Gabriel didn't like this one bit. He was the only archangel left; yet, somehow Metatron had overpowered him. Gabriel hadn't seen that much power coursing through one being since his Father who'd disappeared so long ago. Metatron thought himself God, and he was almost right.
"Have you thought about my offer?" the sickening angel questioned as he stepped into the darkened room. "Really, brother, it's the best you'll get."
Gabriel wasn't ever one to show weakness (unless it's fake of course), so he only smiled in response, "Go to Hell Metatron."
"I might very well claim that too," the angel laughed. "But for now I just need the angels to take sides so I can win Heaven. I already own it of course, but no one will accept me as God until they realize none could beat me should they try. I need a villain to my story Gabriel."
"And you want me to be that villain? News flash everyone thinks I'm dead and I'd like to keep it that way."
"Not you," the arrogant angel replied with a laugh. "Never you. You with an army… I might actually lose. I want Castiel."
Gabriel pondered the situation. If he was like the rest of his brothers he would easily accept the offer to trick Castiel and go free, but Gabriel wasn't like the other angels. He actually cared about all of humanity in the way not even their creator had. But maybe if he did as Metatron asked and got Castiel to lead an army… if anyone (besides Gabriel of course) could beat the sickening angel it was Castiel and the Winchesters. Gabriel once thought them nothing but a nuisance, but Hell they'd stopped the Apocalypse. Gabriel hadn't even been able to do that! No, "Team Free Will" could beat Metatron if they had the right guidance.
Gabriel could be that guidance.
"One trick complementary of the trickster coming right up," the archangel promised with a grin. What Metatron didn't know was that Castiel had a rip in his coat, but Gabriel did know this because he's made sure it got put there. The angels little brother would be fooled for a bit, but eventually he'd see the big picture. Gabriel was useless beyond there; it was all up to a baby in a trench coat.
