[Alastor is silent for a long moment, just staring at Lucifer with an unreadable expression. Finally, after what seems like forever (but is really just a few seconds), he tosses his head back and laughs. He laughs for a few seconds before it trails off and he wipes a tear of mirth from his eye]

Oh!!! Oh my... Now I see where Charlie gets it from. Such silly, wacky nonsense! Hooooooo. [a hand flap that becomes him fanning himself] If the almighty wanted you and me and the rest of the little thorns in his side out of the way, I'm sure he'd just send down one of your brothers to deal with us. Ha... Making an entire alternate universe as a cage. Foolishness. [he waves his hand dismissively and turns back around to keep walking.

But.

Despite his words, the idea sticks in his brain, like an annoying piece of lint on a fine coat. It was completely ridiculous... It would be so much work for gnats that an Archangel could swat in a moment. Even Lucifer would have trouble standing against his heavenly siblings, and sinners wouldn't last even a second. And what of the people from other worlds?

... But. What if God were just as ridiculous and clownish as Lucifer...? What if. What if.

Alastor is angry that he hadn't thought of it.]
