"Epsilon 5!"

The TARDIS console room glowed a faint orange from the central time rotor in the room, which slightly bathed the Doctor's white hair and velvet cost. He was scribbling notes on a blackboard with chalk, solving impossible equations. "The trees there are made of silver. Perfect picnic spot, minus the carnivorous humanoid species that lives there." He jumped down the flight of steps, quickly approaching the side of his companion, Clara. "What do you think?"

Clara met the Doctor's child-like enthusiasm with a calm expression. Normally it would be the other way round, but the Doctor hadn't left the TARDIS much after she needed repairs. She placed the book she was reading down on the console, revealing her eyes the Doctor decided we're just too big for her face. "Let's see: on one hand, carnivorous lifeforms; on the other, my Year 9 class." Her northern accent coupled with her humour and charm made the Doctor smile. "How long 'till we can get to Epsilon 5?" she asked.

As the Doctor began pulling levers, the TARDIS gave an almighty jolt, causing both of them to lost their balance and tumblr across the console room. The Doctor quickly grabbed his monitor screen, reading the Gallifrayen writing flashing on it in sync with the alarms. "Oh dear."

"What's 'Oh dear' for, Doctor?" She asked as if he was one of her students.

"We're going a bit further than Epsilon, I'm afraid Clara."

"How much further?" she asked assertively.

"Oooh," he replied calmly. "Around about... A different universe."

Clara gave her shocked-and-annoyed face. "Another universe? Doctor-!"

"Yes yes, I know," he reassured her just as the ship made an almighty crashing sound, followed by science. "There we are, see Clara." The Doctor breathed deeply, calmer. Suddenly, all of the machinery, including light and heat, were broken inside. "The bad news is... We're stuck here for a little while."

In Charles' office, the Professor was teaching Physics to some more intellectual students, before becoming suddenly distracted by a loud crash in the front. He placed his two fingers on his forehead- 'someone is here.'
