Edward Eric has no control over his trust. It's a deep-set problem, one that he gained in the Gate. After all, two souls aren't worth two limbs. He had to give something else up. His trust. Or his ability to control it, at least.
And once he trusts someone, he can never, ever stop and never, ever hurt them. He is completely defenseless.
AU where Trisha's soul was brought back, but wasn't compatible with the body that her sons had made and went straight back into the Gate.
