She's definitely not 13 in that picture. She's probably not even 13 in her earliest orphaned appearances. She doesn't have curves until >>280793605, which has to be years after they're first orphaned considering how different she looks. She's probably supposed to be like 8 in >>280793409 and Yuri is the world's tallest one year old.

I doubt Yor even started high school. She couldn't have been more than 11 or 12 when they were orphaned.
