Eli was adopted when he was eight years old. His mother had abandoned him for days, he was malnourished, and neglected. He never knew his father and he never saw his mother again after he was taken. I have that he has begun searching for family and is eager to get to know any new siblings. In all reality, she could be a full sister since he never knew who his father was and he suspected his mother had another life anyway. If she were a full sister/or a new half sister on his mothers side, she would have to be under 25, but if on his fathers side any age.
