Title: Gearbox (The Won't Miss a Piece Remix)
"Where are those snowshoes?" asks the Doctor, on another day. "We'll be landing any moment now."
"I've found five snowshoes, all different sizes, and half of a tire," says Ace. "Listen, do you ever clean this place?"
"No," says the Doctor. "The last time I did a bit of spring cleaning, they wanted me to actually get rid of the dust! Imagine, just throwing dust away, as if it were useless."
Ace's lips quirk, and the TARDIS stalls and her lights go out, one by one. Ace’s smile dims to match. The Doctor sighs and pulls open one of the bulkheads.
"What's happening?" asks Ace. "Need more gears?"
"The sparkplug's burnt out," mutters the Doctor. "Look."
Behind the bulkhead is a gap, half-filled with a tattered piece of molten rubber. The Doctor prods it, gently, and the rubber crumbles into ash. Beyond it is a seething hole of electricity, sparks jumping in and out, beginning to escape.
"I've seen sparkplugs before," says Ace. "That's not a sparkplug."
"Correct," says the Doctor. "It is a pile of ash. But it did used to be a sparkplug."
