A lot of people are arguing about her mental capability being restricted by her brain's biological capabilities. Which is ridiculous because it is not consistent in the story. She oh so convieniently remembers what she needs to about the novel because of plot. But then she's mentally a five year old even with her memories. Nuh uh. If her brain really couldn't cope because of her physical age, she shouldn't have been able to retain her memories when she was a newborn anyways. Babies aren't capable of long term memory at that age.
