"No problem at all," Nitro answered with a nod and a grin. She turned on the spot before lifting up her shirt (completely ignoring the Doctor's splutter of surprise) to reveal a tattoo of a little green martian, with a big head and tiny black eyes, riding the legendary bike towards her shoulder blade. She seemed perfectly at ease with showing off her back, even when in the presence of a man, but whether it was because she didn't mind or didn't care was unknown. "Little tattoo I got when I visited Roswell. To tell the truth I got it in Mexico, but it wasn't long after my trip to Roswell."<br/><br/>"Ah Roswell, good times," the Doctor said wistfully, staring into the distance with a small smile on his roughly shaven face. "That was quite a fender-bender."<br/><br/>"Um, right," Nitro said slowly, finally seeming to register the Doctor's strangeness for the first time as she noted the reminiscent look on his face. Her gaze shifted between him and Robin for a moment before she asked. "So...when you say work associates, what do you mean? Are you two part of a business or something?"<br/><br/>"You could call it that. I do make a lot of things my business," the Doctor said with a nod of consideration.
