4.

As the time went on, the night drew in nearer and the four friends decided to go home.

Jenny noticed the blue police box before anyone else. "What's that? It wasn't there earlier." she said.

Rani glanced at Luke, who knew what it was, but he didn't say anything.

"Just… a normal blue box, blondie." Clyde said.

Jenny rolled her eyes. "Yes, thank you, I can see that." she said sarcastically, leaning against Luke.

"Anyway, I'd better be going home." Cyde said.

Luke nodded. "See you tomorrow." he grinned.

"Yeah." Clyde grinned back and walked back to his home.

"I'd better be going too." Rani smiled as they turned in to Bannerman Road.

"Night." Luke smiled.

"See you tomorrow." Jenny grinned.

Rani hugged them both before bounding across the road to her home.

Luke smiled at Jenny, pulling her close to him.

She grinned up at him.

He lead her up to the door by the hand and he opened the door.

"Luke?" came Sarah Jane's voice.

"Yeah it's us." Luke said as he shut the door behind him and Jenny.

Sarah Jane poked her head around the living room door. "There you both are." she smiled and beckoned them into the room.

Jenny and Luke both walked in, still holding hands.

Jenny's eyes scanned the room and her eyes fell on the Doctor. The smile on her face faltered and she quickly looked away.

Luke saw this and let go of her hand, provoking a small whimper from her and he hugged her.

Jack and Sarah Jane noticed the reaction, noticed how close the two seemed to have got during their time out, but they didn't say anything.

"Jenny…" the Doctor said quietly, causing Jenny to bury herself further into Luke's embrace.

Luke just stood, his arms as tight around her as they would go, confused, he didn't understand her reaction.

"Luke I think you should take Jenny into the kitchen. Or upstairs." Sarah Jane said.

Luke nodded and struggled to pull Jenny from the room, she could barely move.

"What's that about?" Jack asked as he moved to shut the door once they were both out of the room.

"Why now…" Jenny whimpered.

"Maybe it's not all bad?" Luke suggested as they walked up the stairs.

She shrugged. "I don't know…"

They made it to his room, and he sat her down on the bed, standing in front of her.

"You can have this tonight." he told her gently.

"What about you?"

"We've got a small fold up one somewhere. I'll use that one."

Jenny smiled a little, blinking at the tears that had been building in her eyes.

Luke sat next to her and hugged her.

There was a knock at the door, and Sarah Jane waked in. she took in the sight of her son and Jenny, and she smiled softly.

Jenny slowly looked up.

"Are you alright?" Sarah Jane asked, moving into the room.

"Not really…" Jenny muttered.

"I've told her she can have my bed tonight and I'll get the fold up." Luke said.

Sarah Jane nodded. "Jenny your father… he just wants to speak with you."

She shook her head. "No."

"I've told him if you really wanted to you'd have to have either me or Luke with you. He understands."

"I don't want to talk to him. I don't want to see him… I'm nothing to him…" she said.

Neither of them knew he was standing behind the door listening to them.

"Now I don't think that's true." Sarah Jane said gently, sitting next to Jenny.

"He said it himself. All I am to him is an echo, I'm nothing but a soldier, I'm not like him." Jenny said and turned herself slightly into Luke's embrace again.

Sarah Jane sighed softly. "I don't think he meant it. He usually says things he doesn't mean. don't throw it all away, work at it, or at least try to. Think about it? For me? Please?"

Jenny gave a slight nod.

Sarah Jane hugged her around the shoulders. "You can't lose him. Especially if you're both the only family you have." she said gently, getting up and walking to the door. "I'll come and check on you both in an hour or so." she added.

"Okay mum." Luke smiled a little.

She smiled back and walked out, shutting the door behind her.

"You have some explaining to do. Forgiveness won't happen in a day if she decides to see you." she said, seeing the Doctor.

"I know…" he muttered.

"So go on." she looked at him.

"I can't Sarah."

"Can't or won't." she retorted. "In my son's bedroom there's a broken, lonely girl no older than Luke himself and you've known me for goodness knows how long, and you can't or won't even tell me why you did it? How can you tell HER if you won't tell ME." she said and walked down the stairs to rejoin Jack, Gwen and Owen.

"Are you alright?" Luke asked Jenny.

She shook her head, turning her head in to his neck.

He pulled back slightly, feeling her wet cheeks on his skin, he looked at her and tenderly wiped away the tears from her face. "It'll e alright you know."

She looked up at him.

"I promise." he smiled and softly kissed her on the forehead.

The Doctor remained outside for a few moments listening to the movements and conversation inside the room between Luke and his daughter.

A part of him remembered what it was like, watching his children grow up and fall in love. But they were gone. All of hem, but that didn't mean the feeling, the need to protect was gone. He half wanted to go in there, pull her away from Luke and protect her from the entire universe, and half of him wanted to leave, seeing that she was happy and wouldn't need him there. He knew of the sleeping arrangements, but he knew all too well what teenage boys, human or otherwise, were like.

He hoped, for Luke's sake, that nothing happened to hurt her, and he slowly and reluctantly pulled himself away from the door and down the stairs to Sarah Jane.

"So do you know what you want to do?" Luke asked after a few silent moments, just holding her, the gentle rhythm of her beating hearts against his chest.

"Yeah… yeah I think I have…" Jenny said quietly, looking up at him.

They both leaned in and their lips met gently.

After a few moments, Luke pulled back almost reluctantly and he stood up, earning a questioning glance from Jenny.

"Going to get the fold up." he told her.

"Oh, okay." she smiled just as Gwen knocked on the door and came up with a pair of pyjamas.

"Here you go." Gwen smiled. "Toshiko got us all some spare clothes and Ianto sent them up."

"Okay. Thanks." Jenny smiled again, taking them from her.

Gwen nodded with a smile, looking between then and she walked out of the room, back down the stairs.

"I'll go get it now, and you can change while I'm out the room." Luke said.

Jenny nodded while Luke went out, and started to undress.

Luke made his way up the stairs to the attic and pulled the fold up camp bed from a cupboard, and he carried it back down the stairs to the door of his room, taking his time. He waited outside for a moment before knocking on the door.

"Just a sec!" she called, and after about 20 seconds she said "Come in."

Luke opened the door and walked in with it. He saw her dressed in the pink pyjamas she'd been given, her hair tied up in a pony tail down her back, and he set the bed on the floor, unfolding it next to his own.

An hour later, Sarah Jane walked in,and smiled again, taking in the same sight she'd seen earlier on, though Jenny was curled up and had her eyes closed this time.

Jenny opened her eyes to look up at her, and she slowly pushed herself into a comfortable sitting position.

"Are you alright now?" Sarah Jane asked.

"Yeah… thanks…" Jenny smiled a little.

"Have you thought about what you want to do?" Sarah Jane asked, taking another step into the room.

"Yeah… and I'm gonna do it… But I want yo both there with me, please.." Jenny said quietly.

"That's fine." Sarah Jane said softly. "Right you two, sleep, now. Preferably separate."

That remark earned a giggle from both teens.

"We will." Luke said grinning.

Sarah Jane looked at him.

"I promise!" he laughed.

Sarah Jane laughed with him. "Alright. See you both in the morning." she said, giving him a kiss on the forehead before walking out.

Luke turned to Jenny and hugged her before slipping down on to the makeshift bed.

Jenny got under the covers of Luke's bed and turned the lamp off, then she let her hand drop into his waiting one as she laid down, but she couldn't sleep.

She couldn't help but think she'd made the biggest mistake of her life saying she'd speak with the Doctor, and she slowly fell into a restless sleep.
