Quotes
"Hail to the King, baby."

- Lucifer

"Mr. Ketch, meet the Archangel Gabriel."

- Asmodeus

"We're not in Heaven, we're on Earth. You may have noticed, around here? Good life ain't cheap."

- Anael to Lucifer

"After the Fall, Angels were a mess. Desperate for housing, any vessel would do, and they had no long game. I, on the other hand, took some care. I listened. A woman prayed for her dying husband, so we made a trade: his life for her vessel. She was grateful. I realized humans are so desperate for life. They'd do almost anything, pay almost anything. So... kaching! I was a so-so angel but turns out, I am an excellent businesswoman."

- Anael to Lucifer

"Dean: Alright, I say we take this dick-bag here back to the bunker, find out what he knows and put a bullet in him, burn his bones and flush his ashes. Castiel: I like that plan."

- Dean Winchester and Castiel

"I feel emotions, sensations, things they must feel (...) When I'm that place, I see how there'd be pain but there's also hope, love even. Angels can only imagine. Sometimes I envy humans, they can be anything."

- Anael
