Neville stopped smiling. Oh, this was going to be tougher than he'd thought. He knew that look all too well. "Ginny. Dear, I'm sorry, but- we're not home. And we can't get home. No one can. All over time and space, people are being pulled out of their lives and brought here. I was trying to apparate home and thought I'd just overshot it like I do when I've been drinking. I met a man who was born and raised on a spaceship, and he's got magic but it's really just "psy-ence". This place, it's trapped people here. Look, what year are you from? Later than 2006, I'm guessing, since you've got three kids now. I'm from 2006- Harry, Ron and I had a pint at the Three Broomsticks and then I was here. Did I go missing in your world? I doubt it, since you didn't seem shocked to see me. That must mean we get back right where we left off, do you see?" Neville wasn't a genius, but he'd had a month to sort this out.
"I know we saw them. I helped carry Lupin's body. I remember, how could I-" He took a deep breath. He couldn't think about the war. He needed to stay free from emotion, he couldn't get all choked up. "Ginny, I know, okay? But I promise you, I met Harry's mum. I met her. I shook her hand, I bought her a cup of tea. I told her about him- she hasn't even married James yet."
He put his hands on her shoulders and then pulled her swiftly into a hug- he didn't know if he was trying to comfort himself or hold her steady in case she tried to hex his face off. "I promise the kids are okay, alright? But right now, you and I are stuck in a bizarre time thingy and you are in your robe at night on the streets of a city. Can we please go back to where I'm staying?"
