Demon twins au where Danny left one last message to Damian before he faked his death. Years later, Danny shows up at Wayne Manor, and refuses to speak to anyone until he sees Damian.
His first words to his brother were from that last message
DPxDC Last Words
Damian looks at the boy sitting in Father's study. It's like looking in the mirror, except not anymore: a stretched out t-shirt and jeans with a hole on the knee instead of a black, fitted League uniform, a slouched posture instead of a proper stance, an unbecoming habit of biting his bottom lip instead of an emotionless mask.
But the eyes, blue like the winter sky, so unlike Damian's — their only difference once upon a time — are the same.
Damian still remembers that night. He remembers the metal hitting metal, the scream stuck in his throat, the pain in his side. He still has the scar. He remembers the run and the chase, and he remembers his brother, his twin, his other half, pressing his cheek to his.
He remembers the warm blood under his hands, the quiet breath over his ear, and the words that were only for him, whispered softly with a smile.
"After you die, which part of you will be the last to fail you?"
And then, he remembers the emptiness, the absence, the loss. Grandfather congratulated him on becoming the sole Heir, praised him for taking what was his and only his birthright. Grandfather was a fool.
Damian looks at the boy. Takes a small breath, opens his mouth, the old name rusty on his tongue, "Dany-"
"Your pupils," the boy suddenly cuts him off, staring right into Damian's eyes, the corner of his lip twitching, "They dilate."
Damian stops short, all the complicated thoughts and feelings inside him coming to a sudden halt and leaving him in complete silence.
He blinks.
Danyal's lip twitches again, and Damian finally realizes it's not a nervous gesture. The boy is simply trying to hide a grin.
Dilate. Die-late.
Something inside Damian's mind snaps, breaking his composure instantly, and he throws himself at his brother with a feral, animalistic growl, fully intending on clawing his eyes out. Just to show the insufferable moron how quickly his pupils are going to really die.
Danyal laughs, loud and cheeky. He blocks the strike because, of course, he does, but they fall down to the floor anyway, and then the whole rest of the family spills inside the study from where they were obviously eavesdropping, and the room becomes a mess in less than two seconds. Grayson is yelling, Drake is trying to hold Damian from another strike, Thomas is helping Danyal get up.
Father is still in the doorway, a helpless sort of expression on his face when he looks at Damian.
"Is he-"
"Father, this is Danyal al Ghul, my formerly believed to be deceased brother, alive and in his right mind," Damian sneers out, still glaring daggers at his twin, "But not for long."
Danyal snorts a laugh, a playful, challenging grin playing on his lips.
"Oh, you're on, Dami."
