The words snapped him out of his reverie and he went from absolutely destroyed to a picture of perfect stunned shock, gaping at the Doctor and the area around them. "What..." he managed. "Why..."

He wanted to ask what the Doctor was doing there and how he could be there, but there was a fine sort of relief that filtered in, because if the Doctor was here, the chance that he'd gone back home for good wasn't highly likely. "That, right there, what I just did," he said, yanking the phone closer to him and trying to recall Kayla's number from memory (he couldn't) before swearing and searching for her chart. "I just sent that woman out the door to die," he said thickly.
