When the Doctor, Rory and Amy found an aged Rory living in a New York hotel. The hotel is a battery farm for the Weeping Angels, where Rory will be sent back to at some in the future. Sent back to without Amy. Aghast at this being his fate, Rory decides to flee. If he can alter time, the paradox would kill the angels. Guided to the roof, Rory saw that there was only one way to escape the angels. He had to leap off the side of the building! Amy wouldn’t let him, but they decided to leap together, not wanting to live without each other.
Fortunately, the plan worked, and they survived. Their happy ending was snatched away from them as a single angel survived, and Amy was forced to choose between Rory and the Doctor. Amy followed her heart, breaking both of the Doctor’s in the process.
