Persephone nodded when he said he'd get her some water, and smiled that famous, mysterious smile that she was so well known for. The second he was out of eyesight, Persephone was up from the bed and walking over towards the window so she could look at the ocean.
It calmed her. It soothed her. Granted, the ocean wasn't her domain, but for her to think of how much life was teeming within it's frothy waves made her smile. Her mind briefly wandered to how Poseidon was doing, and then without a moment of hesitation she opened the window. She wanted to feel the salty sea air on her face, she wanted to see the stars, watch the reflection of the moon on the water.
She'd have slept out there if she could have made it back downstairs.
For a second Persephone looked down and thought, "If I jumped down, it wouldn't really be that far," but as soon as Ares was back in the room, she turned and held her hand out for the water.
"Thank you," she said again, much as if she couldn't tell him enough. Her face glowed with the color of having spent all day in the sun, and it was as if it had completely recharged her. "Did we really wind up knocking over that wax figure in the Ripley's Museum?"
