and saw Ianto with tin foil wrapped around him running from the tiny 3 year who was yielding a toy weapon. "Hit him now and he's done for sure sweetheart!" Jacks voice rang. "Bang! Bang! I got you!" Blair shrieked happily. "And the final round goes to the three year old you sorry excuse for Torchwood agents." Jack shouted. "You told us if we didn't let her win we got sent back in time. Hi (Y/N)." Owen said as he walked by pulling tin foil from his clothes. "Momma!" Blair yelled, "Did you see me? Daddy taught me that." "He did now did he?" (Y/N) laughed and looked at Jack who nodded with a small before he kissed his wife. "I did. Now she can protect us. I shall retire early!" Jack boasted. "Probably not." (Y/N) smiled. "And why would that be?" Jack asked as the other agents walked away and Blair ran somewhere. "I'm pregnant." (Y/N) told him. Jack fainted.
