How does she know how to converse? And speech? Vocab?? Memories inherited from mom?

I mean one of the reason she would know is probably from the animals? Maybe? Idk

I think .. the guy with the blue hair comes every winter to take care of her .. as you can see he was in ice ... And would break free from it every winter

I believe that her mom actually

nah her mom died at birth

She inheritances part of her mom's memories, so she might be able to have conversation because of that, even tho, her speech is odd.
