The next few days for Cas were a blur of furtive glances, small smiles and secretive glances between him and Dean. All days for Cas were blurred- being alive for as long as he was made the days and months, decades and centuries and millennia go by relatively quickly. But some moments seemed to slow down now, a new emotion emerging. Something light yet deep and frightening, soft and strong and raw and full of energy. And that was love.

He had watched humans for thousands of years, but never before like he watched Dean. He saw how the light fell glowing onto his face, how his lips curved up in a light mocking smirk when he was being sarcastic. And his eyes, a flawless green, how they widened ever so slightly when he looked at Cas. His lips were perfectly rounded and full and his voice always lowered and become rough, yet gentle, when he talked to Cas.

Castiel didn't understand about being straight or gay, homosexual or bisexual or not. He just felt that Dean had come home, had found his place with Cas. Cas hadn't understood why Dean had rebuffed Cas so much when they'd just met. Really, Castiel was genderless. Angels weren't 'biological' and therefore had no sex. It never occurred to him that Dean might've been more willing if he'd chose another vessel.

The place he had taken Dean was in his mind, like a dream-world that was only accessible through unconsciousness. It reflected his feelings and emotions and created a seemingly unbreakable world inside his head that he could bring others into.

He was still desperately worried about losing his grace. Cas thought about something Dean had said, I'm shit at feelings. Was that what these were? Feelings? Emotions? He wondered briefly what had happened to the righteous soldier Castiel who'd been emotionless and unaffected by the human state of mind. But he didn't want to care about that now. He wanted to care about Dean. He wanted to care for Dean until everything was dark and gone.

"Cas? Hey- um- Cas- are you listening to me?" Sam tentatively tapped Cas. Cas reacted in an instant. He threw Sam across the room and didn't even look up as he hit the wall. "Dammit, Cas!" Sam said, picking himself off the floor. He was sporting a bloody nose and a limp as he staggered across the room back to Cas.

Castiel hadn't realized it was Sam, having been so lost in thought. He was brought back to the present now, and turned to Sam. "I am sorry. Are you alright?"

"Yeah, s'okay… just came to say that Dean wanted to talk to you… he's in his room-" But before he could finish his sentence, Castiel had disappeared. "-he was busy, and wanted me to get you…" Sam finished and touched his nose gingerly, wincing as he found blood.

They were at Bobby's place since it seemed like a good idea to regroup. Nobody could find any cases, and Lucifer seemed silent, so it looked like they were crashing at Bobby's for the weekend. Castiel was sticking around, and Sam thought he had an idea why…
