Jackie and Pete (Parallel Universe) have another daughter named Sadie, who Rose cares for deeply.

Rose's POV:

The Doctor didn't have time to reply before Rose's mobile went off. She answered with Jack and the Doctor looking on expectantly.

"Hello?"

"Mum?" Rose asked, "Why'd you phone me at work?"

"Sorry sweetie, but I was wondering if I could drop Sadie off there, she had another nightmare and only wants you." Jackie's answer sounded slightly pleading.

"I guess you could, I don't think that will be a problem."

"Sadie?" The Doctor asked to no one in particular.

"Hush!" Rose piped.

"Who was that?" My mum piped.

"The Doctor!" Rose was unable to keep away the smile that spread across her face.

"Really! He finally came to Cardiff, what for?" She asked.

"Sadie?" The Doctor asked again.

"Can't talk right now mum, just bring Sadie on over." Rose hung up the phone.

"Sadie?!" The Doctor said, this time directing the question at Rose.

"Calm down Doctor, Sadie is my little sister. Well half-sister, well...I don't know. Parallel dad and real world mum, it's all a bit confusing really." She answered.

"Oh, cool, how old is she?" The Doctor's eyes brimmed with curiosity, the way they did every time the Tardis landed somewhere new.

"Four and she knows all about you. I told her our adventures as bedtime stories." Rose replied.

The Doctor's eyes brightened even more at that little fact. "Really, does she like me?"

"Oh, yes! She thinks you're the best person in the universe...next to me." Rose looked mischeviously at the Doctor at the last part.

"Next to you. Well that can be expected, because you are the best person in the universe, even to me." He said meeting her eyes.

Sorry about the short chapter, but I thought it was cute!
