After speaking with the other Doctor for a while, Rose decided to check on the missing Doctor. It didn't take any sort of brilliance to guess that he'd be struggling with a good deal of guilt and there's a part of her that's aware that he may not want to see her at all. She's not going to give him that luxury. She steps into the kitchen quietly, arms crossed over her chest as she approaches him. She knows that he knows she's there. He's probably known since the moment she came into the flat itself. She remains quiet until she's standing a foot or so away from him.

"I know you didn't mean to hurt me. You wouldn't ever. Not on purpose."

It seems the best place to start, acknowledging that hurting her hadn't been his intent.
