The enormous zap! of electricity feet from him made Rory jump violently and spill coffee down his entire front. He swore loudly at the burning heat quickly seeping into his lap, dangerously close to becoming a terrible situation. A throaty chuckle from in front of him alerted him to his daughter's presence.
"It's great to see you again, River, but I've really got to go get this hot coffee cleaned up." He stood swiftly, and ran down the hallway. "AMY! River's here!"
Jenny unlocked her arm from River's, taking in the house around her. "Where... and when... are we?"
River smiled. "My parent's house, 1942. It's a very long and confusing story as to why they're here and why the Doctor can no longer visit them. I suppose they're your grandparents in a manner of speaking. As close as they can be when the Doctor's your father." Her voice lowered. "Amy may not accept this easily. When I said she'd tell me to smack the Doctor, I was completely serious."
"River!" Amy bounded from the hallway and wrapped River in a fierce hug. "Ooh, we missed you! How are you? How is he? Haven't destroyed any civilizations lately have you?"
"No, mother, nothing wrecked. We're both well. Extremely well, in fact. There's been a new addition to our family."
Amy's eyes widened as she thought about what that might mean. "What-"
Jenny stepped around River then, smiling and waving at Amy amiably.
"Who's she?"
"Her name is Jenny," River said soothingly, hearing the edge creeping into her mother's voice. "She's the Doctor's daughter, but not mine. Only the Doctor's. She was created by a progenitor machine sometime ago-"
"His daughter?" Amy nearly shrieked, making both of the other women recoil slightly at the Scottish accent.
"In a matter of speaking, yes," Jenny stated bravely, still standing behind River. "I'm technically a clone of something he could come to be or have been. It was not his fault. Please don't smack him?" She had meant that last sentence to come out as a request, not a question, but the fierce look creeping over the redhead's face was slightly frightening her. Rory had reentered the room by then wearing clean clothes, slowing to a confused halt upon seeing the situation.
"Did I just hear 'the Doctor's daughter?' River, did you and the Doctor have a baby?"
River chuckled. "No, Dad. She's a clone of the Doctor, sort of."
"Gene shuffling?"
"Exactly," Jenny piped up. "If we're on Earth in the 1940s, how do you know that?"
Rory was slightly taken aback by the question. Usually they didn't have to address the terrible events in Manhattan much. "We were originally from the 21st century, but we were sent back in time and now we're stuck in a paradox." He tried to shrug noncommitally. "I know a lot about 21st century medicine, I'm a nurse. And you're obviously not an exact clone. I've seen a couple of those before."
"Well, you're taking this a lot better than your wife is," Jenny commented, pointing at the frozen and angry Amy.
"That happens a lot. Amy, it's alright."
She glanced at her husband. "Oh, I know. River?"
"Yes, mother?"
"Smack him for me."
