They reached the cilo and went inside. They started walking down the smelly cramped corridor. An old man appeared in Luna's view.
He looked between Jack and the doctor. He went back to Jack. "Doctor?"
"That's me" the doctor said, "actually it depends what you want."
"How so?" He asked.
" I am scientific doctor she's in medical." He explained quickly.
We followed the man to a lab luna and Martha left the men to it.
In the sitting area, Martha was examining Jack's bag and pulled out a bubbling container with a hand in it.
"Oh my God." She screamed, and set the hand on the table, while the others came over, "You've got a hand. A hand in a jar. A hand in a jar in your bag."
"Why did you bring the hand?" Luna asked.
The Doctor looked at the hand for a few seconds before realising.
"That's—that's my hand!"
"I said I had a Doctor detector." Jack said as if something like this was normal.
"Chan—is this a tradition amongst your people—tho?" Chantho asked.
"Not on my street. What d'you mean that's your hand? You've got both your hands, I can see them." Martha said pointing to both of his hands.
"Long story. I lost my hand Christmas Day. In a sword fight." The Doctor said remembering when he fought the Sycorax and they cut his hand off.
Luna sat down and relaxed. They got the device working and the girls including chantho were staking circuits.
Later Jack, Martha and the doctor were talking when they heard the door shut.
At the same time on another part of the complex Luna was trying unsuccessfully to calm the professor down, he knocked out chantho nearly killing her. He then turned on luna he picked her up by her neck strangling her she fell unconscious and fell to the floor. Chantho came round and shot the master. He entered the TARDIS just as the others came through the door. Martha ran straight to Luna will the doctor went to the TARDIS. He tried to convince the master to not do anything.
Meanwhile Luna woke up facing Martha. They all crowded round Jack and grabbed his wrist. Next thing they knew they were in 21st century England.
