God's Favorite Sons: Lucifer, Gabriel, Morningstar
Gabriel closed his eyes as he heard Lucifer's response, knowing that every word was true and that his brother would think nothing of snuffing Cas out like a candle. He'd known this fight was coming, wasn't even sure why he tried to avoid it. Seemed like it was inevitable -whichever reality they were in- that the two of them would face off.
His double nodded once, as if accepting Lucifer's terms. "Thought you might say that." In one motion, he swept Lucifer's hand from his shoulder and slammed his other hand into the archangel's chest, pushing with enough force to topple a building.
