Opening it fills her with dread, because she knows the light the moment she sees it. Knows it's the Last Light, only gone completely silent and devoid of life, and to walk in is to invite the question of why. But even so, she steps back, turns away from the open door. Reaches for him again.

"Come with me."

Or she will shut that door and tear it down and stay. How long has he really been here, alone? She's always been stubborn. Refusing to listen to actual sense. Willing to fight even if her only weapons are her nails and her teeth and her words.

(What's the point of all the power locked in her chest if she can't use it for this?)
