At this point it's at least implied canon that Liet was forced into an adult role young and then had a really fast growth spurt and suddenly a teenager. Like I think he had two centuries from when we see him as a young kid and a mid-teen. Dang, boy. This also means he's been a teenager for a minimum of 600 years and it will never stop being the funniest thing about him, never.
Liech was pretty much spoiled and doted on and everyone's favorite little sister but at the same time she was really shy of strangers and almost entirely dependent on other people. She did absorb some of Austria's tastes and manners, though. I figure she was emotionally mature at a young age and yet all her physical needs were provided for so she was still very young in that sense.
ooc /this is like a mix of canon and hc shhh
