Pete looked around and notices Rose's screwdriver laying by her desk. He knows that that is how Rose and the Doctor had been communicating with the other Doctor, but he's not sure how. He roots through Rose's desk and almost cheers when he finds a small note giving a description of what each screwdriver setting does. He finds the setting for sending 'inter-dimensional timey-wimey texts'. He sits at Rose's desk and types a message for the other Doctor.

Doctor, this is Pete Tyler. I found your messages on Rose's computer and her sonic screwdriver was left behind. We can't find our Doctor, he's gone missing. We're doing everything in our power to locate him, but I'd say that if Rose was sent to your dimension maybe our Doctor has too. Don't tell Rose he's missing unless it's absolutely unavoidable. I don't need her worried. Thank you for the news of our grandson, please take care of Rose and David until we get this straightened out. If you think the Tardis is too dangerous, Mickey is back in your dimension now. I'm sure he'd welcome them both. We hope all is well with you. I hope you get this, I've never sent a message via screwdriver before. – Pete.

All Pete could do now was wait and hope for a response, hope their Doctor showed up and pray the Doctor, Rose and David would be alright.

Back on the Tardis, the Doctor receives the message and sighs. Amy comes walking up to the console and reads it. "Doctor, you can't not tell her. She needs to know."

"Oh Amy, I know she should, but she also might want to go to Mickey's and a small flat in London won't be safe for her and especially won't be safe for David. Do you even understand how many people out there would love to get their hands on a newborn Time Lord? An actual Time Lord? River only shares a few characteristics with a Time Lord and look what they did to her."

"So I'll explain to her what happened to my daughter. I'll tell her that the Tardis is the safest place for them right now."

The Doctor let out a resigned sigh, "Alright, you can explain, but wait awhile and let her rest. We can talk to her later when she wakes up. I'm going to give young David a bath I think. Clean him up nice and proper for his mummy."

Amy smiles as the Doctor heads to the kitchen to get David from River. She can only imagine what it's like for him right now. His old love back on the Tardis and having a child that isn't really his, but isn't really not his. She was very proud of how River was handling it.

Rose woke up a little later when she heard her door open, she saw River glance in. "I'm sorry if I woke you" River whispered, "I just wanted to make sure you were comfortable and to see if you might be hungry."

"I'm a little hungry. I'd like to eat in the kitchen though, do you think that'd be alright?"

"I'm sure it'll be fine" River smiles at her. "Let's get you up and to the kitchen then."

River helped Rose up and they slowly made their way to the kitchen. They were passing a small bathroom when the most beautiful sound was heard. It sounded like singing, but Rose had never heard anything like it. She looked at River and River smiled, "The Doctor is singing a Gallifreyan lullaby. Gallifreyan already sounds like music, so actual music is doubly beautiful. He's giving David a bath." Rose stopped and listened for a while, but her hunger got the better of her, so they continued on to the kitchen.

"The Tardis has changed a lot since I was here last." Rose told Amy as she placed a plate of food in front of her.

"He crash landed in my backyard when I was a child. It was right after he regenerated. The Tardis had to upgrade. He had to save the whole planet without a Tardis or his screwdriver." Amy smiled.

"My Doctor felt the regeneration somehow, so we already figured he looked different. What's with the bow-tie though?"

"He's thinks they look cool…" Amy began,

"No, I KNOW bow-ties are cool. David agrees with me, don't you David?" the Doctor said, walking into the kitchen, "Yes, yes, there's your mummy, but let mummy eat first." He looked at River and laughed. "He's a bit nicer than you were River, you called Amy 'The big milk thing'." River laughed and Amy rolled her eyes. He looked at Rose, "I speak baby." And Rose laughed.

"I'm finished eating, let me see him" Rose told the Doctor. He handed the baby over. David started crying.

"Um, he's hungry. I think we'll leave two of you alone."

"No it's fine, you guys go ahead and eat. I'll go back to my room and feed him." She told them. "Doctor, do you have a small cot I can lay him in after?"

"Yeah, I'll get it for you."

The Doctor and Rose with David leave the room. Rose heads to her room and the Doctor goes into storage. He finds his old cot. The last person to have slept in it was the Flesh Melody. He cleans it up and carries it down to Rose's room. He walks in and freezes. Rose is sitting in a chair, rocking David while he nurses. It's a beautiful moment. Rose looks up and sees the Doctor. He turns his head.

"Sorry, Rose. I'll just leave this here then."

"It's fine Doctor. Come in." she tells him. "That's your old cot, isn't it?"

"Hmm? Oh yes, yes it is."

"My Doctor copied it for David. It's mostly silver but with Tardis blue symbols. He just finished writing David's proper name on it a few days ago."

The Doctor smiles, "I'd like to see that."

"I think you'd like to see the nursery. It looks like the console room of the Tardis…well the old Tardis console room. The one I remember. If I ever get home, I'll send you a picture."

"Speaking of home, I got a message from Pete. I'm not supposed to tell you, but it's important. Your Doctor has disappeared. They can't find him anywhere. Pete seems to think that maybe he was transported to this dimension somehow as well."

"What? When did you find out? How did Dad send you a message?"

"Apparently you have your own screwdriver now?" Rose nods, "Well you left it behind and he figured out how you were sending me messages."

"So what are we going to do? How are we going to find my Doctor?"

"I don't know yet. I'll figure it out, Rose, I promise." He tells her. "I'd better get back to the others, you need your rest."

The Doctor leaves her room and Rose finishes feeding David. She goes over to the cot and realizes that the Doctor left some nappies inside, so she changes David, then lays him down. She leans down and kisses him, then slowly goes back to her own bed and falls asleep quickly.

The Doctor makes his way back to the console, River is there flying the Tardis. Amy and Rory are sitting down talking. "Where are we going, River?" the Doctor asks her.

"I don't know about you, but I want to go baby shopping." She says with a smile.

"River…any excuse to go shopping." He laughs.

River lands the Tardis in London. She looks at the Doctor, "You need to stay here and protect Rose and the baby, and she'll probably sleep for a while now, so you are on baby duty." She laughs.

He nods, "Alright River, but be quick will you."

River, Amy and Rory leave the Tardis. "River, where are we?" Amy asks her.

"Near the Powell Estate" she answers.

"Why are we here?"

"This is where Rose lived, I landed us here, a year before you met the Doctor."

"What? Why?"

"The Doctor used to come here sometimes after he lost Rose, I'm hoping that if her Doctor is in this dimension, we might find him."

They go around a corner and see another Tardis sitting there.

"Oh no."

"What?"

"Rose's Doctor is here alright, but it's not her human one."

"What are we going to do?"

"Hope the Tardis can sustain a paradox. Two Time Lord minds are better than one. Maybe he can help us find the other Doctor and get Rose home. You and Dad go get baby gear while I find him. I just hope he's met me at some point."
