If you even so much as make her frown, I swear I will curse you, you hear?
If those asshats come after you I will be their curse. You have earned this blessing, they have already taken more than their share. Either they are with you or they are against me. That's the way it is.
Every blessing comes with a curse. That can be with one person or split between two. Assholes take the blessings and pass the curse onto others, that's power abuse. Good people take on their fair share of curse or more in order to bless others. Thus when an angel steps from the shadows to save others they come with an angel-monster. Anyone who tries to curse the angel gets monstered by the angel-monster, the protector. Thus curses aimed at the angel rebound in magnified form. The angel-monster takes the magnified blessing and keeps care of the angel. Another way to say this is the good shepherd the crook - it's the only way this can work.
Her experience of madness made her a savant. The curse was huge. The blessing was huge. That is the way of the universe. That is the "magic." She paid for it so she could give to others. How about you make her life a little better?
