Cary Loudermilk

Cary was born nine months after his "sister" Kerry, to a woman named Erma but from different fathers. When Cary turned 8, Kerry appeared in his room and the two have been close ever since. Kerry can merge into and emerge from Cary's body, and only ages when she is separate from Cary. Cary is a trained medical technician and engineer, and handles much of the boring day-to-day routine of their life.
