He and Rose don't get along quite how he thought they would, not at first. There are too many rough edges, too much hurt, too much pain. Sometimes she can't bear to look at him, haunted by who he was and who he could be.

The soldier he was and the soldier he is.

They don't quite know how to work their differences out, only that they have to or else they won't be able to survive together. They'll splinter and shatter and crumble to pieces, no matter what else they've been through together.

He needs to heal - and so does she. Or else they'll never survive together, instead the soldier he had been made into and the girl she had once been. They need each other for that.

They always have done.
