It was hard for the Doctor not to give mixed signals. In all honesty he had to give them for the sake of his own sanity. He couldn't run around pretending to hate her; that would just be impossible and contrived. On the other hand, he couldn't let her know just how much he fancied her, either. So, back and forth the pendulum would swing; well, at least until she'd make it stop.
She threaded her arm in his and it felt very nearly like old times: Rose in a pink dress hopping off that moped. If he could figure out a way to grab her hand without being completely obvious he'd do that, too. It was hard knowing what he knew and not capitalizing on just this smallest of opportunties to spend time with her. Even if that time was fleeting. Especially when he knew it couldn't and wouldn't last forever.
"Two and a half weeks," He said, looking off ahead of them as they rounded a bend and were back out onto the main thoroughfare, the gas station quite in sight.
"So, how long've you been travelling with that Doctor of yours?"
