Rose's POV:
Slowly the trio's laughter died, though, every time they looked at one another, the silence would set them off again. The chime of Rose's mobile phone drew finally their attention away from their persisting giggles.
Pulling the small piece of human technology from her jacket pocket, she answered, cutting the chiming off abruptly. "Hello?"
"Hi sweetie, sorry for bothering you at work, I was wondering if I could drop Sadie off there." Jackie's voice came from the other side of the phone, with what sounded like a child crying behind her. "She had another nightmare, and she only wants you, this is what happens when you tell her all those st-"
Rose cut her mother off, she didn't feel like hearing yet another lecture on her bedtime stories, "Mum it's fine if you drop her off, I'll see you soon."
"Sadie?" The Doctor sounded confused as he asked anyone who would answer him about the little girl.
"Hush!" Rose piped before going back to her phone; she didn't have time at the moment to explain who Sadie was. "Mum? Are you going to bring her?"
"Yes, I'll be there as soon as I can." Jackie sounded indignant at being cut off by her daughter but she had too much to worry about with the crying child in the background. "Who was that in the background?"
Rose tried to hide her excitement, but she couldn't help the smile that spread across her face, "The Doctor."
"Really?!" Her mother sounded as shocked as Rose had been, "He finally came to Cardiff, what fo- You know what it can wait." Jackie trailed off for a moment and Rose could hear her soothing voice talking to Sadie. "I'll be there soon, love you."
"Love you too mum, see you soon." With that the blonde girl hung up her phone and placed it back in her pocket, turning back to face Jack and the Doctor.
"Sadie?" The tall alien looked confused, but Rose could almost say there was a darkness of disappointment in his eyes.
"Oh, calm down Doctor, Sadie is my little sister…well half-sister…I don't know. Parallel dad and real world mum, it's all a bit confusing really." As Rose spoke the air of disappointment about the Doctor changed to excitement.
His brown eyes brimmed with curiosity, "How old is she?" He looked as excited as he did whenever they landed on a new planet or discovered some type of unknown alien.
Rose was happy to share in his excitement; actually she was happy to be with him at all. "She's four…and she knows all about you."
The TimeLord looked taken aback, "How so?"
Rose giggled at the Doctor's confusion, "I've told her a few…and by a few I mean many of our adventures as bedtime stories."
As he smiled, Rose couldn't help but smile back, "Really, does she like me?" He asked pompously.
"Oh yes! She thinks you're the best person in the universe," She glanced mischievously at the Doctor as she continued, "Well, next to me."
"Next to you," He repeated meeting her eyes. "Well that can be expected as you are the best person in the universe, even to me."
