I shouldn't be making excuses for her dumb ass, but she got a problem. A gift some folks call it. She can hear everyone's thoughts. All the time. Thought she was crazy when she was younger.
She can't read his, or any of the vampires, cause technically they're dead. Ain't nothing to read when they're dead.
So I can see where it would be enticing if folks just won't shut up in their heads, and she can't turn it off.
