"The entire universe is up for grabs; we can travel to anywhere at any time at all, and you decide you want to go to Ancient Egypt?"
Windsor was dumbfounded by his flatmate's choice of destination. They could see the future, meet dead celebrities, and Truman wanted to go into the middle of the bleeding desert.
"I always wanted to visit the pharaohs and see the tombs and how they lived! My screensaver is the pyramids, Windsor! You know this!" Truman defended, showing Windsor his phone as proof.
The Doctor grabbed the phone from his hand.
"That reminds me," he said, waving his sonic screwdriver up and down the phone before tossing it back to Truman, who fumbled with it until it clanged on the floor of the TARDIS. "Universal roaming. Now we can contact each other in case SOMEONE," he glared at Windsor, "decides to wander off."
"Look, it was one time!" Windsor stated, tapping on the TARDIS console.
"Would you stop that tapping! You're giving me a headache!" moaned the Doctor. "And besides, Ancient Egypt is a fantastic time! Marvelous people, the Egyptians. I've wrestled dinosaurs with Queen Nefertiti, played checkers with the young King Tutankhamen, and don't get me started on those slaves that built the Sphinx. The stories they have…" he smiled and flipped a few switches on the console. "Besides, Duke of Windsor. You get next pick."
This seemed to satisfy Windsor, who gave Truman a triumphant smirk. The TARDIS rocked as they slipped through the timestream, passing unfathomable wonders and unspeakable horrors to reach their destination.
The Doctor stepped out into the bright Egyptian sun and looked around. They were somewhat off course, but the half-completed pyramids were just over the horizon.
"GAHH!" Windsor yelled as he entered the light. "I can already feel my sensitive skin roasting alive."
"Oh, shut up you ponce," Truman laughed as he rubbed sunscreen on his arms and face. "Fancy some suntan lotion, Doctor?"
"Nah, I've never needed it," he replied. "Funnily enough though, I should have skin cancer from the amount of suns I've been in contact with. Chalk it up to Time Lord physiology I guess. Well we have a bit of a walk ahead of us gents. Shall we?"
"Can't we use that motorcycle I saw parked near the billiard room?" whined Windsor.
"And get sand in the spokes? Do you have any idea what that'll do to the transmission?" the Doctor exclaimed as they began their journey. Truman adjusted his wide brimmed sunhat (Windsor had teased him about it in the TARDIS) and looked over at his suffering friend. This was clearly not his territory.
"The sooner we get out of here, the better," Windsor complained. Suddenly a shadow fell across him. In fact, it fell across everything in the desert.
"Did the sun just set?" asked Truman, looking at the Doctor for an explanation.
"It did more than that," the Doctor began, his cheery demeanor vanished. "It disappeared!"
