Jack chuckled at The Doctor's words, agreeing completely that Rose was jeopardy-friendly. He continued to smile brightly, shaking his head in a little amused way when the Master danced Rose around. He side stepped out of the way, moving to stand next to the Doctor, placing a hand on his shoulder and giving it a light squeeze. He looked like he wanted to say something but only ended up giving his head a little shake, a breathy laugh escaping his lips. His look said everything: How do we keep getting ourselves into these situations? How many more times will be able to dodge these bullets? How much longer will you be able to put up with us immortals popping up. Exactly what step does the Master seem to think he is dancing too?
With a little sigh and one more pat on the Doctor's shoulder for good measure, Jack went to move away. "I've got some calls to make, why do i see myself getting slapped again in the near future?" He muttered as he once again stepped around the couple, turning to face Rose as he walked backward toward the door. "Rose, i'll send Ianto down with some extra clothes for you. Because as much fun as you are naked, you cannot meet your awaiting public like that." He smirked before leaving the room, and the three to a bit of privacy before the poor woman was bombarded with family and co-workers.
