Hospital
As soon as John had received the message from Elizabeth, he'd ran out of the door without so much as a goodbye to Sherlock, and he was at the hospital in record time. It was a good job that his apartment was so nearby. He didn't like the increase in work that had come lately- not because he didn't want to work, but because he hated to see so many of their own being so badly hurt.
And now Cuddy? One of the medical staff? He couldn't imagine what the hell had happened to her through that door. But it had happened now, and all he could do for her was fix the damage. She'd be all right. She had to be all right.
