She didn't follow him.
In his head it had gone differently. He had visioned her walking onto the lift. There was be an awkward moment. She would be cold and professional. He would be cold and well, his usual self. He might make a quip about her still not knowing what he had signed to the patient. She would try to not to look at him in case she smiled. The atmosphere would linger at his home. She would make preparations for him. She would search for his stashes, find the key for the bedroom. She would finally chance a look at him and maybe give him a half smile showing that she hoped it would all work out. He would go to the bedroom, sit on the bed and wait for the hell to start. But she would nurse him. She would listen to his cries. She would be a rock.
He tried to be strong. He went through his rooms methodically, taking out all of his vicodin and putting it in an empty shoe box. Once he found it all he went to the bathroom. He hesitated as he opened the first bottle over the sink. He watched the tablets tap, tap down the ceramic sink and disappear down the drain. Five bottles later he felt empty. He sank down onto the floor and held his hands.
He wasn't sure what would happen to him now.
Cameron paced the office. Her head and heart were at war over what to do. She'd wanted to get on that lift. Oh, how she had wanted to. Her heart longed to help him and a large part of herself simply longed to be close to him. But her head had won. She took a seat at House's desk and began to look through his paperwork to keep her mind occupied. After an hour or so of reading letters and looking through a new case file that Cuddy hoped House would consider Wilson sat down on the seat in front of her. His long brown coat was draped over his lap, and his briefcase sat at his feet.
"Are you going home now?"
"No, I'm not. I have to go away for a few days."
"What now?" Cameron asked with a squeak.
"There's a symposium I have to attend. I'm a guest speaker."
"But... but House needs you."
"House has know about this for weeks."
"So why would he..."
"Cameron, I really don't know why House does these things. I hope it'll all work out for the best for him but I really can't stay to nurse him."
"He can't go through it on his own."
"I'm not going to say if he can or not because I can't help him. If you feel you should then go, but just make sure you're doing it for the right reasons."
"What other reason is there than he needs someone?"
"That doesn't mean that someone should be you. Just think about it."
He gently squeezed her hand before gathering his things together. With his final glance as he left the room he could see her mind was already made up.
