Thoughts on younger Maria and Georg?

No they wouldn't want to kill each other. Georg is ever the gentleman and Maria always sees the best in people.
In reality, Georg joined the navy at fourteen so there would've been some element of that. The womanizing I'm not really sure (I'm not the person to ask)
It's hard to say what would have been there between them in this situation, but if we are assuming there is something, I think Maria would notice, even if she can't exactly identify it. She isn't clueless, just inexperienced. Given her home life I think she would definitely be wary of men like Georg, but not immediately afraid. And she would definitely have the outspoken nature.

That's my thoughts anyway! I hope that helped. It sounds like an awesome story.

It definitely helps! I think after reading what you wrote and thinking about them, I'm leaning more towards them being shy around each other at first. It's kind of a weird story concept, which I guess I could just explain and that would be easier?

So, I watched a documentary about Hitler's obsession with different legends and using those legends to further Nazi technology and one of them was his obsession with the fountain of youth. I thought it would be a lot of fun to write about if somehow during their escape, Herr Zeller (unauthorized) took what he thought was a drug to knock people out with the intention of using it either on Georg (to take him) or on Maria (as a potential hostage), but he messed up and accidentally dosed them with an early experimental version of "the fountain of youth" and they were reverted back to their teenage selves with no memory of each other and the children (and Max and crew) had to deal with them and figure out how to change them back and how to get out of Austria.

That was the longest sentence ever. Sorry about that! Anyway, I suppose I'm trying to find a balance between everyone around them knowing their history and their personalities while they meet for the first time as completely different people? It's a work in progress. It's turning out to be a lot of fun, though, so I hope it comes together!  

All I know is that 16 yr old boys of Georg's background who are dead set on joining the military aren't usually that into girls until they are older...or perhaps their social skills are so underdeveloped they don't have the wherewithall to communicate with them, so he might have found her interesting, but I think it is unlikely they ever even spoke!

I don't think they would have killed each other at 16. Georg is the way he is when they meet in the movie because of his life experiences and the same goes for Maria. At 16 they haven't had all of those yet so Georg isn't going to be as strict with nose in the air kind of thing because he isn't hurting from losing a wife that doesn't exist yet, if that makes sense. We kind of get a small glimpse of his lighter side in the movie, but a very small glimpse of what he may have been like before Agathe's death. It definitely would have been different.
