Kept

Chase became a bigger and bigger part of her life, seemingly for no other reason than he tried. House found himself on a bell curve of amusement and irritation when considering their blossoming relationship, tempered more and more with indifference. By the time they married, he was worlds away, and he doubted very much she would even have spared a thought for him on her wedding day.

Cameron was not so simple as to be held by Chase though. He wasn't the only one to know it, surely, but he was the only one who could freely admit it to themselves. When she had doubts, when she couldn't let go of her past, when she was unable to make herself into the undamaged person Chase thought she could heal to be, nobody was surprised, but House knew it all along: Allison Cameron couldn't be kept, certainly not by some handsome nice guy who compared who she was to how regular people could be, not by anyone.
