Doctor Who: The Eleventh Doctor: Time of the Odd

Alice went back home to pick up some mementos from her flat – photos more important that ever now that a big chunk of her memories have been stolen by the Sapling. There, they discovered that the flow of time had been shattered: every moment in time existing only in space, simultaneously. Earth became a giant ribbon looped around the sun: you could walk down the road to last week, and drive decades into the future or past. With the help of Alice's neighbor, Kushak, the TARDIS crew found the source of the trouble in 1968, and put a stop to it – with the (terrifyingly sudden) assistance of the Sapling. Planet Earth was restored… but do the Sapling's actions prefigure something more sinister?
