Same point either way, but here.
Actual is when she was born. Emilia was basically cryogenically frozen through magic.
So she didn't live through any of those years or age physically. It's like goddamn time travel. If you suddenly ended up 100 years in the future, you would suddenly be a centegenarian, regardless of your physical age.
Because isn't how smart your brain should be decided by the physical development of the brain? Like, since she ages slow, shouldn't her brain adapt slower as well?
Also in response to OP, below average IQ but not retarded levels.
2 reasons possible :
- she is half elf. Half elf has longer lifespan but their mind age slower than human because their brain are developping slowly. Like why some animals can hunt just after being born while human cant do shit for years.
- memory loss. She loss all her memories when she was 5. So she only have 14y of memories
Research has shown that being suspended in a cryogen chamber would result to memory loss of the most recent information stored in the hippocampus. She literally lost her most recent memories, making her revert back to a younger mental age.
That didn't stop aquafags either.
