"I thought I told you both not to look for me again. I now have more important matters at hand." Said Castiel glaring at Sam and Dean.
"Well fuck me Cas, it's not like I wanted to call you. This Padre guy here made me." Dean points exasperated to the priest sitting by the table.
"Jimmy, are you there?" says the priest.
"Ah, Mark. What an honor it is to finally meet you. Jimmy has the fondest memories from you and I thank you for offering your life to my father's cause, which is now my cause."
Mark's puzzled expression turns to one of worry. To Dean he asks "For how long has this thing been taking over Jimmy's body?"
"A couple years now." Answers Dean grimly, noticing Castiel's mood change the moment the angel, now God, looks at Mark again. This time with a look of hatred.
"This thing? You dare to insult your lord?"
"My lord? My Lord? I've spent most of my life praying and serving to a God who let you take over my brother's body and took him away from his family. A God who also, from what I've heard from these guys," points to Sam and Dean, "deserted humanity and refused to step up to the plate and save the world. I chose him over my family and look where it's gotten me."
"It has gotten you prestige, and respect from your fellow priests as one of the best exorcists from the Vatican. You have a bigger family now, and you get the opportunity to serve me."
"Yeah? Well guess what? I am tired of this crap I refuse to live a life where I'm not happy any longer and I refuse to serve you. Give me my brother back."
"I'm afraid I cannot do that." says Castiel glaring at Dean, one of the private glares they saved just for each other when they wanted one to know the other was in trouble.
"I said, I want my brother back!" yells Mark lunging at Castiel who vanishes in midair making him trip and land on the floor.
"Hey man, are you alright?" Asks Sam while helping Mark to get up.
"Sorry about that, Castiel and his feathery ass hasn't been the same ever since he went to that all you can eat buffet of souls." Dean says guiding Mark to the nearest chair.
"Is there any way that we can get that thing out of my brother?" Asks Mark.
"That thing as you call it used to be our friend and he wasn't always like that." Says Dean defensively.
"We want him back as much as you want Jimmy back. But I'm not sure you'll ever get him back. He struck a pact with Castiel letting him take over his body forever, I'm sorry." Sam looks apologetically to Mark and hands him a drink.
"Jimmy was always a man of faith. I guess he had his reasons for doing that…Can we at least stop that asshole from being God at all, though? He really pissed me off." Mark gulps his drink and nods to Dean to fill up the glass again.
"That's what we're trying to do. We want our old Cas back but we need to do a lot of digging around before we can do that. You in?"
Dean looks Mark straight on, waiting for his answer. Mark gulps his second drink and rips off his white collar from his neck.
"Count me in."
