Martha practically skipped down to the Tardis' sleeping quarters. This would be the first night she'd be sleeping on board. The Doctor was still at the controls, setting the Tardis down where they could hopefully sleep unaccosted. There were doors lining each side of the hallway Martha found herself in. She stopped and looked into the first door on her right. It was a decent size and looked like any bedroom you could find on Earth, except for the branchlike structures connecting the floor and ceiling and the same circular lights that were everywhere in the Tardis. There was an unmade double bed in an intricate metal frame. Right across from the door was an oval mirror mounted on the wall above a dressing table. The table was littered in hair products and accessories. Martha stepped inside unable to curb her exploratory nature. She explored the trinkets that were on various shelves, which seemed to come from a multitude of different times and cultures. If it weren't for the hair accessories and women's clothes, she would have thought it was the Doctor's room.
There was almost a strangled noise from the door behind her. Martha spun and found the Doctor standing in the door frame. Behind his attempt to look impassive, Martha could see a great pain. "Um. Whose room is this? Yours?" She asked.
The Doctor sniffed and rubbed his eye. "No. This room belongs to Rose."
"Oh. Your friend." Martha turned back to look at the room. "She still has a room. Are you expecting her back soon?"
He took her by the arm and led her from the room. "No. She's not coming back. There are many other rooms here you can choose from. Not this one though." He pulled out his sonic screwdriver and pointed it at the door.
Martha stood there staring at his back, hurt, as blue light pulsed around his hands. When he turned back to face her he was his usual falsely chipper self. "So. Yes. Any other room. Well except for that one," he said pointing to the room directly across from Rose's room. "That one is mine. Don't use it much though. Anyways, lots of other rooms. I'm sure one of them will be to your liking." With a flash of a smile he tucked his sonic screwdriver back inside his jacket and strode back towards the Tardis controls.
Martha sighed at his retreating figure before continuing down the hallway to find a bed to sleep in.
Back at the Tardis' controls the Doctor fell into the seats, with his head in his hands. He'd peeked into Rose's room and spent more time in there than he cared to admit. Even to himself. He scrubbed at his face with his hands. Straightening he leaned forward and caressed the Tardis' controls, remembering the times he stood there looking across at Rose beaming at him, waiting to discover what was waiting for them outside the Tardis doors.
A few nights later found the Doctor outside of Rose's room, sonic screwdriver in hand. He smiled sadly to himself as he heard the lock click open. He stepped in, closing the door behind him. He sat on the bed, which was much more comfortable than it looked, and looked around at all the bits and bobs scattered around that proved that once Rose Tyler lived aboard the Tardis with him. She never did get around to tidying it and he couldn't bear to move anything. Her dirty clothes were still in a pile from where she'd changed in a hurry, when he'd found them a new adventure.
He lay down and sniffed the lingering sent of Rose that remained on the bed linens. He closed his eyes remembering all the times he'd come in when she'd be in here resting from saving various worlds. Sleeping off the adrenaline crash. The first time he had just wanted to return her phone that she'd asked him to hold onto while they went exploring since her dress didn't have pockets. She'd collapsed on top of the blankets and fallen asleep. She looked beautiful. He'd quietly left her phone on the dressing table and went back to his room.
It was some weeks later, when Rose had had a cold that she'd asked him to stay with her for the first time. He's come to bring her a cup of tea and she'd asked him to lay down with her. 'Cuddling'. He'd stayed that night and it became a regular occurrence after that. They never spoke of feelings. Never putting a name to their relationship. They simply enjoyed a bit of a break from all the running by holding onto each other. Taking comfort in their closeness.
The Doctor felt the single tear roll down his cheek. He wiped it away and got up. He left the room and resealed it with his sonic screwdriver. He was a Time Lord. Onto another time. Another adventure. Though he knew he'd find himself in her bedroom agan.
