Jackie and Pete had been very hospitable hosts. They'd given River a very large bedroom with an en suite and a private sitting room- very much to her liking. Especially since the DocTwo's rooms were just next door to the right. She had great plans for this arrangement.
The first night in the Tyler mansion, River had approached the DocTwo for some nightclothes and a spare toothbrush. She thanked him as she turned to go out into her room.
"Does he know?"
"Pardon?" she asked innocently as she turned.
"You're more than just another companion. They may not know it, but I do. The Doctor. Your Doctor. Does he know?" His eyes bored into hers, arms crossed as he stared at her intently.
She dropped the façade. "How did you-" Then she held his gaze and smiled slightly. "Yes. He does. Which is why he'll be so anxious to come for me."
"Part of the reason."
"Yes. Part of the reason." She gave into her smile even more as she thought of her family and her ridiculous husband who was probably scouring their universe for her.
"And your Rose Tyler. Does she know about you?"
"Well," he said as he leaned against the door, "I thought she did when I stayed. Thought she felt the same. But now…"
"But now you two are living on opposite sides of a very large manor. I'm guessing that's not a coincidence?" River nudged.
The man in front of her looked into her eyes before slightly shaking his head, and he saw an understanding and a devotion there he wasn't quite ready for. She seemed to be able to read him- all of him, and there were very few people who had ever been able to do that. Not that he was surprised, necessarily, because he knew at least part of what their relationship would become were he still the original Time Lord, but it still unnerved him when someone looked past the walls he had spent years constructing. He had spent most of his life, at least the life he actually existed, not the life inside his head, trying to break down those walls, to let Rose in, but it didn't seem to have any effect on the human girl in love with a completely alien man. A man who had once cared deeply for her. A man who, similar as they were, was not him. Yet here was a woman who knew him- well, a version of him- inside and out, and loved him all the same. That knowledge worked as a salve on his one heart.
River took a tentative step back into his room, still holding his gaze as he moved aside to let her in.
"I bet we have quite a lot to talk about, Sweetie."
A few hours later, River left the DocTwo's room with a smile on her face and a plan in her head. Hello, Rose Tyler, she thought with a smirk firmly planted on her visage, I'm River Song.
