The Doctor paced around the cell anxiously, trying to take his mind off his issue. Rose interrupted, asking "Why don't you go in the corner?". The Doctor blushed. "How did you know?"

"You did the same at Sattelite 5, remember. Plus, there's only so many reasons to pace around a room."

The Doctor did remember. Unfortunately.

"You know why not. Not happening," he said, sitting down and crossing his legs.

"Come on, it's just me. Besides, who knows how long we're going to be locked in here?"

"No way. I'll just wait, it'll be fine," he said determinedly.

"Well, it's not healthy," Rose warned.

"It'll be fine for me. I worked it out in my head, I've got enough time for us to get out, ask to be let go and get back to the TARDIS. 2 hours and 45 minutes exactly. I'm not a Time Lord for nothing. Superior biology, don't worry." The Doctor assured her.

Rose gave him a look of disapproval at "superior biology". The Doctor rolled his eyes.

30 minutes later, a guard opened the door and asked them to wait for the Emperor, the leader of the planet, whom they had upset slightly by landing the TARDIS in the imperial garden.

The Doctor's need had gotten worse, and so he had no choice but do a slight hopping dance on the spot in front of the door. Soon, they were led in, in front of the Emperor.

As soon as he saw the Doctor, Rose noticed the Emperor got a strange gleam in his eye and smiled with the corner of his mouth at seeing him.

He proceeded to explain that they were going to be locked up for only one night as punishment, then let go. He looked at the Doctor, with a face that suggested he expected an annoying answer, and asked:

"Any final requests before you're transported to your holding cell?", he said with a raised eyebrow.

At this point, the Doctor had calculated he had exactly 23 minutes to find a toilet before his body decided for him. Accepting his fate, he raised his hand.

"Yes, I do, actually. If you wouldn't mind, I'd really appreciate it if I could be excused..I need to take care of a private matter, you know.. of a biological nature.." he stammered, moving his feet nervously, and scratching the back of his head. "You know how it is, drinking a lot of water.." At this desperate attempt, The Emperor laughed, and put his hand up and interrupted his babbling.

"Stop right there."

To the Doctor's astonishment, he then proceeded to speak directly to the Doctor, in perfect Gallifreyan.

"Did you really think, after knowing you for so long, I'd forgotten your little speech, Thete?" he said with a smile.

The Doctor's mouth was half open in surprise. The Doctor looked at the Emperor for a moment. His eyes widened in sudden realization.

The Emperor chuckled lightly. He continued, still in Gallifreyan:

"Now, how about we try that again Theta? What do you really need?"

The Doctor blushed, closed his eyes and gulped, in preparation.

"I need the loo." the Doctor admitted.

"Thought you might", said the Emperor, smiling. He said something to the guard, who then walked over to the Doctor.

"The guard will take you where you need to go, then back here after. Understood?", he asked, now back to speaking English.

"Eh yes. Thank you...Professor Borusa." the Doctor said with a smile, before assuring Rose he'd be "right back", and walking down a hallway with a guard, once again scratching the back of his head, awkwardly.

Rose smiled, seeing that the Doctor would be fine. They returned to the surprising news that the prison sentence was a joke, to remind the Doctor to respect royalty, to which the Doctor sighed, and looked at the ground in slight shame. They were then offered to spend a few days at the palace, which they both accepted.
