Jack followed the Doctor out, looking around. He'd taken him somewhere unfamiliar, but in his experience, most engine rooms seemed to be about the same. He frowned at the Doctor's insistence that he was going to die soon. "We'll talk about that later."

He followed closely behind him, not knowing exactly where they were going, but he could already hear the reactors, and the menacing buzz shot a chill through him. He swallowed and nodded, unfastening his shirt again and climbing out of his bracers and trousers. John would never forgive him if he had to stay away from Jack because of a silly thing like irradiated clothing.

"I know... I'm not stupid. I mean, it's not like we haven't done this before, right?" Jack laughed and winked. It was about all he could do to keep from getting scared. "Just... maybe don't let me die." He smiled and pressed the button on the panel that let him into the room and headed straight in without another word.
