After the offer was made and accepted the tension between then seemed to melt away. they walked in companionable silence, and Spike directed Cas to the restroom with a quick thumb point and a "lou's in there" as they arrived.

While Cas was washing up Spike tried to get comfortable, but just couldn't seem to. He'd been talking and politicking all day and his one shot at some action was turning out to be, while interesting, rather calmer that he'd expected. He needed action, he needed a thrill.

Cas washed his face and rinsed his mouth out, careful to avoid looking in the mirror. He was excited to bask in the glow and trick himself into reliving better times. He could still remember the feel of it, hot and strong and jagged, as he placed it into the once mauled body. He knew each molecule from another and had felt for himself the strength surging through it, His soul. The one that was so similar to the one in the next room.

As Cas walked out of the bathroom Spike threw him a beer,that he caught without a flinch.
"So, I must admit I'm wondering what could clip your feathers."
Cas was quiet for a minuet, and if spike were one to worry about manners, he might wonder if he'd offended him.
"It was a choice."
Cas finally decided on.
"oh-kayy" spike drawled slowly
"But why would you choose this mud ball over the streets of gold and unicorns and houses made of clouds?"
Cas let out a truly amused laugh then a sigh.
"Well firstly, it's less of a fairytale and more of a barracks for us who were soldiers." he said with obvious distaste
"and as for why… why would someone who had lived centuries without guilt, building a reputation of reveling in torture and pain, choose to have every misdeed laid at his feet at once?"

Spikes eyes widened as he understood
"Ahhh you "fell" for a bint."

"Not quite" castiel smirked behind another tug of beer.

"Oh! Oh, I see… you bat for the other team, can't imagine that the holy rollers were pleased with that tidbit."

"they are utterly indifferent to sexual orientation, it was humans who demonized different forms of love. No offense"

"Then what was the problem? I mean you were an ANGEL for Christ sake. If it wasn't against the policy upstairs, then what was it?"

"Oh I never said it wasn't against the policy, just that gender had no bearing on their opinion. They had plenty of problems with my choices, none of which am I drunk enough to discuss at length." Cas stated, digging in his pocket for his bottled rainbow.

"Cheers to that"
Spike said getting them both another bottle

"I must admit I'm surprised to meet you. None of the prophesies ever alluded to you being around this long." Cas said looking quizzical.

"Oh I was never much for doing what anyone expected. Always have fancied myself a rebel"

"That's a dangerous quality to have." cas whispered gruffly, with a haunted look on his face.

Spike shook his head "Not nearly as dangerous as following the path of least resistance! Like you said, I've outlived my expiration date." Spike crowed smugly.

"But is it really worth it?" Cas asked more to himself than his drinking partner "I mean what does it even matter! We keep forestalling the inevitable! Eventually the world will end. eventually the people we "save" will die. And for what? 70-80 years, tops! What is that? That's nothing! It's a blip, an instant, and then their gone, and I don't even know where they GO anymore!" Cas was nearly screaming by the end.

"I'm not really big on the philosophizing, precious moments. But I figure it's so they can keep the world turning, inventing things, running powers plants, makin' beers, and we can keep comfortable. Also so we can sleep without the nightmares, the worst of'em anyway." Spike said, then he stopped and got a very confused look, going over what Cas had just said. "Wait watta ya mean you don't know, I know Hell's waitin for me, been caught in it's throat a few times. And heavens real, you prove that, and I've known others who've been, who are there now! Finally getting what they deserve!"
Spike snarled.

"I'm sorry I can't ease your concerns."Castiel apologized quietly "but a few decades ago the way into or out of either eternal plain was altered, and I have no way of knowing how souls find their perpetual end since."
