"I'm trying not to." The Doctor let out a sigh, coming to a decision. Even if she did slap him - and he had to admit to himself, he more than deserved it after running away from her like that - it was better to be slapped than to avoid her. Though when she ended up leaving, or he did, he was going to have a hard time letting her go.
"Should go find Rose, apologize for running away." Not something he was accustomed to doing. Not something he'd really done all that often, for all the guilt he carried.
