...lol. Canon is a bit vague, basically Goldilocks went through a very traumatic bear related experience and her mind simply couldn't cope with it. She became violent and aggressive, which eventually developed into a kind of DID multiple personality thing with the bears. Then she went to Ever After which didn't help because they ran terrible experiments on the kids that involved mind rape and pain and they had machines that brought the dead back to life so they really didn't care much about the damage they did to the kids bodies. I should mention that in Goldi's canon fairy tales exposed to great trauma exude grim energy, which is a fantastic power source Doctor Crooked wants to study. SCIENCE!! Again her mind simply could not handle it and so she started repressing hard, she can't acknowledge terrible things that happen or else she goes into a very cold and distant state that can end in bear maulings. There's some paranoia and psychosis mixed in there too, with the visions of bears thing, girl is a mess.

How's Izumi coping with her students being here and Ed being all murdercavey and old?
