Hera drops the droid head, the light from it skittering off across the floor, as she dodges out of the way of the blaster. Without the light, she can't see where the blaster hit, or landed, nor does she know for sure where Thrawn is or if he'd moved out of the way in time.

From the sound of it, the droid hit something.

Her first instinct is still to go after the blaster, before she has the time to think, to realize he threw the blaster at her, and what that has to mean.

Instead, she moves away along the floor, toward the light from the fallen droid head.
