Rose rolled her eyes with a fond smile. She knew that, she just enjoyed poking fun at the Doctor from time to time when she could. She hadn't had that much opportunity to do so when she was around him last and had enjoyed the quips between them two. "I wonder does he just randomly go from place to place and just happens to run into his companions, or was it a random jump in hoping to come across the one he's supposed to bring along? That would be an interesting factor about him." Caitlyn asked curiously for it did seem to happen that it was just a random coincidence, as she smirks at him in a challenging way, reacting full heartedly to his kiss not at all caring that they were in public or about anything else. She might as well enjoy the attentions of a flirt while she has them, finding it a bit of fun to see who would get too involved first. Someone wary to the game, or one too used to it? This might actually be fun.
