"This is bad. We're dealing with something stronger than an angel and that can overpower demons and vampires." Dean sighs, "What the hell do we do?"
Just as Sam's about to answer, his cell phone rings, "Hello?"
"H-Hi, officer Maldak? It's Cassandra, I-I think more of those… People are following me. I-I could really use your help!"
"Alright, just tell me where to meet you and we'll show up." Sam replies, concern in his voice, "The bakery? Sure thing."
He hangs up and looks up at Dean, "Let's go."
A short while later, the duo arrives at the darkened bakery.
"Cassandra?" Dean calls out. "Back here! I-I'm sorry, I was followed and Ms. Soldado said I can hide out here for a bit." Cassandra calls out from the back room. The Winchesters rush to the back only to find an empty room and the door behind them slams shut.
"What the-?!" Dean exclaims as a circle of holy fire surrounds a bound and gagged Castiel.
They hear heels clacking against the floor as a woman, the waitress from earlier steps into the light, dressed in what looks like typical wear for a biker, "Hello, boys."
"Who the hell are you?!" Sam yells out as the both of them level their guns. A simple flick of the wrist and their weapons would be pulled from their hands and they get pressed up against the wall by an invisible force. The woman snaps her fingers and Castiel's gag disappears from his mouth, "It's her… She's the angel I was telling you about earlier… Ariel, the Gatekeeper Archangel."
Her eyes glow and a shadow of a pair of massive wings forms on the walls behind her and she smiles, "Hello, brother."
"How are you still alive, general?" Castiel pants as he struggles against the chair's restraints.
"General?!" Dean grunts as he struggles against his invisible restraints.
Ariel sighs as she crosses her arms, leaning against a counter, "Because I never really died, Castiel. Faked my death those many, many centuries ago."
"So you're still alive, big whoop." Dean grunts, "How did you know who we are?"
"Oh, I hear a lot of things, living in the Windy City. And of course, Cassie here broadcasted your huge return all throughout the cosmos. DEAN WINCHESTER IS SAVED." She rolls her eyes,
"Please, you all totally bought the protective shopkeeper act. I was so hoping that you lamebrains would just storm into that club and literally get eaten alive. If you both are dead, there's no prophecy to fulfill. But you had to have Cas with you."
"Since you're still alive, Ariel, you could help end things with Michael and Lu-!" Castiel starts but the gag forms around his mouth again while she growls, "I refuse. I will NOT get back into that mess. Michael ended things with me when he stabbed me and threw me into the deepest trenches of the sea."
Another snap of her fingers and Castiel vanishes, "Look, I need a favor from you both. Do it and I'll let all of you live and walk out of my city alive."
"A favor? Seriously?" Sam grunts as the archangel releases them from the wall when Castiel disappears once more.
"Did I stutter, tree?" She glares at him as she crosses her arms.
Dean and Sam raise their weapons at her and she rolls her eyes once more, "Look, you both know that those types of weapons don't work on me, so don't waste the energy and bullets. If I really wanted to kill you, I would have done so already by strangling you both to death with your own sphincter muscles."
The Winchesters wince as they put their weapons away with Dean grumbling, "Fine. What do you need us to do?" Ariel frowns and massages her temple, "Those vamps kidnapped Cassandra. I can't go tearing through the city because I'm still technically dead. I need you both to look for her. Don't rescue her right away, just come back here and we'll figure out a game plan to go get her together. Got it?"
Before the boys can protest, she snaps her finger again and they're suddenly outside of the shop. Dean looks around, realizing this and curses, "Son of a bitch!"
