At first, it didn't seem as though the Doctor had heard her. He shoved his hands back through his hair and ground his teeth together as he stared at his magnificent time machine's magnificent core sitting perfectly still and quiet. He pushed another series of buttons, and the TARDIS groaned as she tried, once again, to take off, but fell silent after a brief effort. The Doctor took a step back and kicked out, trainer-clad foot colliding solidly and violently with a fortunately unimportant part of the console.
"What is wrong with you?" he shouted. "You brought me here. Now why won't you leave? Rose is here! I can't change! Not now! Not today!" He brought his fist down on the console in a final show of temper before his knees gave out, and he was forced to cling to the very console he'd been abusing to stay more or less vertical. Exhausted, he let his weight carry him down to a seat on the floor, and tipped his head back against the console and closed his eyes. "She's stuck. Something's making her sick. She can't take us to the other ship, and I can't tell from here if they have what I need." Walking was out of the question. He was too weak. It didn't even occur to him that, perhaps, he could simply pick up the phone and attempt to interface with the alien ship's communications systems.
