Rory Williams staggers outside of the TARDIS just after being saved by yet another miracle and paradox. Amy, River, and the Doctor fly into the TARDIS, discussing their next trip but Rory lags behind.
"Amy!" Rory calls, looking down at a gravestone, "Come see this."
Amy emerges from the TARDIS doors calling, "What?"
"There's gravestone here for someone with the same name as me," he says nonchalantly.
Amy saunters out of the TARDIS, indulging her husband.
"What?" Amy says, laughing, looking at the grave then back to her husband.
Rory blinks twice, looking up at Amy, confused. A near second later Rory vanishes and an Angel takes his place. "Doctor!" Amy yelps, hopelessly, terrified.
The Doctor and River run out of the TARDIS towards her, but she does not turn. She keeps her gaze fixed on the angel. "Where the hell did that come from?" River Song bellows, keeping her distance.
"It's a survivor," the Doctor says, brandishing his sonic screwdriver, "Very weak, but keep your eyes on it."
Amy does as she's told, carefully squinting at the Angel, still shocked that Rory's gone. "Where's Rory?" she asks.
The Doctor walks toward the angel cautiously, knowing full well what has just happened. He looks to the gravestone only to make double sure. He shakes his head, barely noticeably, and says, "I'm sorry," he breathes, "Amelia."
"I'm so sorry," he adds.
Amy's world shatters. Her lip quivers. "No. No we can just go and get him in the TARDIS. One more paradox," she lies to herself, in denial.
"Would rip New York apart," the Doctor starts.
Amy interrupts him, "No that's not true."
"I don't believe you," she adds, panicking.
"Mother, it's true," River says solemnly, defeated.
Amy's breaths are getting increasingly more shallow. She starts for the angel, "Amy, what are you doing?" The Doctor asks.
"That gravestone, Rory's, there's room for one more name isn't there?" she asks, breathlessly fast.
"What are you talking about?" The Doctor says, grabbing Amy's arm, trying to lead her away, but Amy breaks his grasp, "Back away from the Angel. Come back to the TARDIS, we'll figure something out."
"The angel, would it send me back to the same time," she starts, face beginning to scrunch up, "to him?"
"I don't know," The doctor says through heavy breath, terrified Amy will do something rash, "Nobody knows."
He reaches out for her again but she moves closer to the angel. "But it's my best shot, yeah?" Amy asks, not really expecting an answer.
"No!" the Doctor groans.
"Doctor, shut up!" River snaps and yells, "Yes it is!"
Rather than lie to her mother River does everything she can to help reunite Amy with Rory. She can't bear to see this happen to her mother.
"Amy!" The Doctor says.
"Well then," Amy sighs, at the same time as the Doctor, "I just have to blink, right?"
"No!" the Doctor bellows, his voice filled with anguish and fear.
"It'll be fine. I know it will," Amy starts, "I'll-I'll be with him like I should be."
"Me and Rory together," she says, desperate to be with him.
"Melody," she calls for River, addressing her by her given name.
"Stop it!," The Doctor yells, "Just stop it!"
Amy reaches he hand behind her back towards River. She grasps her hand in hers. "You look out for him," Amy says chocking back forming tears, "And you be a good girl and you look after him."
River looks up at the Doctor as he says, "You are creating a fixed time," through gritted teeth, "I'll never be able to see you again."
"I'll be fine," Amy says, starting to cry, "I'll be with him."
"Amy. Please. Just come back into the TARDIS," the Doctor pleads with her, adding, "Come along, Pond. Please."
Amy weeps, still not looking away from the angel, knowing the Doctor's right. It's time for her to finally choose: The Doctor or Rory. Though it may break her heart either way, her mind is made up, "Raggedy man," she starts, then turns to face him, "Goodbye."
Amy fades away into the angel, transported in time. The headstone now reads, In loving memory, Rory Arthur Williams, Aged 82...And his loving wife, Amelia Williams, Aged 87.
As Amy fades away to the Doctor, she is transported in time of unknown date. She looks around her, eyes burning with tears, hopeful that she sees her Rory. But she doesn't.
She runs up the hill, through the graveyard toward the spot they had picnicked in the day before. "Rory," Amy breathes, barely audibly.
Rory looks up at his wife in disbelief, "Amy?" he starts, "How?"
"Shh," Amy says, putting her finger to his lips, "Together or not at all, remember?"
