First italics are flashbacks.
Driving up to a house, Dean glances at the angel sitting in the passenger seat. "Well that's a day I'll never get back." Soon enough, they get out of the car, Castiel leading the way as they enter the house.
Castiel freezes, holding a hand up to the human behind him as he tenses. "Dean, wait."
Donnie is already standing inside the cabin, back flaring with lightning in the shape of wings. Castiel can clearly see that Raphael now resides inside the human. The many light bulbs shatter around him, breaking from the large influx of the archangel's grace.
"Castiel." Raphael simply states, nodding to the seraph he probably doesn't feel like he deserves.
"Raphael." He bows his head, eyes not leaving the archangel's cold stare. Castiel walks forward, Dean following close behind him.
"And I thought you were supposed to be impressive." They're absolute. Dean scoffs at the thought that intrudes into his mind, looking around. "All you do is blackout the room."
"And the Eastern Seaboard." He shrugs as lightning flashes outside. "It is a testament to my unending mercy that I do not smite you here and now." Heaven's most terrifying weapon.
"Or maybe you're full of crap." Dean quips, giving Raphael a long once over. "Maybe you're afraid God will bring Cas back to life again and smite you and your candy-ass skirt. By the way, hi, I'm Dean."
Raphael rolls his eyes, stepping forward. "I know who you are, boy. And now, thanks to him, I know right where you are."
"You won't kill him." Castiel steps in, moving between the archangel and human. "You wouldn't dare."
"But I will take him to Michael."
"Well then." Another dark look is shot towards the archangel. "Sounds terrifying. It does. But, uh, hate to tell you, I'm not going anywhere with you." He opens the fridge to grab a beer.
"Surely you remember Zachariah giving you stomach cancer?"
"Yeah, that was, that was hilarious." Castiel shoots Dean a dark look, not finding the sarcasm funny.
"Well, he doesn't have anything close to my imagination."
"Yeah? I bet you didn't imagine one thing."
"What?"
"We knew you were coming, you stupid son of a bitch." Dean flicks open his lighter and lights it, dropping it to the ground. As soon as it does, a circle of holy oil ignites around Raphael.
"Don't look at me, it was his idea." Dean points to Castiel, sliding away from him.
"Where is He?"
"God?" Raphael asks. "Didn't you hear? He's dead, Castiel. Dead."
