Samantha Harris

Samantha, but everyone calls her Sam, was the first of only three beings to ever be born with the serum as a part of their genetic makeup. The others being Samuel Harris and Marie Dixon.

Background
Sam and her brother Sammy are fraternal twins. They were named after their father's favorite cousin Samantha who almost everyone called Sam. When Sam and Sammy were in utero, they sensed the malevolence building in Tim and decided to hide Sammy's presence from everyone, even their parents.

Unlike everyone except Sammy and Marie, Sam was born with her abilities as a part of her genetic makeup. The serums were not present in their system. Their abilities were as natural as their eyesight and their hearing. Like their father, it is believed that they will be immortal. Unlike their father, they will not have to die in order to reap the benefits of their abilities.
