Synopsis: The other Amy reveals that she is from a few moments in the future, and is able to come into the current outer Tardis because "the exterior shell of the Tardis has drifted forwards in time". The other Amy knows what to say and do because, from her perspective, she is repeating what she heard herself say earlier on. The Doctor sends the current Amy into the Tardis within the current Tardis, in order to maintain the timeline. However, not long before the current Amy is gone, another pair of Rory and Amy walk in through the door of the outer Tardis, explaining that the Doctor, from their perspective, just sent them into the inner Tardis. The Doctor promptly sends the current Rory and now current Amy into the inner Tardis. The Doctor then explains that he will set up a 'controlled temporal implosion' in order to reset the Tardis, but in order to do so he must know which lever to use on the control panel. Moments after he speaks, another Doctor walks though the outer Tardis door and tells him to use the wibbly lever, which he quickly pulls, then runs and steps into the inner Tardis to tell his past self which lever to use. The inner Tardis dematerialises while the outer Tardis does the same, and the Doctor assures Amy and Rory that they are now back in normal flight, and then advises Amy to put some trousers on.
