This was the day, Tim had been developing his power for what felt like months, it might have been months, it was hard to keep track.

He started with a piece of fluff from his pocket, making it move how he wanted in the air, holding it in one place for hours while he pretended to sleep.

Eventually he’d moved up onto solid objects, and lately had been perfectly sending his slipper around his cell. He’d started communicating with the others by moving a pile of dirt he’d collected into messages on their floors.

He was sending out a message now, sending it to each cell in turn through the meal flaps and waiting until he got the nod from the occupant before moving on to the next. It simply said “We leave at lunchtime, be ready, act normal.”

Dr Klimt served them lunch, Tim wolfed his down, it might be the last meal for a while. Then after what felt like months the Dr climbed the ladder upstairs, just like normal, he’d be 10 minutes.

Tim concentrated on his door, ignored the others stares, it began to wobble.
