It was over a month before she tried anything. He awoke one morning as she was tying his hands to the headboard.

"What are you doing?" He chuckled at her.

"Tying you up." She replied.

He rolled his eyes at her. "I can see this and certainly feel it. But why?"

She smiled and stuck her tongue between her teeth at him. He easily slipped his wrist out through her hastily tied knots. She was trying to be gentle and had left way too much slack in the rope. He sat up and pulled her close to him running his hand down her back. She moaned into him. He moved his hands up to her hair and stroked it as he laid her back on the bed.

Leaving their clothes on he laid down on top of her and slowly put his mouth to hers. She returned the kiss hungrily before he released it and moved his mouth down to taste her neck. He lifted his head and she was staring at him. Her breathing was shaky.

"Are you okay," He asked softly, as he brushed back her hair again and she just nodded. "Are you sure, Rose?"

"Yes."

"Do you want to go further?"

"Not right now." she admitted and he leaned forward and kissed her again.

-DW-

"So when are you two going to get married and give me grandchildren." Jackie asked them the next morning cheekily.

He choked on his tea and Rose thumped him on the back. "Mum," She scolded her, "We are just getting to know each other again, we aren't thinking about marriage, let alone children."

"But maybe we should." He spoke up, his voice barely above a whisper.

"There is plenty of time for that later," Her attention was turned to him now.

"Because we need to, do you want children Rose?"

"One day in the future." She stated.

He nodded without saying anything and took another sip of his tea. "What about you Doctor," She asked him.

"I've been a father before," He admitted.

"What?"

"It was a long time ago."

"What about now, do you want kids again?"

"We should really discuss this later," He suddenly agreed with her and then looked towards, Jackie who was pretending to be more interested in the newspaper.

"Why, can't you just tell me, Yes or no?"

"Rose, please not right now?"

"Don't do this to me Doctor," She said firmly. "You started the conversation now answer me, do you want to have kids with me."

"No"

"Why not?" This time she sounded sad and it broke his hearts.

"Because we can't have kids Rose," He stated sadly stroking her cheek. "It is biologically almost impossible. If on the low chance you do conceive it is even less likely you will be able to bring the baby to term. If somehow you do, and they are Time Lords, even part Time Lord, they could have all sorts of problems including making too much energy and burning out, or not making the energy that they need. Both of which can and will kill them."

"How low is the chance I could get pregnant?"

"About 5% and it is only an 3% chance that if you do that you can carry the baby to term, or at least long enough to give birth safely."

"Why didn't you tell me before?" She sounded angry now.

"I wanted to see if there was actually a chance we could make it work before I brought it up." He went to touch her and she flinched away from him before standing up to leave the room.

"We are not starting this again." He said angrily as he grabbed her wrist. She swung around quickly and with her free hand slapped him hard across the face.

"Let me go," she hissed.

"No." He said firmly. She brought her hand around to hit him again and he grabbed that wrist as well and was now holding them both firmly. "Talk to me."

"You're hurting me." She cried out.

"Only because you won't relax. If you would just relax it wouldn't hurt. Now Rose just talk to me." He pleaded.

"Doctor if you ever loved me, then you will let me go." She cried.

"It is because I love you, that I can't."

"Doctor," Jackie said warily, speaking up for the first time since the argument started. "You need to let her go and Rose you need to calm down and talk to him. Whatever is going on between you two is getting wearisome." She stood and left the room as they both watched her. He wondered briefly when Jackie had become the voice of reason.

He looked at his hands still firmly wrapped around Rose's wrist and then to her face and saw the tears streaming down her cheeks and the fear in her eyes. She had stopped trying to pull away from him. He released her wrist feeling ashamed of himself and expected her to run away, so he was more surprised when she sat down next to him. She looked worn out and when he tried to put his hand on her again, this time she let him.

"I'm sorry, I flinched away."

"I'm sorry, I didn't tell you sooner."

"No, you were right. There was no need. We can't even have sex, how can we have children." She took his hand and kissed it. "I don't suppose you would consider adoption." He just shook his head. "I didn't think so. So where do we go from here."

"I don't know," He replied not looking at her.
