Sea water came streaming down from his trenchcoat as he stood, the thin patient's scrubs clinging to his skin. Castiel ignored the sand crusting around his feet as he waded back out of the water. He flopped down on the sand, his waterlogged coat squishing under his weight. He smiled up at the Doctor, though he didn't take one of the offered fizzy drinks. When did he come back? Castiel must have been caught in the waves. But that was okay. He seemed friendly and so Cas was content.
He watched Lydia with curiosity as she held the marshmallows over the flames. He still wasn't sure what roasting it was supposed to do, though he knew Dean at least seemed to like food better when it was cooked over a fire. Castiel supposed it had something to do with human instincts that they'd failed to grow out of, always burning away the best nutrients of their food just to keep bacteria under control. Checks and balances, he supposed.
But then Lydia asked if he was fallen, and his contentment evaporated. His eyes turned more hollow, his smile only a ghost of the peace he'd felt before she reminded him. 'You have fallen in every way imaginable.' Hester's disgust and anger were still ringing at the forefront of his memory; he deserved it, he knew. But he still was not ready to face everything he'd done. Not now. "You know... with a neap tide, the gravitational forces of the sun and moon are fighting each other. It's all a matter of angles, really. When the sun, the earth, and the moon form a right angle, it makes the tides less dramatic than a full or new moon would."
