Do You blame yourself?

Well its quite common in this situation for a patient to feel a kind of guilt

The accident

It's really funny isn't it?

HAHAHAA

Do you really think they care about you after everything you've done?

Error is mostly seen with a giant smile it haunts people's dreams shape-shifting into the people it's victims love mentally and emotionally torturing them it seems to find great pleasure in this. There has only been one instance where it has been seen frowning when one of its victims hadn't  been afraid of its manipulation.
