Curate, connect, and discover
A TaliaxDanny idea that came to me.
Damian, Bruce, and the rest of the bats discover the Talia al Ghul they had been fighting against, the one that cloned her own son, had the clone kill him, plant a control device in him when he broke his spine, etc etc was actually not the real Talia al Ghul.
Turned out Ra's had cloned her and killed the original when she discovered his little plans to take over Damain's body and she confronted him about it. Ra's had to make a clone when after tossing a dead Talia into the pits but never returned (he meant to kill her as a warning, as a "you may be my blood but will not hesitate to end you Talia.") It explains so much to Damian when remembers how out of nowhere his mother changed, her training him changed from harsh to deadly, the soft motherly love she would give him when behind closed doors suddenly stopped, the tales she would spin for him about his father no longer whispered to him for bed.
How this was find out?
Well it's hard to ignore the facts that when your foolish grandfather in his quest for immortality summons an eldritch being known as the Ghost King into the Mortal Realm and uses Damian as a sacrifice while his (not) mother watches emotionless.
When the being appeared, plunging the room from green glowing flames and the glow of the Lazarus Pits into darkness before a cosmos exploded to life, its glowing green eyes snapped open in the stars and stared at them all. Making every single one of them feel small, so very small.
It took a single glance around the room before stopping on the al Ghul's. It's eyes widen before a steel and firm look entered them. Just as quick as the cosmos sprang to life, it suddenly swirled away into a ball, putting them all back into the Lazarus room,and reformed in front of them to a more humanish height and body.
When the body, around the height and build of Batman, was done forming it took a step forward and suddenly as one blinked a man stood in front of them. Or rather floated. Snow white hair that flickered and wisped towards a crown made of fire and ice, glowing green eyes that held none of the madness but all of the power the Lazarus Pits could give. His clothing were tailored made that were tastefully a mixture of black and white with some silvers and greens, clothes fit for a King one would say. The cosmos that once engulfed the room had shifted into a cloak that hanged around his body, on one side more than the other (think like how CW wears his only the hood is down).
This, this was no doubt the Ghost King, he stood tall and regal and made everyone in the room feel the need to look down, to bow ones head for even just a moment. Even Ra's had trouble disobeying the urge to do so.
"Well..." the being said, his voice deep but not as gravely as Batman's was "What an interesting way to meet my In-Laws and Step-Son..."
He has said that as he looked towards the al Ghul's. Damian flinched back with a frown of confusion and disbelief while Ra's looked panicked for a second when the words registered into his mind, meanwhile Talia... looked emotionless and barely even twitched.
"What the fu-?" Someone began only to stop when the King lifted his hand and with a snap of his fingers a green portal appeared, it looked almost like the Lazarus Pits but it felt... cleaner? Less angry?
"My Bellatrix, my warrior star. I believe I've been summoned to your home dimension. And judging by the looks of it your father created a barely functioning Mirror of you and planned on using your son as a sacrifice to me." He spoke out towards the portal before holding his hand out.
A hand appeared from the portal, a slender hand and with green and black painted nails manicure to perfection before someone walked through it as they took hold of the Ghost King's offering hand.
Standing in front of them was another Talia, only this one looked a tad older than the one in the room. She wore clothing that matched the King to a T but even then, as always, Talia looked deadly in it. Beautiful but very deadly. From the heels she wore to the crown upon her head, a crown made of not ice and fire but of stars and black jewels. Her eyes were sharp as she stared at everyone in the room, frown on her painted lips, but her eyes lit with a small soft joy when she saw Damian only for them to turn poisonous when they landed on Ra's and the other Talia nearby.
"I should had know you would had created a Mirror of me instead of admitting to my son you killed me Father." Queen Talia spat out. "The least you could had done was not make my Mirror so cheaply, it doesn't even have a proper soul attached to it."
