Baby Elkins

Child of Missy Elkins, born in Lost Harbor.

Baby Elkins was delivered and then abducted by Dr. Harold Gillespie. At the end of season 1, this baby was being fought over by Daughter Dooley and Horned Head.

I really cannot overstate how important the spoiler warning at the top is before I go further.

Seriously.

I'm putting it in again just to make sure.

In season 2, it became clear that Baby Elkins was less a "baby" and more "a living vessel for the power and will of Those Who Sleep Beneath". When Daughter Dooley smote Hornéd Head and picked up Baby Elkins, it tried to take her over. Daughter Dooley fought the child for seven years. The two were entwined and became The Dead Queen.

Daughter Dooley is free six years out of every seven, but the year before TDQ's binding is renewed, she must return to the grave where TDQ is bound and stay there.
