Donna Noble clung tight to the railings inside the TARDIS her hands already slipping due to the sweating of her hands. She looked over at the console to see the Doctor dancing about flipping switches and pressing flashing buttons of all colours. Allons-y? Yes, that's what he said thought Donna.
"What?"
"Allons-y ", he shouted back as cheery as a child on their birthday.
"What?"
"It's just, just a thing"
"A what?" she demanded.
"It's a clever thing for clever people to say", the Doctor said over the wheezing and groaning of the TARDIS
"Are you implying that I'm not clever", she snapped with a fierce tone. To that he dare not answer. He just went back to flying the TARDIS... Badly.
Donna was just about to say something as her grip on the railing failed. Something was throwing the machine around like it was a juggling ball. The lights flickered then failed. They were in a veil of darkness.
"What's wrong with her?" The Doctor said quizzically but worried.
