Anna compares angelhood to being a marble statue. "Cold. No choice. Only obedience." I call b.s., Anna. You had a choice. Had you not -- had you not been able to exercise free will -- you wouldn't have been able to cut out (blergh) your grace kidney. You didn't obey; you rebelled. Tsk. She's not listening to me; she just keeps talking to Dean (not that I blame her, there). "Dean, do you know how many angels have actually seen God -- seen his face? Four angels. Four. I'm not one of them." She says the rest of them have to take it on faith that there is a God, and they're killed if they don't have that faith." And? Here comes our morsel. "I was stationed on earth two-thousand years. Just watching. Silent, invisible, out on the road, sick for home -- waiting on orders from an unknowable father I can't begin to understand, so don't tell me that..." her voice trails off as Dean laughs. "What is so funny?"

Dean rubs his face and tries to settle down. "Nothing, sorry, it's just...I can relate." They consider one another for a moment, and just as Dean raises his eyebrows in a how you doin' sort of way, they're interrupted by Sam. I bet as an angel, Anna didn't have a younger sibling totally cramping her style. Oh wait, I forgot about Castiel.

Inside, Sam tells the gang about a miracle in Union, Kentucky. In '85, there was an empty field outside town, and within the space of six months, a full grown oak sprang up overnight, and it appeared to be a century old. Anna thinks this has to potential to be where her grace kidney landed. Dean says, "So grace Ground Zero? It's not destruction; it's..."

Anna finishes for him, "Pure creation."

Or piss. Which comes from kidneys, and can be cut out with butter knives.

We get a shot of Metallicar driving down a beautifully wet road. Inside her, Dean drives; Sam rides shotgun; and Ruby and Anna share the backseat. Dean chuckles about a demon and an angel sharing that backseat, comparing it to the set up to a bad joke, or a Penthouse forum letter. Sam says, "Dude. Reality. Porn." Dean scoffs at any of this being reality. If this is porn, I don't want to see the rest of it, thanks. Baby's motor hums as if she too is trying to get through this as quickly as possible. I suspect she doesn't care for either of her new passengers, who probably haven't taken the time to learn the rules.
