Delphine knows she hasn't much of it left, but while the tiny not-Delphine settles in, she's using her time. This– this thing she's done– could take her right to the top– or the bottom– of the chain. Or she could be killed. But that's inevitable. Meantime, being the host has its privileges, and she's determined to use them, as long as she can, for her own purposes.
She never forgets that Cosima is sick. Cosima is dying, and all her sisters are under attack. Delphine will prolong their lives, by any means necessary, including her own demise– one way or another. And it is possible, maybe, that the tiny life inside her will make it possible for her– her body, anyway– to survive.
Cosima, in her thoughts, Cosima, branded into her mind, into her heart, Cosima, sealed to her lips, Cosima will know. Even near-death, Cosima's curiosity drives her to seek out information. If only she will follow the breadcrumbs Delphine has laid out for her.
Footsteps echo in the garage.
Delphine senses not-Delphine struggling to assert itself. But Delphine turns. Delphine faces her future, the consequences of her actions, the end of her life as she knows it, alone.
