Robin leaned in to inspect the tattoo, a grin on her face. Of course she hadn't met any<em>real</em>aliens that looked like the typical human drawing of one, but it was still a great tattoo. It also meant that Nitro would be fine taking Robin along on her first trip to the tattoo parlor... A more secretive edge appeared in her smile as she thought of her plan.<br/><br/>"Doctor," she said in an amused tone, "In your quest to show off in front of<em>my</em>new flatmate, you seem to have forgotten who it was who decided to come here... Anyway, Nitro, yes. We're sort of... Freelance detectives of a sort." She grinned widely at the Doctor. "Does that title fit us? I think so. The Doctor and Robin, freelance detectives." She whirled again to face her flatmate.<br/><br/>"Are you interested in aliens?" Robin asked nonchalantly.
