This starts in the graveyard after Rory asks if they could go to the pub next time.
DOCTOR: Next time? What do you mean next time?
*Amy, Rory, and River look crestfallen*
DOCTOR: Me, I want to go to the pub right now!
He proceeds to comment that he loves video games.
AMY: We’ll let you have a go. Long as you’re paying.
RORY: You are so totally paying.
AMY: Epic levels of paying!
DOCTOR: Paying, absolutely.
AMY: Yeah, the Ponds and whatshisface.
DOCTOR: Just remind me, what does one generally pay with?
After Rory is zapped back again and they see his name on the gravestone, the Doctor told Amy how sorry he was.
DOCTOR: Rory’s dead now.
Amy insists they go back for him in the TARDIS.
DOCTOR: No. Because we didn’t. It’s written in stone.
Amy points out there’s room on the gravestone for another name.
RIVER: You’re right. We don’t know what the rest says, so it’s not written in stone yet.
DOCTOR: What are you talking about?
Amy asks River at the same time if the Angels would send her back to the same time Rory is at.
RIVER: Probably, they tend to work on fixed cycles.
DOCTOR: IT’S NOT GUARANTEED!
Amy insists she’ll be fine and be with Rory again.
DOCTOR: This is stupidly dangerous. Don’t do it.
RIVER: It’s the only way.
Amy tells her daughter to look after the Doctor.
After Amy goes back to the past and we see the name on the gravestone, there is more with the Doctor and River.
RIVER: She made it.
She takes the Doctor’s arm and tries to guide him back to the TARDIS, but he’s staring at the angel.
RIVER: Come on. She’s gone now, Doctor. Amy’s gone now.
The Doctor breaks free from River’s hold and strides up to the Angel.
DOCTOR: What about me? Gonna take me now?
RIVER: It’s weak. I think it’s done for now …
DOCTOR: Tell your friends. Tell all the Angels. Next time I see you, I will grind you into sand. I will make a desert of you!
RIVER: Doctor, stop it!
He pushes past River and strides into the TARDIS. River follows.
After the “one psychopath per TARDIS” exchange …
DOCTOR: I’m not a psychopath!
RIVER: You will make a what of the Angels? A desert, did you say?
DOCTOR: The Angels deserve it.
RIVER: Are they the only ones, or do you have a list? Don’t travel alone, Doctor, because I’m honestly worried where you might end up.
