"Who isn't?" Nitro replied to Robin with a smile, but her eyes did not leave the Doctor. Something in her eyes seemed to stir uncomfortably, as if she were trying to remember something important, something that related to the strange man who stood before her. "So if you're detectives...what are you doing here?"<br/><br/>"Robin's going undercover. It's all part of a plan to rumble whoever is behind the great cafeteria food conspiracy," the Doctor replied as he swiped one of the pizza slices and sniffed it before shoving it into his mouth. "Its all hush hush, so watch who you tell. Otherwise they could be hamburgers by the morning," the Doctor said with difficulty as he chewed the savory treat.<br/><br/>"You just made all that up," Nitro said, a touch of curiosity lighting up her smile.<br/><br/>"Of course I made it up. I was hungry and thinking about food," the Doctor said after swallowing a mouthful of pizza and wiping his hands on his trousers. "Or maybe I just told you the truth and this is actually a lie to cover my tracks. Dwell on that until the next time I see you."<br/><br/>"Robin, it's time for me to go," the Doctor said before motioning to the doorway. "How about we go and get the last of your stuff out of the TAR...Tar...Car...the car!" The Doctor said after bumbling over a few words, lifting his hat to Nitro in a farewell gesture before he walked out of the room.
