River looks at the Doctor's pale face and goes to him. "She needs you right now, Doctor. You are the only person in this room that she knows and she needs you. Mum and I will be right outside if you need anything. We don't want to overwhelm Rose."

The Doctor swallows, then nods. "Alright, River, but stay close."

"We will, Sweetie." She squeezes his hand.

River and Amy go outside to wait. They hear Rose cry out for her Doctor, and hear their Doctor murmuring comforting words to her.

In the room, the Doctor is holding Rose's hand during the contractions and brushing her hair out of her face. He's encouraging her to stay strong and talking about the old days when they travelled together.

"Doctor, I need your help down here" Rory tells him. "I think she needs a little help, but I need to go get more supplies from the infirmary. Amy and River won't know what I need."

The Doctor pales again. "Alright Rory, but send your wife and daughter in please. They can hold her hands."

Rory nods and leaves the room. River and Amy come in and sit on either side of Rose and hold a hand. Rose lets out a cry and the baby's head moves down into position.

"You're doing wonderful, Rose. I can see his hair. Nice dark hair."

"Doctor, it hurts so much! I can't. I can't do this!"

River leans down to talk to Rose, "You can do this, Rose. I know you can. I've heard about you. How brave and strong you are. You can do this, now push!"

A bright golden light surrounds Rose, and Rory comes running back into the room just as Rose gives a big push. The baby comes out, right into the Doctor's arms. Loud shrieks fill the air as he starts to cry. Rose falls back and starts to cry happily. River and Amy smile at the baby and the Doctor's eyes fill with tears. Rory holds the baby, while the Doctor cuts his cord, kisses his forehead and hands him to Rose.

"He's so beautiful" Rose sobs happily. "You look just like your daddy, you do. Oh, I love you, sweetheart."

Rose beams at the Doctor and he smiles back. "You were fantastic, Rose."

Rose looks at River, "Would you like to hold him?" River smiles at her and takes the baby.

"Well aren't you handsome. A handsome little Time Lord. That's what you are." River stops and looks at the Doctor. "Oh, he's a Time Lord, aren't there rules when it comes to the birth of a Time Lord?"

Rose looks at the Doctor in confusion. "What rules?"

"When the child is born, the father gives the child their name. A name is a form of protection. I wouldn't feel right doing this in the place of your Doctor, Rose, but it's necessary. Do you know what name he decided on?"

"Your mother's father. Just like you suggested," Rose whispered.

The Doctor holds the baby into the light and murmurs in Gallifreyan. The gold light that was surrounding them, pulls into the baby. The Doctor smiles at Rose, and hands her her son. "He has been named. When he's older, he'll pick his own title. Just as I'm 'The Doctor'. His title will be a promise."

River smiles at Rose, "What will you call him?"

"He is David James Smith" Rose answers. She snuggles the baby to her chest and, "I wish your daddy could see you now, David. He's needed you for a very long time." The Doctor looks up with a sad half-smile. Rose yawns. They can all tell she's exhausted.

"Rose, you need your rest. I can look after David for a while, if you like. Clean him up a bit. I can bring him back when he's hungry."

Rose can sense that the Doctor needs to feel close to David, even though he isn't his real father. Genetically he is in a way. Rose can't dispute that nor would she want to.

"Alright, Doctor." She kisses David's little head and hands him to the Doctor. River stays behind with Rose.

"I know you're sore right now, but if you'd like to shower and change, I can help you. You feel better and Amy can change the bedding."

"I'd like that, River. Thank you." Rose whispers.

River and Amy get Rose cleaned up and settled. Rory gives her a little medication for the pain and they leave her to rest. The go out to the console and find the Doctor talking to David.

"Really, they did that? That's brilliant, David" the Doctor was saying.

"What's he saying?" River asked him

"Oh, he's telling me about how he heard Mummy and Daddy talking about their little Tardis. He has a remarkable memory." The Doctor grinned at River. "Oh, River, take David. I need to let the other Doctor know what's happened."

River reached for the baby and cuddled him close, walking to the kitchen to see Amy. The Doctor pulled out his screwdriver and sent another message to the other Doctor, hoping he would get it. He still hadn't received a reply to his last message and he was getting worried.

In the other dimension, Jake is looking around confused. It's early morning and he doesn't see the Doctor anywhere. He radios into Torchwood and tells Pete. Pete heads to Rose's office, to see if the Doctor somehow returned there, but he's not there and neither is Rose. He can see the messages from the other Doctor on Rose's computer.

Doctor, this is the other Doctor. Rose just appeared in the Tardis. What happened and where are you?

Rose is in labor. Please answer.

Doctor, your son is here.. David James Smith born at 9:48 a.m. on January the 8th. I felt it was necessary, so I gave him his name in the Old Way. Rose and David are both well. Doctor, I don't know what to do or how to help. Please respond.

Pete gasped in shock. He grabbed his phone and called Jackie. "Jackie, is the Doctor there?"

"No, why would he be?"

"He went missing late last night and somehow Rose appeared on the Tardis with the other Doctor. She just had her baby not even 30 minutes ago!"

"What?!"

"She's back in the other dimension somehow, Jacks. I don't know how and none of us know where the Doctor is!"

"I'll get Tony dressed and we'll be right there" Jackie tells him and ends the call.
