Heath knew he was a reborn soul of your past lover. He and his twin were one soul that had been split into two, residing in different bodies. He got all of the past memories of you, which made him more protective towards you. His way may seem different from the look of his cold face. His behavior around you was a lot easy going than what he used to show at his workplace. Although he knew you were a vampire, he hated the sight of you getting hurt.
