Just Like Old Times || Doc, Rose, Jack, Donna
He had a ... gang. Team. Squad. It was at once familiar and at once all new and different, and reminded him almost painfully of their first (and last) adventure together on the Dalek Crucible. And that adventure had involved dimension hopping as well. Hopefully, this one wouldn’t end up in tears for all of them.
He’d been deliberately vague when the Doctor had asked him whether he intended to use the dimension cannon, because ... who was he kidding? He was dying to try it out. If nothing else, the possibility of adventure and somewhere new was practically eating him alive.
He had checked the cannon before agreeing to the jump - and as with anything constructed by the Master, it was a brilliant piece of work. He’d even come up with a work around for the problem of dimensional collapse by targeting existing cracks in the universe walls - which minimised the amount of damage caused by their passing through, but also meant that navigation was going to be a particular challenge.
“There is a return switch,” the Master told them, handing them familiar looking yellow discs that made Doc wonder if the Master had been spying on him and Rose, back in the day. “But it takes time to recharge, and you need to be in the right place - close enough to the dimensional crack - to trigger it. I’ll be in touch via a communicator, but you know how those things work when you’re jumping between universes.”
Fingering the yellow disc, Doc nodded at the rest as the Master powered the system up. “Well,” he said, grinning at them, reaching out to take Rose’s hand. “Here goes nothin--”
There was a loud zap and a clap of thunder, and the interior of the bank disappeared to give way to ...
Forest. Dark, damp, dripping forest, as far as the eye could see.
