Rose smiles as the Doctor left knowing g that's how they were now too. Love birds. She could get used to being by his side having given him freely everything that she was again. 
Caitlyn steals the broken kiss that the Doctor interrupted and stands a mournful sigh escaping her but she wore a smile to belay her action letting him know that she understood but was disappointed. "Alright. But before we leave I'm going to grab a few things from the wardrobe. Shouldn't take me more than five minutes to get everything I might need." She said determined to be prepared for anything. Even having to go out on her own.
