The Doctor returns from another night out with River Song. Amy, wide awake and sitting in her nightie on the stairs, catches him. She convinces him to tell her what he does while he's out at night, then tells him why she is finding it hard to sleep lately because her life doesn't make any sense. Due to the events of "The Big Bang", she can remember two versions of her life, one without her parents and one with. The Doctor comforts her and reminds her of the saddest moment of her life. It was at a fair when she dropped an ice cream. While recalling the event, she suddenly remembers a woman with red hair, dressed in a nightie, who gave her a new ice cream. When she finishes the anecdote, the Doctor is by the doors, ready to go with her to the fair.

Right before attempting mouth to mouth resuscitation, the Doctor finds that River is merely holding her breath, and had been chased by Sontarans. As he chastises her, she notices the gold dress he chose for their first visit to Caldoron Beta five years before, hanging near the console. This incarnation of River is wearing the vortex manipulator, placing the events after "The Pandorica Opens"/"The Big Bang" from her perspective. She demands to know whom he's brought, and storms up the stairs to find the hussy. An instant later, the first River returns from the TARDIS wardrobe, demanding to know whom the Doctor talking to; she returns to the wardrobe. The second River returns, demanding to know to whom the Doctor is speaking. When he denies talking to anyone, she resumes her hunt. A third River enters the TARDIS, actually wearing the gold dress. This version of River was expecting to meet the Doctor here, but on seeing an identical gold dress hung by the console, asks why he has bought another. The Doctor asks her to step outside to check if the light on top of the TARDIS is working.

The youngest River reappears, certain she has heard voices. The Doctor tells her he was talking to himself and she bustles off again. The second River returns to the control room, likewise convinced she heard the Doctor talking to someone. The Doctor brusquely activates her vortex manipulator to send her back to prison. The third River re-enters the TARDIS, followed by a second, older version of the Eleventh Doctor, who informs her that she is in the wrong TARDIS. As they are about to leave, she tells the younger Doctor that they are off to see the Singing Towers of Darillium. The two Doctors share a brief, sad moment, knowing such a trip would possibly be the most advanced (in total age) Doctor she would see before she dies in the Library ("Forest of the Dead") in the Tenth Doctor's presence.

As the older Doctor leaves, the youngest River returns to catch a glimpse of the Doctors together. She asks the younger Doctor about it but he refuses to tell her, using River's catchphrase, "Spoilers". River jokes that his secrets will be the death of her and walks past him. The Doctor pauses to have another sad moment before taking the youngest River on their date.
